FS#3667 — FS#7608 — sup2t TCAM programming

Attached to Project— Network
Incident
Whole Network
CLOSED
100%
In the SY1/2 version there is a bug in
the TCAM programming in the different cards.
The router is installing a route
and then copy it in each TCAM of each card.
Sometimes this copy is not done correctly !!


This gives this looping traceroute :

We see the ip of ams-1-6k which is tied to
the port channel of the card 3. We are reloading the card 3.

ams-1-6k-SUP2T(config)#no power enable module 3


We still see the problem on the card 5

10 minutes:
ams-1-6k-SUP2T(config)#power enable module 3
5 minutes:
ams-1-6k-SUP2T(config)#no power enable module 5


We still see the problem on card 1

10 minutes:
ams-1-6k-SUP2T(config)#power enable module 5
5 minutes:
ams-1-6k-SUP2T(config)#no power enable module 1

le probleme on voit encore sur la carte 4

10 minutes:
ams-1-6k-SUP2T(config)#power enable module 1
5 minutes:
ams-1-6k-SUP2T(config)#no power enable module 4

Card 3 again !

10 minutes:
ams-1-6k-SUP2T(config)#power enable module 4

Some ports were not remounted.
We must interrupt the cards during 10 minutes.
A stupid bug on the opticals.
We have to change them as soon as possible.
