5.4.4 IPL Interface
The link connecting between two MLAG peer switches is referred as the Inter Peer Link (IPL). This link
should be configured as an LACP port channel. It can have as many member ports as supported by the
switch model.
Only the primary switch among the peers participates in spanning tree protocol.
Follow the steps below to configure the IPL interface.

be created on both peer switches with the same port channel number.
