Re: [c-nsp] problem with VPC port-channel between Cisco 3550 and pair of Nexus 5020
Hi, You may find the Nexus 5020 has blocked the port because it has received a spanning-tree bpdu from the 3560. You could apply the following command on the 3550 uplink: spanning-tree bpdufilter enable Whilst this is safe enough on a single link, I would be very careful about applying it in a redundant/port-channeled scenario.

[c-nsp] IP Source Guard and Smartlog on 3750s
Hi, I'm looking at implementing IPSG on our 3750s. This is a test which stops a host using a port unless its mac-address/host-address match the ip dhcp snooping table. This works fine. IOS is 15.0(1)SE2. The specific hardware is Catalyst 3750G-24PS. My problem is that I want to be alerted when there is a violation. You can't configure traps for IPSG, and there is no syslog entry (from which I could use EEM to generate a trap). The only method offered by the IOS is to use 'smartlog' which sends specially-formatted netflow-v9 messages to a specified collector. It is not possible to manually configure 'flexible netflow' on the 3750 – but I don't know if that would help anyway – except that I would be able to see the records on the switch without sending them to a collector. I've tried a few different collectors – the only one I've found that understands the records is 'Scrutinizer'. It sees the record as an IPSG violation but provides nothing else except the vlan number. (What I would like is the interface and the offending ip/mac). Looking at the raw netflow data via nfcapd/nfdump confirm that the vlan is the only useful field that is sent. I can't find any Cisco documentation on how to interpret the netflow records generated by SmartLog – what the format is; what collectors understand them etc. But if the record only contains the vlan then they are not much use anyway.

Re: [c-nsp] Nexus 2k - host ports
Hi Simon, We came across a similar problem where we had no choice but retain some Cat3750s in between the servers and our N2Ks. On the connecting ports on the 3750: spanning-tree bpdufilter enable Not a great workaround, but is only short-term. I'm not familiar with ILO but assume it is some sort of server management port. Where I am they are Dell servers and DRAC ports (I think). Whatever, they also are 100Mbps only. Driven by the absence of 100Mbps ports on our N2Ks, it motivated us to set up a separate "out-of-band" management network based on spare Cat2960s and Cat3750s.

Re: [c-nsp] Nexus equipment in corporate networks
Hi, We have two datacentres with L2 spanning them - for this we use the Nexus OTV feature (provides L2 over L3). You can't run SVIs on the same vDC as you use for the OTV edge device - hence a separate vDC is mandatory. In addition we use two vDCs with VRFs to provide security tiering (in conjunction with ASAs and load balancers). Yes, we could use VRFs exclusively but having two separate vDCs makes it cleaner. We also have a separate management vDC - very handy but a luxury, not a necessity.

Re: [c-nsp] Nexus OTV Question
Thanks Lincoln, The problem isn't associated with a single mac-address moving between ports - at least I don't think so. Everything seems to be behaving as expected - except for the "sh otv route" table. For clarity, I configured only a couple of vlans over OTV. The otv route table quickly stabilises and can be reconciled against the originating device. Then, a new mac-address appears or disappears. What then happens is that the uptime for all pre-existing mac-addresses resets to zero. This is not what I would expect - I would have expected the uptimes for the pre-existing mac-addresses to continue to increment. Then, as I add vlans (100 or so), the number of mac-addresses increases dramatically, and of course the probability of a change to the table increases. Consequently the frequency at which all of the uptimes reset to zero increases. This then gives the impression that the system is quite unstable - which I don't believe it is.

[c-nsp] Nexus OTV Question
Hello all, We have a pair of Nexus 7Ks at each of our two datacentres, separated by about 10K. There is a 40G L3 connection between the cores at each site and we run OTV over this core to provide L2 connectivity betweens the DCs. As well as setting up new vlans on the Nexus kit (5Ks and 2Ks) we are also using the OTV connection to transport vlans from our legacy datacentre which is based on Cat6509s and 3750s. I have a concern about the table that is displayed when you enter the command "sh otv route". This table shows entries for "site" (ie local) and "overlay" (ie other DC) mac addresses.The issue is with the "Uptime" data. For the overlay addresses this will randomly reset to zero and all addresses will reset to zero at the one time. The frequency of this reset seems to be a function of the number of vlans ie the more vlans I add to the overlay, the more often the value resets. With 100 or more vlans the value may build up to a minute or two but will often only get to a few seconds before resetting. This doesn't appear to impact the functionality of OTV. But does it indicate I have a problem ? What is it that causes the reset and why are all the (overlay) mac addresses reset at the same time ?The symptoms occur whether or not "otv suppress-arp-nd" is enabled or not.

Re: [c-nsp] How to run a scheduled script to grab interface stats
If you can't use SNMP or don't want to use expect, then another method which is available on the Catalyst 3750 (can't vouch for other platforms) is to push information out via tftp. sh int | redirect tftp:/// This can be put in a cron job (called kron by cisco) so that the info can be sent on a regular basis. eg to push out the result of 'sh int' every 10 minutes: kron policy-list DO-SOMETHING cli sh int | redirect tftp:/// kron occurrence DO-SOMETHING-REGULARLY in 10 recurring policy-list DO-SOMETHING Then you just need a script on the tftp-server to parse the received file and put it in a form that suits.
