In that name, vcp-255 indicates that the interface is a VCP,
and is the port number. The
0
a positive number ID assigned to the LAG formed by the Virtual Chassis. If no LAG is
formed, the value is –1 .
NOTE: Each switch assigns the trunk IDs to its local interfaces. As a result,
the pair of interfaces that form one end of a LAG on one switch will have the
same trunk ID, and the pair of interfaces that form the other end of the LAG
will have the same trunk ID, but the trunk IDs on either end of the LAG might
be different. For example, in Figure 23 on page 971, the uplink VCPs
on SWA-0 form a LAG with the network VCPs
1/3
Uplink VCPs 1/2
and on SWA-4 both have trunk ID
0/20 0/21
between the switches because SWA-0 assigns the trunk IDs for its local
uplink VCPs and SWA-4 assigns the trunk IDs for its local VCPs.
