Chapter 6 Configuring Fast EtherChannel and Gigabit EtherChannel Configuring EtherChannel Using LACP Specifying the System Priority Note Although the set lacp-channel system-priority command is a global option, it applies only to modules on which LACP is enabled; it is ignored on modules running PAgP. The system priority value must be a number in the range of 1-65,535, where higher numbers represent lower priority. The default priority is 32,768. To specify the system priority, perform this task in privileged mode: Task Specify the system priority. Command set lacp-channel system-priority value This example shows how to specify the system priority as 20,000: Console> (enable) set lacp-channel system-priority 20000 LACP system priority is set to 20000 Console> (enable) Use the show lacp-channel sys-id command to display the LACP system ID and system priority. Specifying the Port Priority The port priority value must be a number in the range of 1-255, where higher numbers represent lower priority. The default priority is 128. To specify the port priority, perform this task in privileged mode: Task Specify the port priority. Command set port lacp-channel mod/ports port-priority value This example shows how to specify the port priority as 10 for ports 1/1 to 1/4 and 2/6 to 2/8: Console> (enable) set port lacp-channel 1/1-4,2/6-8 port-priority 10 Port(s) 1/1-4,2/6-8 port-priority set to 10. Console> (enable) Use the show lacp-channel group admin_key info command to display the port priority. Specifying an Administrative Key Value Note When the system or module configuration information stored in NVRAM is cleared, the administrative keys are assigned new values automatically. For modules, each group of four consecutive ports, beginning at the 1st, 5th, 9th and so on, are assigned a unique administrative key. Across the module, ports must have unique administrative keys. After NVRAM is cleared, the channel mode of the ports is set to "passive." 78-15486-01 Catalyst 4500 Series, Catalyst 2948G, Catalyst 2980G Switches Software Configuration Guide-Release 8.1 6-19
