Interface Te 1 not compatible with Interface Te 2 Storm-control Action

[Dimitri.F]

Hello,

I got a problem on a switch, i have an interface TE who are in a suspend mode.
When i check the configuration on Po and on both interface, the configuration is the same...

L2 Switch error log : Te2/1/4 is not compatible with Te1/1/3 and will be suspended (Storm-control Action of Te2/1/4 is SHUTDOWN,SEND TRAP, Te1/1/3 is SEND TRAP,)

L3 Switch error log : Te2/0/3 suspended: LACP currently not enabled on the remote port.

See the configuration below :

Hello @Dimitri.F ,

try the following:

shutdown both member links and po1 interface on L2 switch

remove storm-control configuration ( disable it ) on both member links and on the po1

unshut the port-channel

unshut the member links ( ideally at the same)

Check what happens.

The affected port Te2/1/4 may be influenced by some near port configuration check the storm control settings on ports Te2/1/x this might explain what you see.

Your L2 switch is clearly a stack

can you post

show version

Hope to help

Giuseppe

@Giuseppe Larosa,

Thanks for your reply, i have some users who are log on this switch, i could only disable the storm-control configuration after 8 PM tonight.

See the show version below :

Switch Ports Model SW Version SW Image Mode
------ ----- ----- ---------- ---------- ----

  4 52 WS-C3650-48PD 03.06.03E cat3k_caa-universalk9 INSTALL

i haven't post all the reply, i  think  that you're looking for the IOS version from the stack, if you need something more specifically i will post it again

Thanks for your help.

Kind regards, Dimitri.

Hello @Giuseppe Larosa,

I disable the storm control on the Port-channel, each Te port and on each cisco stack (L2 + L3).

I got the same problem :

Sep 22 13:35:50.605 PARIS: %EC-5-L3DONTBNDL2: Te2/0/3 suspended: LACP currently not enabled on the remote port.
Sep 22 13:36:32.585 PARIS: %LINK-3-UPDOWN: Interface TenGigabitEthernet2/0/3, changed state to down
Sep 22 13:36:33.075 PARIS: %DTP-5-NONTRUNKPORTON: Port Te2/0/3 has become non-trunk
Sep 22 13:37:15.105 PARIS: %LINK-3-UPDOWN: Interface TenGigabitEthernet2/0/3, changed state to up
Sep 22 13:37:15.596 PARIS: %DTP-5-TRUNKPORTON: Port Te2/0/3 has become dot1q trunk
Sep 22 13:37:22.886 PARIS: %EC-5-L3DONTBNDL2: Te2/0/3 suspended: LACP currently not enabled on the remote port.

I try to force the lacp on each Te with : channel-protocol lacp but i still have the problem...
