Output Fields

Table 1 lists the output fields for the show virtual-chassis vc-path command. Output fields are listed in the approximate order in which they appear.

Table 1: show virtual-chassis vc-path Output Fields

Field Name	Field Description
Hop	The number of hops between the source and destination interfaces.
Member	The Virtual Chassis ID of the member switch that contains the Packet Forwarding Engine for each intermediate hop.
PFE-Device	The number of the Packet Forwarding Engine in each Virtual Chassis member through which a packet passes. Each Packet Forwarding Engine is the next hop of the preceding Packet Forwarding Engine.
Interface	The name of the interface through which the Packet Forwarding Engines are connected. The interface for the first hop is always the source interface and the interface for the last hop is always the destination interface. For intermediate hops, the Interface field denotes the Packet Forwarding Engines through which the packet passes on its way to the next hop.
