Verifying Virtual Chassis Ports in an EX8200 Virtual Chassis
Purpose
Verify that the Virtual Chassis ports (VCPs) in the EX8200 Virtual Chassis are properly configured. This task is particularly important as a method of confirming the user-configured VCP connection between two EX8200 switches.
Action
Verify the type, status, speed, and neighbor ID and interface of each VCP on an EX8200 switch or an XRE200 External Routing Engine:
user@external-routing-engine> show virtual-chassis
vc-port member 0member0: -------------------------------------------------------------------------- Interface Type Trunk Status Speed Neighbor or ID (mbps) ID Interface Slot/PIC/Port vcp-0/0 Dedicated -1 Up 1000 8 vcp-1/1 vcp-0/1 Dedicated -1 Up 1000 9 vcp-1/1 3/0/2 Configured -1 Up 10000 1 vcp-4/0/2 3/0/3 Configured Absent 3/0/4 Configured Absent 3/0/5 Configured Absent 3/0/6 Configured Absent 3/0/7 Configured Absent
Meaning
Members 0 through 7 in an EX8200 Virtual Chassis are reserved for EX8200 switches, so we know this output from member 0 shows the VCP connections from an EX8200 member switch.
The output shows that the switch has a dedicated VCP connection to each external Routing Engine—member IDs 8 and 9, which are always external Routing Engines. These links are dedicated because they are connections to an external Routing Engine.
The output also shows a VCP link between two EX8200 switches (member 0 and member 1). VCP links between EX8200 member switches must be user-configured, and the Configured Type output is a result of this user configuration. This VCP link is from interface vcp–3/0/2 on the switch to interface vcp–4/0/2 of the switch acting as member 1.
Trunk ID -1 is used to indicate a link is not part of a link aggregation group (LAG). This output shows that no links in this configuration are part of a LAG.
