CAUTION:
•
Do not configure any Layer 3 features, such as MPLS and VPN, on a port to be added to a Layer 3
aggregation group. Remove any Layer 3 feature configured on a port before adding it to a Layer 3
aggregation group.
•
After adding a port to a Layer 3 aggregation group, configure Layer 3 features on the aggregate
interface instead of on the member ports. If you configure any Layer 3 feature mistakenly on a member
port, remove the Layer 3 feature configuration from the member port and then run the
shutdown
and
undo shutdown
commands on the aggregate interface.
•
Removing an aggregate interface also removes the corresponding aggregation group. At the same
time, all member ports leave the aggregation group.
•
You cannot change the working mode (bridging or routing) of the member ports in an aggregation
group.
•
You can assign only ports on the same type of cards to an aggregation group when the router works in
hybrid mode. For example, after assigning ports on an SPE card to an aggregation group, you cannot
assign ports on an SPC card to the aggregation group.
Configuring a static aggregation group
NOTE:
To guarantee a successful static aggregation, make sure that the ports at both ends of each link are in the
same aggregation state.
