The

configuration with the member IDs and mastership priority values. It also displays the
neighbor members with which each member is interconnected. This output shows that
SWA-2 has been assigned member ID 2 and has the default mastership priority value
128. Because the mastership priority is lower than the mastership priority of the other
members, SWA-2 functions in the linecard role. You can continue to add more member
switches, following the same procedure. It is possible to have multiple members in linecard
roles with the same mastership priority value.
Verifying That the VCPs Are Operational
Verify that the dedicated VCPs interconnecting the member switches are operational.
List the VCP interfaces on the Virtual Chassis configuration.

Virtual Chassis configuration. In this case, no VCP uplinks have been configured. However,
the VCP interfaces are automatically configured and enabled when you interconnect
member switches using the dedicated VCPs. There are two dedicated VCPs on the rear
panel of each EX4200 switch. We recommend that you interconnect the member switches
using both VCPs for redundancy. The VCP interfaces are identified simply as
. The number is the same as the member ID.
