EtherChannel - Troubleshooting on Cisco IOS Switches

To troubleshoot EtherChannel issues on Cisco IOS switches, it is essential to verify the status and configuration of the involved interfaces. Here are some key commands to use:

  1. show etherchannel 1 detail: Provides detailed information about the EtherChannel group.
  2. show running-config interface po1: Displays the running configuration for the PortChannel interface.
  3. show running-config interface gigabitethernet0/0: Shows the running configuration for the GigabitEthernet interface 0/0.
  4. show running-config interface gigabitethernet0/1: Shows the running configuration for the GigabitEthernet interface 0/1.

By comparing the output of these commands on both devices, you can identify discrepancies or misconfigurations that may be causing issues.
