[c-nsp] NCS-5501/NCS-5502 as border/core routers
All, I'm currently trying to plan some upgrades for one of my networks where we currently use Cat6500/Sup2T as both 'core' and 'border' routers, but are very rapidly outgrowing them. I've recently split off the L2 transport aspects from the 6500's onto 100G capable switches (I ended up using Extreme X690/X870 here) which has freed up some capacity, but now looking at what to do about the L3 routing aspects, working with full Internet routing tables. I'd always planned to move up to the ASR9k for this, but the price of 100G ports for them is eyewateringly expensive when compared to switching boxes. I then stumbled across the NCS-5501-SE and NCS-5502-SE boxes. These, on paper, look ideal - the 5501's as border routers with 100G uplinks to the core, and the 5502's as core routers in our main datacentres. In particular, the 5502 appears to give me 48 x 100G ports for way less than the cost of ASR9k with just 4 x 100G ports. I fully recognise the difference between L3 switches (which I see the NCS boxes as) and true routers - I've been using the Cat6500 in this role for 7+ years! Are there people on this list who are actively using these boxes like this? Any gotchas, recommendations, scare stories? Does anyone understand the licensing on them? I've struggled to find any Cisco published information about what is/isn't included in each of the license options...

Sorry. Quite :) Recommending software versions is one thing TAC cannot do - either by policy, or by demonstrated skillset. We did a big upgrade programme on some Cisco devices over the Christmas period to fix a number of bugs that had been raised to TAC. We upgraded to the version that TAC recommended to fix these bugs. We hit other bugs after the upgrade. We spoke to our Cisco SE about this, and he instantly responded to say that TAC should never have recommended that particular version, and that it's documented on CCO which version we should have used. We were also told that if we wanted Cisco to do a 'bug scrub', to see if we would be affected by any known bugs, then they offer this as a seperately chargeable service. Yes, really, they want us to pay them more money to find out how buggy their code releases are...

I can only assume the Nexus is looking this deep in the packet to get some entropy for load-balancing hashing. Trying to persuade Cisco TAC that this is a real problem with the Nexus, and not a problem with the packet has been a real challenge.

[c-nsp] Wierd MPLS/VPLS issue
All, Having banged my head against a brick wall all day today trying to work out what's going on, and not having got anywhere, I thought I'd ask this list for some suggestions... I've got a Cisco MPLS core network, with Extreme boxes running as VPLS endpoints. Over the last couple of days I've tried turning up additional capacity between two core nodes, and each time I try, I end up with packet loss over VPLS links (either full or partial loss), but only on a subset of VPLS instances. Simplified network diagram: +--+ | vpls-m | | | +---+--+---+ | | | | 2 x 10G LAG | | +---+--+---+ +--+ | core-m | 10G | sw-m | | +---+ | | | +-++ +--+-+-+---+ | | | | | | | | 3x10G | 100G VLAN Trunk | | | ECMP| | | | | +--+-+-+---+ +--+ | core-l | 10G | sw-l | | +---+ | | | +--+ +---+--+---+ | | | | 2 x 10G LAG | | +---+--+---+ | vpls-l | | | +--+ vpls-m and vpls-l are Extreme X670-G2's (running EXOS 16.1.3.6) core-m and core-l are Cisco 6500's with Sup2T (running IOS 15.2(1)SY2) sw-m and sw-l are Cisco Nexus 92160YC's (running NXOS 7.0(3)I4(3)) The three existing 10G links directly between core-m and core-l are live now, over carrier 10G EoMPLS links. Typical config for the 10G link is: interface TenGigabitEthernet1/1 description to core-l:Te1/2 mtu 9000 ip address xx.yy.zz.234 255.255.255.252 ip pim sparse-mode logging event link-status load-interval 30 ipv6 enable mpls traffic-eng tunnels mpls ip ipv6 ospf 1 area 0.0.0.0 hold-queue 4096 in end The new 10G link I'm trying to add is going via sw-m and sw-l, over a 100G wavelength from a carrier. All the ports on sw-m and sw-l have an MTU of 9216 configured, with the port facing core-* as a "switchport access" port, and the 100G link configured as a "switchport trunk". Config on the core-* ports towards the sw-*'s is the same as above (except I'm using /31 for the IPv4 addresses). IPv4 and IPv6 reachability is fine. OSPF, OSPFv3 and PIM come up over the link. As soon as I configure "mpls ip", I start getting the packet loss over some VPLS links. Remove "mpls ip", and the packet loss goes away. To me, everything *looks* right, it's just that some VPLS traffic traversing the new link gets lost. Anyone got any suggestions on what I should look for whilst troubleshooting this? Unfortunately, due to the impact to traffic, I have to make any changes within a maintenance window, but I've run out of ideas of things to try or look for.

