Guidelines for LACP for Gigabit Interfaces Configuration
Port channel interfaces that are configured improperly with LACP are disabled automatically to avoid network
loops and other problems. To avoid configuration problems, observe these guidelines and restrictions:
•
Every port added to a port channel must be configured identically. No individual differences in
configuration are allowed.
•
Bundled ports can be configured on different line cards in a chassis.
•
Maximum transmission units (MTUs) must be configured on only port channel interfaces; MTUs are
propagated to the bundled ports.
•
QoS and committed access rate (CAR) are applied at the port level. Access control lists (ACLs) are
applied on port channels.
•
MAC configuration is allowed only on port channels.
•
MPLS IP should be enabled on bundled ports using the mpls ip command.
•
Unicast Reverse Path Forwarding (uRPF) should be applied on the port channel interface using the ip
verify unicast reverse-path command in interface configuration mode.
•
Cisco Discovery Protocol enable is not supported on the port channel interface.
•
All LAN ports in a port channel should be enabled. If you shut down a LAN port in a port channel, the
shutdown is treated as a link failure and the traffic is transferred to one of the remaining ports in the port
channel.
