Link Aggregation Group (LAG)

Link Aggregation allows administrators to assign multiple physical links to one logical link. This logical link functions as a single, higher-speed link, providing dramatically increased bandwidth.

Relevant configuration

(switch (config) #) Create and configure the LAG interface:

interface port-channel 1

(switch (config interface port-channel 1) #) Exit port-channel context:

exit

(switch (config) #) Associate member links with the LAG interface:

interface IFACE
channel-group 1 mode on

(switch (config interfaces ethernet 1/7)#) Enable LACP in LAG:

lacp rate fast

Show commands to validate functionality

show interface port-channel

Expected results

  • Administrators can create and configure a LAG
  • Administrators can add ports to a LAG
  • Administrators can configure a LAG interface
