Syntax

show vsx brief [vsx-peer]

Description

Displays the brief VSX status.

Operator (>) or Manager (#)

Parameters

[vsx-peer]: Shows the output from the VSX peer switch. If the switches do not have the VSX configuration or the ISL is down, the output from the VSX peer switch is not displayed.

Authority

Operators or Administrators. Users without administrator authority can execute this command from the operator context (>) only.

Usage

The show vsx brief command displays the ISLP device protocol states under the "Device State" heading.

ISLP device protocol states
Device state	Definition
Peer-Established	The VSX switch is in a steady state. VSX LAGs are up.
Sync-Primary	ISL connectivity to the peer VSX switch is restored, and the VSX switch is syncing states to the peer VSX switch. VSX LAGs are up.
Sync-Secondary	ISL connectivity to the peer VSX switch is restored, and the VSX switch is learning states from the peer VSX switch. VSX LAGs are down.
Sync-Secondary-Linkup-Delay	The VSX switch has learned its states from the peer VSX switch, and the VSX switch is monitoring for hardware to be programmed. VSX LAGs are down.
Split-System-Primary	The VSX switch has lost ISL connectivity to the peer VSX switch. The VSX switch is operating as the primary VSX switch. VSX LAGs are up.
Split-System-Secondary	The VSX switch has lost ISL connectivity to the peer VSX switch. The VSX switch is operating as the secondary VSX switch. VSX LAGs are down.
Waiting-For-Peer	The VSX switch is waiting for connectivity to the peer VSX switch.

Example

Displaying the brief VSX status for the switch you are logged into:

vsx-primary# show vsx brief
ISL State                              : In-Sync
Device State                           : Peer-Established
Keepalive State                        : Keepalive-Established
Device Role                            : primary
Number of Multi-chassis LAG interfaces : 2

Displaying the brief VSX status for the peer (secondary) switch while entering the command on the primary switch:

vsx-primary# show vsx brief vsx-peer
ISL State                              : In-Sync
Device State                           : Peer-Established
Keepalive State                        : Keepalive-Established
Device Role                            : secondary
Number of Multi-chassis LAG interfaces : 2

Displaying the brief VSX status for the peer (primary) switch while entering the command on the secondary switch:

vsx-secondary# show vsx brief vsx-peer
ISL State                              : In-Sync
Device State                           : Peer-Established
Keepalive State                        : Keepalive-Established
Device Role                            : primary
Number of Multi-chassis LAG interfaces : 2
