MLAG IPL link

Good Morning

I configured two 1410 switch with MLAG using the doc

https://mymellanox.force.com/mellanoxcommunity/s/article/how-to-configure-mlag-on-mellanox-switches#jive_content_id_MLAG_Interface. I read that all VLANs are open on this port. There is no need to configure that, as once an interface is mapped as IPL all the VLANs are open on this port.

in my config for PO1 (IPL) are used port 1/49 and 1/50

sw-amb-40G-u39 [amb-vip: master] # show mlag

Admin status: Enabled

Operational status: Up

MLAG IPLs Summary:


ID Group Vlan Operational Local Peer Up Time Toggle Counter

Port-Channel Interface State IP address IP address


1 Po1 4001 Up 11.0.0.39 11.0.0.40 0 days, 12:08:19 3

If I run command show vlan I don’t see any VLAN on ports that belongs to PO1 ???. It is normal ???

sw-amb-40G-u39 [amb-vip: master] # show vlan


VLAN Name Ports


1 default Eth1/3, Eth1/4, Eth1/5, Eth1/6, Eth1/9,

II see that PO1 in in trunk mode

sw-amb-40G-u39 [amb-vip: master] # show interfaces port-channel 1

Po1:

Admin state : Enabled

Operational state : Up

Switchport mode : trunk

it is normal that the ports that belongs to PO1 re in access mode ??