My thoughts exactly. Just to confuse matters a bit, we don't buy these cards direct from Cisco, so don't have direct TAC support for them. We use a 3rd party support partner. The card with the warning was actually supplied by them as a replacement for a failing card that's currently in live service. Whilst I'd probably accept a written assurance from Cisco that it's fine, I'd not accept the same from the 3rd party partner, as when we move onto another support partner in the future, they'd be under no obligation to honour the agreement.

[c-nsp] Can you upgrade WS-X6908-10G-2T to -2TXL?
All, We've recently received a WS-X6908-10G-2T which has been 'upgraded' to a -2TXL by replacing the DFC-4 with a DFC4-EXL. When we install the card in our 6500, we get the following warning: May 3 05:49:10.566 UTC: %SMC-DFC4-2-BAD_ID_HW: Failed Identification Test in 4/0/1 [5/0] The module in 4/0/1 in this router may not be a genuine Cisco product. Cisco warranties and support programs only apply to genuine Cisco products. If Cisco determines that your insertion of non-Cisco memory, WIC cards, AIM cards, Network Modules, SPA cards, GBICs or other modules into a Cisco product is the cause of a support issue, Cisco may deny support under your warranty or under a Cisco support program such as SmartNet. The module also shows as Status "Warning" in "show modules". The Vendor is saying that this is just cosmetic and because the DFC4-EXL isn't what was shipped with the original card, but I'm not happy, so pushing for them to supply a card which doesn't have this warning. Has anyone done this before? Anyone seen this before?

Sounds like you come from the Cisco camp of performance testing :) Yes, under ideal conditions you can probably get close to linerate on them, but stick general Internet traffic through them, and you won't.

The WS-X6704 has woefully underpowered ASICs on it. It has the dual 20G bus connections, with two 10G ports on each, so on paper it's not oversubscribed.

On Sat Jan 17, 2015 at 10:53:01AM +0200, Chris Knipe wrote: I'm still confused :-( Sorry. The only other line card in the chassis would be one WS-X6748-GE-TX which is a 48 Port 10/100/1000 card. With 6704 and 6748-GE-TX you'll be in CEF720 switching mode, not classic. This will give you the full 30Mpps switching with CFC's. Yes, the SUP720 comes with MSFC3/PFC3 standard (we will be upgrading memory on the SUP as well as the MFC to 1G, the max supported), and it states it can deliver up to 40Gbps per slot. But from what you've mentioned, we will thus now be limited to 15Mpps which is clearly not going to be enough. If you're only doing layer 2 switching and no routing, then you shouldn't need to upgrade the RAM - this is used more for route storage (RIB). The SUP720-3B is perhaps also an option, but if I have to start looking at the 720-3BXL then it's becoming very expensive, yet again. Consider looking at refurb / 2nd-user - either official Cisco refurb or 3rd party. You'll probably be pleasantly surprised by the pricing. Do I then also understand correctly that in the case of a SUP720-3B I need to purchase a WS-X6708-10G-3C and in the case of a SUP720-3BXL we are talking about a WS-X6708-10G-3CXL (there are no 4-port line card available with a DFC daughter card), or are these special versions with the daughter cards only required to lower the impact of the contention on the 8-port cards? The 6708 is an odd card - it has the DFC 'soldered in', so it's not field replaceable/upgradeable. The difference between 3B and 3BXL is purely the number of layer 3 routes it can hold in the FIB. If you're only doing L2, then this won't give you any benefits. Would the same also hold true then on a SUP720-3B or SUP720-3BXL in the case of a WS-X6704-10GE, or would the bigger (better) SUP have no problem with smashing the 15/30Mpps to pieces and deliver true 10Gbps per port? I'm not after 100% guaranteed 10Gbps per port on the line card, but I most certainly don't want to spend all this money and only get like ~3Gbps per port either. You won't get true line rate on all 4 ports on a 6704. They're well known as having performance issues due to underpowered ASICs. We've been seeing about 25-30Gbps of aggregate traffic (general internet traffic, adding in+out on all ports) before they run out of steam. What other options (except Nexus) would there be that can deliver ~8 x 10GE (fiber) and 48 x 1GE at an affordable rate? Depends on your total traffic requirements. SUP720 + 6704 + 6748-GE-TX (+ 6724-SFP if I need fibre) is still my work-horse of choice for a Cisco switch offering both 10G and 1G ports. On the used market, these blades are available very cheaply. Nexus is WAY over my budget (and the reason why we're looking at the 6500 instead), and it would seem (to me at least) I am stuck between a rock and a hard place in terms of acquiring a low port density 10G switch at an affordable price. Although I don't use it myself (as I use Extreme X460 switches for this purpose), you may find something in the Nexus 3000 range which fits your requirements. Sorry for all the questions, in my 15 odd years of networking, this is the first time that I will be entering the 10GE arena, so I really want to just make sure that I get the correct kit from the start. These toys aren't cheap :-( Wait until you want 40G or 100G - then you'll realise that 10G stuff is cheap :) Simon -- Simon Lockhart | * Server Co-location * ADSL * Domain Registration * Director| * Domain Web Hosting * Connectivity * Consultancy * Bogons Ltd | * http://www.bogons.net/ * Email: i...@bogons.net * ___ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/

