Interested to see longest uptime on a switchstack. Cannot imagine it being more 
than 4 years.
Stack disease always comes at you before long.

Re: [c-nsp] Cisco 8000

[Ed Ronayne]

Hi

Came across that 920 model the other day. 
Will be useful. But the single AC PSU would make it difficult for us to use. 

Dual DC is in the line up but not AC unfortunately 

Regards


Ed

Re: [c-nsp] [Retrieved] Fiber issue, banging my head.

[Ed Ronayne]

As Rick as saying.

Have you tried putting an attenuator on the fibre.

Maybe you're over cooking the RX side on one of the SFP's

Ed

Hi,

We're still having issues with this Fiber Gig-e Connection between our
Catalyst 6509 and our Cisco 12000GSR.

We have tried 6 different SFPs (all multi-mode)
We have tried 2 different cables (multimode)
We have tried two different cards on the Catalyst 6509 (port g5/1  g6/1 on
the Supervisor 720)
We have tried two different gig-e cards on __two different GSR 12000s__
We have tried auto-neg, non auto-neg
We have disabled flow control on the switch side

The problem we're seeing is CRC errors and Input errors on the router side,
the sh interface output from the switch side is completely clean.

We have 3 other setups which are virtually identical (same cards, sfps,
cables, gbics) and they work fine.

Any ideas would be greatly appreciated, starting to think I'm cursed.

Thanks,
-Drew

As stated before, check SFP type, and make sure your fiber and SFP types
match.  You can see a link come up on a MM SFP with SM fiber but link
will not work properly.

Also verify that you are not overpowering your SFPs (i.e. your optical
power levels are in spec with the cards RX specs)

Hard code speed

Unless you have a transport system between the 2 devcies, SFPs should
match (i.e. SM or MM on both sides)

Hi there.

We are trying to connect a Catalyst 6509 connected via fiber to two GSR
12000 routers.

When we connect the switch to the router(s) via G5/1 and G5/2 (on the
Supervisor 720) we get input errors on the Router (the GSR side), the
line goes up/up but we see:

Received 0 broadcasts, 0 runts, 0 giants, 0 throttles
 1668 input errors, 1668 CRC, 0 frame, 0 overrun, 0 ignored

The throughput between the two pairs is also terribly slow.

We have tried different cards in the GSRs, we have tried different fiber
cables.

The configurations are very simple:

--Pair #1--
Cat side:

interface GigabitEthernet5/1
 description Gig-E to GSR #1
 ip address 192.168.0.34 255.255.255.252
end
GSR side:
interface GigabitEthernet6/0
 description Gig-E to Catalyst 4
 ip address 192.168.0.33 255.255.255.252
 no ip directed-broadcast
 negotiation auto
end

--Pair #2-
Cat side:
interface GigabitEthernet5/2
 description Gig-E to GSR #2
 ip address 192.168.0.106 255.255.255.252
end
GSR side:
interface GigabitEthernet6/0
 description Gig-E to Catalyst 4
 ip address 192.168.0.105 255.255.255.252
 no ip directed-broadcast
 negotiation auto
end

we have 3 other catalysts connected to these two GSRs in a similar
fashion (exactly the same) and the GSRs do not show errors.

Any idea why the errors would only show on the GSR side?

Thanks for any advice.
