Command
Mandatory
or Optional
Not Configured on Peer
(Peer receives MAC
from local switch)
Not Configured on Peer
(MAC ingresses on peer switch
MCLAG aggregate)
UNP Commands
unp linkagg Mandatory Peer drops packet. Peer learns MAC; no UNP classifi-
cation.
unp name Mandatory Peer drops packet. Peer learns MAC based on the peer
MCLAG aggregate configuration.
unp linkagg mac-
authentication
Mandatory Peer learns MAC. MAC is not authenticated but may
get classified into different UNPs
on each switch (local and peer).
unp linkagg mac-
authentication pass-alternate
Mandatory Peer learns MAC. MAC is authenticated but will not
get learned in pass alternate UNP
and may get classified into different
UNPs on each switch (local and
peer).
unp linkagg classification Mandatory Peer learns MAC. MAC is not classified but may get
assigned to a different UNP on each
switch (local and peer).
unp linkagg trust-tag Mandatory Peer learns MAC. If tagged packet is not authenti-
cated and/or classified, then the
tagged packet may get filtered.
However, if the MAC ingresses on
the local switch first, then the MAC
is learned as forwarding on the
tagged packet.
unp linkagg default-unp Mandatory Peer learns MAC. If MAC is not authenticated and/or
classified, MAC is filtered due to
missing default UNP.
unp classification (rules) Mandatory Peer learns MAC. MAC may get classified into differ-
ent UNPs on each switch (local and
peer).
unp auth-server-down unp Mandatory Peer learns MAC. MAC may get classified into differ-
ent UNPs on each switch (local and
peer) and no relearning of MAC
occurs when server comes back up.
Source Learning Commands
no mac learning dynamic Optional N/A MAC flush is propagated to the
peer switch, so performing this
command is not necessary on the
peer.