SUP720 + 6704 + 6748-GE-TX (+ 6724-SFP if I need fibre) is still my work-horse of choice for a Cisco switch offering both 10G and 1G ports. On the used market, these blades are available very cheaply. This is what I really like (and hoped) to hear. Considering we're currently peaking at 1.2Gbps / 1.5Gbps, a ~10X increase in capacity/throughput seems like a winner then. Granted (as I understand it), from a layer III point of view this configuration would be significantly under spec'ed to provide what it is supposed to, but on a layer II level it seems (to me at least) that it would be able to deliver a -significant- upgrade to what we currently can deliver on our infrastructure... I'm doing L3 on my 6500's, so I do use the 3BXL to be able to hold a full Internet routing table. There's little difference between L2 and L3 performance on the 6500. We're now upgrading to the Sup2T and 69xx cards to give us higher 10G port density. The 25-30Gbps you are seeing - is this across one line card, or across the entire chassis? Just trying to get an idea of what two or three 4-Port 10GE cards would do. That's per 6704 card. In aggregate, we were probably doing close to 100Gbps of traffic through a 6509 chassis, but only because traffic was flowing over it several times.

Re: [c-nsp] ASR vs 6807
In simple terms (and I apologise if this is fixed in Sup2T, as most of my experience has been on the Sup720), with the 6500/6800 platform, you can only do port-to-port or subint-to-subint VPWS, but not port-to-subint (which you can on the more capable boxes, or with the ES cards on the 6500/6800).

