Differences in configuring MCT for the switch and router image

There are some differences in the MCT configuration for the switch image versus the router image:

• On a switch image, STP is by default enabled for all the VLANs; however, for MCT, Layer 2 protocols such as STP and RSTP should not be enabled on the session VLAN. Therefore, STP must be disabled explicitly for the session VLAN. STP is automatically disabled in the router image.
• Virtual Ethernet (VE) cannot be configured on a session VLAN in a switch image, but an IP address is needed for the cluster devices to communicate via CCP. Therefore, in a switch image, the configured management IP address is used to establish communication between the cluster devices.
• The management IP addresses in each of the cluster devices should be configured in the same subnet. If the IP addresses are in different subnets, ARP does not resolve the addresses, and MCT may not work. ARP for the peer cluster devices is always learned on the ICL port or trunk, so any management traffic between the two devices always goes through the ICL ports.
