Cisco C2960LSM switc not forwarding packets with "Do not fragment' set

johnchrapkowski · ‎12-20-2023

We've got a C2960 LSM switch that won't allow traffic that has the 'do not fragment' flag (specifically ssh) to one network. I can ping/traceroute fine, but not ssh. It's a LSM so it doesn'thave command line, so adjusting MSS isn't possible as far as I can tell. Any other ideas?

can you post show version and show run to help us to see what is wrong ?

from what device you trying to SSH ?

have you done the config :

enable SSH V2 .
adding ip domain-name
generating crypto key RSA 1024

I do not have experience with the 2960L switches. The documentation seems to indicate that it does have some CLI capabilities. Can you tell us what commands are available in CLI? Are you able to access the web management of the switch? If so what does it allow you to do?
