Cisco Port Channel




A Port Channel bundles up to eight individual interfaces into a group to provide increased bandwidth and redundancy. Port channeling also load balances traffic across physical interfaces.

A Static port channels has no associated protocol, for a simplified configuration. Enable Link Aggregation Control Protocol (LACP) for more efficient use of the port channel. LACP is defined in IEEE 802.3ad.

To Enable LACP:

sw(config) # feature lacp

Creating a Port Channel, channel number 1 to 4096, and adding a Ports:

sw(config) # interface port-channel 3
sw(config-if) # interface ethernet 1/5-6
sw(config-if-range) # switchport mode trunk
sw(config-if-range) # channel-group 3 mode active
