Assume we have a Data Room switch providing access to servers. This switch is connected to a Distribution switch which aggregates traffic from several user access switches. If we connect the two switches together with a single 1Gbps interface, then it could potentially be a bottleneck to traffic from users to servers especially for high-volume applications.

With Etherchannel, we can bundle together up to 8 interfaces to form a single logical link Port-Channel and traffic is load-balanced between all interfaces. In our example above, 4x1Gbps interfaces were bundled together thus forming a 4Gbps pipe from users to servers.

Cisco Switch EtherChannel Configuration – LACP – PAgP

This increases bandwidth but also enhances redundancy between the switches. If you connect the interfaces as shown above without configuring EtherChannel, then a Spanning-tree loop will be detected and 3 out of 4 links will be blocked by Spanning-Tree Protocol.

By configuring Etherchannel, the bundle is considered as a single logical interface and there are no spanning tree loops. There are two Etherchannel protocols. These protocols manage the channel establishment between the switches:.

Each protocol listed above has three modes of operation which dictate if the switch will actively seek to form an Etherchannel link or will wait for the other end to form the link. Yes it will work also without trunk on the port-channel.

The trunk is useful to pass vlans between switches. Your email address will not be published. This site uses Akismet to reduce spam.
