Hello,

can you post an output of some of the interfaces:

show interfaces brief

show media

show lag brief (if any)

Thanks,

Jörg

Hi Jeorgkost,

I just already enabled both interfaces of connected MLX and it went up.

Here is my first configuration.

Can I verify if it Is successful LAG? how can I see the connected peer?

In VDX I can see by show LLDP neighbor, and in Summit by show fdb

Regards,

Sazon

Hello Sazon,

I think you are looking for

show lacp lag_id 10

If you also want to run LLDP, you need to enable it first:

(config)#lldp ?
  advertise                    Control advertising of information
  enable                       Enable LLDP on interfaces, SNMP notifications
  max-neighbors-per-port       Specify the maximum number of neighbors per port
  max-total-neighbors          Specify the maximum number of total neighbors
  reinit-delay                 Specify the minimum time between port
                               reinitializations
  run                          Enable LLDP globally
  snmp-notification-interval   Specify the minimum time between
                               lldpRemTablesChange traps
  transmit-delay               Specify the minimum time between LLDP
                               transmissions
  transmit-hold                Specify the hold time multiplier for transmit TTL
  transmit-interval            Specify the interval between regular LLDP
                               transmissions

Regards.

Hi Joergkost,

After I “lldp run” command. I can now see the connected device and the LAG.

Thank you so much.
