How do I create a port channel on a Cisco switch?
You create a port channel by bundling compatible interfaces. You can configure and run either static port channels or port channels running the Link Aggregation Control Protocol (LACP). Any configuration changes that you apply to the port channel are applied to each member interface of that port channel.
What is port channel configuration?
Port Channel Configuration. A port-channel or channel group, is an aggregation of multiple physical interfaces that creates a logical interface. A port-channel bundles up to four individual interfaces into a group to provide increased bandwidth and redundancy.
How do I configure a Layer 2 port channel?
When configuring Layer 2 EtherChannels, follow these guidelines:
- Assign all ports in the EtherChannel to the same VLAN, or configure them as trunks.
- If you configure an EtherChannel from trunk ports, verify that the trunking mode (ISL or IEEE 802.1Q) is the same on all the trunks.
How do I check my port channel settings?
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 on Cisco switch?

What is port channel vs EtherChannel?

Do port channel numbers need to match?
The Port-Channel interface numbers are locally-significant only. On the 2960, the number can be anything between 1 and 6, and they do not have to match end to end. If it is possible, use the same number on both sides of a port-channel so that coordinating troubleshooting is less complicated.
