Multi-Chassis Trunking Overview
22
Unicast traffic from a client through a CCEP to a CEP
1. Traffic originates at the client.
2. Because the link between the client switch and the MCT cluster is a trunk, the traffic travels
over one physical link. In the example in Figure 97, the traffic travels over the link towards
cluster device 2. The traffic enters the MCT cluster through the CCEP of cluster device 2.
3. Depending on the destination, the traffic may pass over the ICL link to the other cluster device.
In the example in Figure 97, the destination is on cluster device 1, so the traffic is forwarded
out to the ICL port.
4. The traffic passes out to the destination.
Refer to Figure 97.
