show vpex ports

show vpex ports {ports_list}

Description

Shows information about the bridge port extender (BPE) attached to the specified cascade ports.

Syntax Description

vpex Specifies Virtual Port Extender (VPEX).
ports Specifies the cascade port attached to the BPE.
port_list Specifies the cascade port attached to the BPE.

Default

If you do not specify any ports, information for all cascade ports appears.

Usage Guidelines

The following information appears:
  • Port number
  • Cascade port
  • Ext slot
  • Slot identifier for the attached BPE
  • Port state
  • Link state
  • PECSP MAC address
  • PE MAC address
  • CSPOpen and Loc (local) Rem (remote) status— a value of 1 indicates that a CSP Open request has been sent and acknowledged.
  • CSP role flags— when using two CBs with MLAG, the flags indicate which node is performing the role of master (M) and backup (B)

In a redundant CB configuration, the M flag in the output of this command indicates the CB occupying the master role.

Example

The following example shows information for BPEs attached to all cascade ports:

 # show vpex ports

#       Port    Slot State  State  MAC Address        MAC Address        Loc Rem   Flags
