To configure load-balancing method for frame distribution. Done globally, not on a port-by-port basis. Default method is src-dst-ip
|
switch (config)# port-channel load-balance [method]
|
|
|
To configure PAgP negotiation (default). Each interface included must be in same unique group (1 to 64)
|
Switch(config-if)# channel- protocol pagp then channel-group [number] mode [on | auto [non-silent] | desirable [ non-silent]]
|
|
|
To configure switches LACP system priority (1 - 65,535, default 32768). Switch with lowest priority makes decisions about the etherchannel makeup. If priority same, lowest MAC
|
switch(config)# lacp system-priority [priority]
|
|
|
To enable LACP negotiation. Each interface included must be in same unique group (1 to 64).
|
Switch(config-if)# channel-protocol lacp then channel-group [number] mode [on | passive | active]
|
|
|
To set the port priority. Interfaces with the lower port priority are active, others held in standby state. If all priorities same, lower port number used.
|
switch(config-if)# port-priority [priority]
|
|
|
To verify the Etherchannel state. Each member port in etherchannel is shown along with flags indicating port state.
|
switch# show etherchannel summary
|
|
|
To verify the etherchannel negotiation mode, and status of each member port in etherchannel
|
switch# show etherchannel port
|
|
|
To show detailed status about each Etherchannel component
|
switch# show etherchannel detail
|
|
|
To verify the etherchannel load-balancing or hashing algorithm
|
switch# show etherchannel load-balancing
|
|
|
To verify how effectively a configured load-balancing method is performing. Info isn't intuitive, but gives idea of each links traffic load relative to others. Also shows time-stamps of etherchannel changes
|
switch# show etherchannel port-channnel
|
|
|
To display a ports configuration. Each port must have same switch mode (access or trunk), native vlan, trunked vlans, port speed and port duplex mode.
|
switch# show running-config interface [type] [mod/num]
|
|
|
To show etherchannel neighbours on each port
|
switch# show [pagp | lacp] neighbor
|
|
|
To see the LACP system ID
|
switch# show lacp sys-id