[c-nsp] Exactly how bad is the 6704-10GE?
All, (This is vaguely related to my question earlier in the week about ASR capacity) We use quite a few 6704-10GE blades on our network, and I'm seeing some random congestion type issues. In some cases, I've made the problem go away by shuffling ports between blades to spread the load, but I'm left wondering exactly where the problems lie. From talking to people on IRC, etc, I'm told that the 6704 runs out of steam around 24-26Gbps of throughput when handling imix traffic. I'm also told that this is largely driven by pps, rather than bps. If we take, for example, a 6504 on our network. It has a Sup2T in slot 1, 6704-10GE(CFC) in slot 2, 6724-SFP(CFC) in slot 3, and 6904-40G(DFC4) in slot 4. I've got a 4*10G portchannel towards our core consisting of Te2/1, Te4/5, Te4/6 Te4/8 Te2/3 and Te4/9 form a 2*10G portchannel towards an IXP Te2/2 is a 10G link towards a transit provider. The traffic profile on the 4*10G portchannel seems to max out at about 24Gbps. I don't see any obvious packet drops or latency increase, just that the traffic doesn't go any higher than that. I suspect I'm hitting a limit on the 6704 which is causing this, but I can't figure out what that limit is. If I take a snapshot of the 3 active ports on the 6704 at peak time, I see: Te2/1: In = 2.7Gbps/580kpps, Out = 5.7Gbps/613kpps Te2/2: In = 7.0Gbps/865kpps, Out = 1.8Gbps/520kpps Te2/3: In = 7.3Gbps/789kpps, Out = 2.5Gbps/666kpps Summing that all up, I've got ~27Gbps of traffic flowing through the card, and just over 4Mpps. I also see this: rtr#show fabric drop Polling interval for drop counters and timestamp is 1 in seconds Packets dropped by fabric for different queues: Counters last cleared time: 22:54 08 Oct 14 slotchannelLow-Q-drops High-Q-drops 1 0 0 0 1 1 0 0 2 0 35759 @00:57 09Oct14 0 2 1 76766 @00:57 09Oct14 0 3 0 0 0 4 0169 @00:56 09Oct14 0 4 1 0 0 So I seem to be seeing fabric drops on the 6704 slot, on both channels (but more on channel 1, which has ports Te2/1 and Te2/2 on it). If I look at fabric utilisation, it doesn't say it's maxing out: rtr#show fabric utilization detail Fabric utilization: IngressEgress Module Chanl Speed rate peak rate peak 1 020G0%0% 0%0% 1 120G0%3% @19:53 08Oct140%3% @19:53 08Oct14 2 020G 27% 50% @22:14 08Oct145% 13% @22:13 08Oct14 2 120G 33% 47% @00:33 09Oct14 23% 33% @23:09 08Oct14 3 020G0%0% 0%0% 4 040G 11% 17% @22:30 08Oct14 26% 40% @00:02 09Oct14 4 140G0%0% 0%0% So my questions... 1) For other people using the 6704-10GE blade, what sort of maximum throughput are you seeing? Have you managed to pinpoint what the limiting factor is? 2) What do the fabric drops really mean. My google-fu isn't helping a lot, and the command doesn't seem to be documented. Is there anything I can do to reduce the fabric drops? Why am I also seeing some on the 6904-40G slot, which should be a much more capable card.

Re: [c-nsp] Understanding ASR1k / ESP40 capacity
Pete, Thanks for this - I'll watch that preso and see if it adds anything useful. You seem to be supporting my viewpoint, and I've also had an off-list reply supporting TAC's viewpoint - so I'm not sure I'm any further forwards. I'm currently working on a plan to replace the ESP40 with an ESP100 - but as the ESP100 isn't supported in the ASR1004, I'll also have to do a chassis swap to an ASR1006. My only remaining concern with this plan is whether the SIP40 can really do 40Gbps. If I stick 4 * 10G SPA's into a SIP40, can I run those 10G ports at line-rate (assuming sufficient ESP capacity)?

Obviously I don't want to manually create tens of thousands of subinterfaces on a router, and I'm sure there's a better way of doing this.

[c-nsp] ASR1004 and NAT limitation?

[c-nsp] Making SUP720 cope better under BGP load
All, I'm currently using SUP720-3BXL's in my BGP border devices. Obviously the SUP720 is not a particularly fast CPU, so it is pretty slow at bringing up a lot of BGP sessions. On one particular box, I've got 250 BGP neighbours - 1 full table transit, 2 IGP to route-reflectors, and the rest are peering sessions at an IXP. Recently, the IXP did maintenance causing the interface to drop, and it bought the box to its knees. The BGP Router process takes all the available CPU while it tries to re-establish the BGP sessions. While this is happening, the SUP720 seems to give up processing other stuff in a timely manner - and I see MPLS LDP drop, OSPF neighbours drop, and then BGP sessions drop due to hold timer expires. With all these drops, it causes even more CPU load, and the cycle continues. I've been talking to other SUP720 using ISPs, and it seems that some see this same effect, and others don't. Currently running 12.2(33)SXJ3 Are there any tweaks that I can apply to the IOS config to make the SUP720 cope better in this sort of situation? I'd be happy for the BGP sessions to take a lot longer to re-establish, if it didn't kill everything else in the process... And, as a follow-on question, given that the SUP720 is so under-powered for BGP, what other options do I have which would cope better? SUP-2T? Or, if I need to move away from the 6500, what's good for BGP routing with about 20-40G of throughput (i.e. 4-8 * 10GE ports)? How does the ASR9k or ASR1k range fair for BGP performance?

