Setting Lacp System Priority And Port Priority - Cisco ASR 920 Series Configuration Manual Ethernet Router

Setting LACP System Priority and Port Priority

Command or Action
Step 7
show running-config interface port-channel group-number
Example:
Device# show running-config interface port-channel

Step 8 show etherchannel summary
Example:
Device(config)# show etherchannel summary
For the LACP 1:1 redundancy feature, both ends of the EtherChannel must be enabled.
Note
Example
This example shows how to configure an LACP EtherChannel with 1:1 redundancy. Because Fast Ethernet
port 5/6 is configured with a higher port priority number (and therefore a lower priority) than the default of
32768, it will be the standby port.
