VDX/MLX showing connected devices details

Sazon — Wed, 08 Jul 2020 07:50:42 GMT

Hi Sir,Mam,

In Extreme Summit switches we can show the connected devices by

#show fdb

#show iparp

What is the command in VDX switches and in MLXe router?

Thank you,

Sazon

hi Sazon,

Does the ‘show mac’ and ‘show arp’ output in the VDX and MLX give you the information you’re looking for?

Hi Truyen,

Mac-address cannot see

TE 1/0/17 and 1/0/18 is in port channel but cannot see also in interface status

With IP Arp there are options but cannot see also IP address of end devices unlike in summit iparp

If the devices are in a port-channel, the MAC will show as being learned on the port-channel interface instead of the individual interfaces.

If you do ‘show mac’, do you see the MAC on the port-channel?

‘show ip arp’ will only have the entries, if the VDX is doing L3.

Hi Truyen,

It doesn’t show the Te 1/0/17 and Te 1/0/18

hi Sazon,

Once the interfaces are bound into the port-channel, only the logical interface (port-channel) will be reference in the outputs.