[c-nsp] Understanding ASR1k variants
Cisco-NSP'ers, Due to a requirement to deploy CGN, I'm looking at the Cisco ASR1k range for the first time, and I'm a little confused about the different variants of RP, ESP, SIP, etc - and I'm hoping someone can clarify things a bit. I'm looking for a box which can route 10GE to 10GE at linerate. What's the difference between the RP1 and RP2? The only obvious difference from reading the datasheets is the amount of memory? With the ESP, because I want to route 10GE to 10GE, is it right that I need the ESP20, as I'm looking at 2 * 10GBps of traffic (ingres + egress)? Likewise with the SIP, the SIP10 won't be fast enough for full 10GE to 10GE, so I need the SIP40? Bringing this all together, if I'm looking for a box that can do 10GE to 10GE, then the smallest ASR1k that will do this is the ASR1002-X? As well as the chassis, I'd need to buy the 20Gbps license, the IP Base license for the RP, and 2 * 10GE SPAs?

[c-nsp] QinQ on 3550 not working?
All, I've got a requirement for one of our customers to run two seperate networks over the same ethernet based WAN. The WAN is provided by the carrier as single VLAN per site, dot1q tagged at each end (both the customer site and our central PoP). The customer sites are all live currently with a single network to each site, and have either a 3560 or a 3550 running ipservices software images as the layer 3 device for the site. It would appear that QinQ is a good solution to this problem, and I've got it working in the lab where the edge router is a 3560, but if I put the same config onto a 3550, then it doesn't work - and I'm stumped as to why.

Does anyone try to use CVR-X2-SFP (Cisco TwinGig Converter Module) with cat6500 WS-X6708-10GE module. I try to insert it but have bad EEPROM. I would not expect them to work anywhere but on the 3750E, at least for now. Given that (as far as I can work out) they work by having both X2 and SFP connectors at the back of the slot in the switch, then I'm not surprised that they don't work in the 6708 module. We use them successfully in 3750E's.

Re: [c-nsp] Cisco noob -- design guidance request
On Sat Sep 01, 2007 at 10:12:07PM -0600, David L. West wrote: I'm setting up a new LAN in an office building with multiple tenants who will be sharing internet access, DNS/DHCP but have individual VLANS to keep them seperate from the other tenants. I think that the key here is having each VLAN have a helper address that serves as a DHCP Relay Agent , which in turn is how the DHCP server knows which range to hand the client. Yup - this is a standard design for multi-subnet DHCP. After a lot of googling, I came up with a configuration that I think will allow all the VLANs to share a DNS/DHCP server, and am detailing it here in the hopes of getting some indication of whether I'm on the right track. You're almost there... The server has a NIC configured with multiple IPs, like so: 172.16.0.1 / 255.255.255.254 ; Subnet 0 -- Reserved for switches routers 172.16.2.0 / 255.255.255.254 ; Subnet 1 -- Reserved for network servers 172.16.4.0 / 255.255.255.254 ; Subnet 2 -- First tenant subnet (VLAN 102) 172.16.6.0 / 255.255.255.254 ; Subnet 3 -- First tenant subnet (VLAN 103) ... 172.16.0.255 / 255.255.255.254 Subnet 127 (VLAN 227) You don't need to do this. Assuming you're only doing this for DHCP, then the server does not need to be in every subnet. By configuring ip helper address the switch will do DHCP relay, and turns the DHCP request into a unicast request to the server, and adds something to the request to tell the DHCP server which subnet it should allocate the address from. This NIC is connected to a switch port configured like so: interface GigabitEthernet0/12 switchport trunk allowed vlan 30,102-227 switchport mode trunk spanning-tree portfast No need - just configure the server as a access port on the switch in the vlan for 172.16.2.0/23 and give it an IP in that subnet (e.g. 172.16.2.1) The Vlans 102-227 are derived by adding 100 to the subnets above, so VLAN102 is: interface Vlan102 ip address 172.16.5.254 255.255.254.0 ip helper-address 172.16.4.1 no ip route-cache Configure ip helper-address 172.16.2.1 rather than what you have. DHCP is running on the server with a dhcpd.conf like so: Sorry, I can't remember the exact syntax for the dhcpd.conf for this, but you just need to add a subnet {} section for each of the subnets, and it'll work out what you mean...

No - you just need one Layer 3 device, with an interface in each subnet.
