MCT and VLANs
MCT relies on the following VLAN types:
• Session VLAN: Provides the control channel for CCP. Brocade recommends keeping only ICL ports
in the session VLAN. A virtual interface must be configured on the session VLAN for the router
image.
• Keep-alive VLAN: Provides a backup control path if the ICL goes down (optional, but strongly
recommended).
• MCT VLAN: Serves the customer data traffic. An ICL must belong to every MCT VLAN to provide a
data path between two cluster devices. When an ICL is added to a VLAN, it becomes an MCT
VLAN.
Cluster client automatic configuration
Client configuration includes setting the client name, client RBridgeID (unique identification for each
client), client interface (CCEP), and deployment settings on both MCT cluster devices. With up to 150
clients per cluster, manual configuration can take a considerable amount of time.
Cluster client automatic configuration saves the time that would be required to complete the entire
configuration manually.
The following limitations apply to cluster client automatic configuration:
