LLDP does not disable in 3.1

Products ePMP
#1

We noticed a wierd increase in traffic on our network and traced it down to discovery protocol responses. It turns out in 3.1 LLDP can not be disabled via gui or cli. A roll back to 2.6.2 fixes the issue. Has anyone else seen this problem ?

update: it appears that 3.2 increases the problem, in 3.1 responses are every 5-10 seconds, but in 3.2 responses are every 1-2 seconds.

Hi Ben Backus,

Could you execute and attach next commands:

on ePMP device CLI:
  show lldp-neighbors

on directly connected PC:
  lldpctl

Thanks.

#3

running the neighbors command results in this

Officese-camb>show lldp-neighbors

It appears it does not see any neighbors

but our firewall tells a different story

Also the lldpctl command is not active in the shell from what i can tell.

Has anything come  of this?

#5

If anyone else has this problem it is fixed by setting: System "MAC-Telnet-Access" is disabled.
