How do I view port channel interfaces?
How do I view port channel interfaces?
Use the command, show port-channel summary, to verify the number of port-channels already configured. You can have a maximum of 256 port channels on the Cisco Nexus 1000V. Use this procedure to force the physical interface to take on the characteristics of the port channel.
What is port channel interface?
A port channel interface is a virtual interface that serves a corresponding channel group and connects to a compatible interface on another switch to form a port channel. Port channel interfaces can be configured and used in a manner similar to Ethernet interfaces.
How do you check EtherChannel?
Verifying and Troubleshooting EtherChannel When several port channel interfaces are configured on the same device, use the show etherchannel summary command to simply display one line of information per port channel.
What is Po1 Cisco switch?

How do port channels work?
Port channels aggregate multiple physical interfaces into one logical interface to provide higher bandwidth, load balancing, and link redundancy. channel. If a link goes down in a port channel, the upper protocol is not aware of it. To the upper protocol, the link is still there, although the bandwidth is diminished.
Which command displays the etherchannel bundle output?
The show etherchannel command gives you an overview of our EtherChannel. You can see the protocol and interfaces we use, and it tells us whether the logical interface is up.
What do you call a port channel interface?

Why is the show config interface command useful?
This command is useful because it reduces IOS’s output to just show you the interface information.
