[c-nsp] Strange problems with Cisco ASR1002 RP1

[Olivier CALVANO]

Hi

I have a very strange problem with Cisco ASRs that I have never had before.

I have a chassis equipped with an ESP20 card, everything seems to work
because no message in the logs but impossible to ping it.

The interfaces are UP on each side, the IPs are ok.on the ASR I can not
even ping the IP assigned to the interface (it does not even ping his ip).

I change the SFP, no change
I change the ESP, no change
I change the chassis, no change
I change the port and the SFP on the other router or it is connected, no
change
I change the IOS version, no change

the port on the other router works without problems because tested with a
cisco 7201

would I have missed something in an activation? the config could not be
simpler, realized with the command setup

thanks for your suggestion
Olivier

Hi,

Can you share the output of ‘show int <int name>’ ? It could be wedge interface. Check the input queue size and packets within. If the packets are more than the max size it is wedge interface.
