vlb-name name-string

Displays the virtual link extension


Displays the ID assigned to the VLE.

node-1 fabric-node name

Displays the name of VLE node 1.

node-2 fabric-node name

Displays the name of VLE node 2.

node-1-port node-1-port-number

Displays the node-1 port that is part of VLE.

node-2-port node-2-port-number

Displays the node-2 port that is part of VLE.

Formatting Options

format fields-to-display

Display output using a specific parameter. Use all to display all possible output.

parsable-delim character

Display output formatted for machine parsing using a specified delimiter.


Display output in ascending order.


Display output in descending order.

show dups

Display duplicate entries in the output.

layout vertical|horizontal

Format the output in a vertical or horizontal layout.

show-interval seconds-interval

Repeat the show command at a specified interval.


Display column headers or not.

limit-output number

Limit the display output to a specific number of entries.


Display the number of entries in the output. This is useful with vRouter show commands.


Display full values in the output instead of scaled approximate values.


Displays full value instead of scaled approximate value.


Aggregate output by specific parameters. If sum-by fields are specified, records that have the same value in sum-by fields are combined and displayed as one aggregate record. NOTE: This option is only available for show commands that collect statistics such as connection-stats-show.

Defaults   None.

Access   CLI

History   Command introduced in Version 2.5.4.


Provides a mechanism for link state tracking between two ports of two switches in the same fabric for Virtual Link Extension (VLE). When a VLE is created between two physical ports of two switches, the VLE remains up as long as both physical ports are in the state link up.

When VLE tracking is created on a trunk port, the VLE stays up as long as at least one port in the trunk is link up and the remote port is also up. When the last trunk member goes link down, the VLE is brought down. When you configure VLE tracking on a trunk port, you cannot configure tracking on individual trunk members.

VLE tracking helps achieve VLE high availability on Netvisor nodes and avoid the need on the client side to run LACP for link up/down detection.

Examples  To display virtual link extension status, use this command:

CLI network-admin@switch > vle-show

name       node-1   node-2   node-1-port node-2-port status tracking

---------- -------- -------- ----------- ----------- ------ --------

Test1       mynode1 mynode2   11          11          up     yes
