vle-show
This command displays a virtual link extension status.
Syntax vle-show
|
vle-name name-string |
Displays the virtual link extension |
|
id |
Displays the ID assigned to the VLE. |
|
vnet vnet-name |
Specify the vNET name. |
|
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. |
|
status unknown|remote-down| |
Displays the VLE status. |
|
tracking|no-tracking |
Displays tracking status as enabled or disabled. |
|
ports-state enable|disable |
Displays the ports-state. override is the default setting which means that each individual port state configuration takes precedence. disable means that both vLE ports get disabled together and this option takes precedence over each individual port state. enable means that both vLE ports get enabled and this option takes precedence over each individual port state. |
|
create-time date/time: yyyy-mm-ddTHH:mm:ss |
The time at which the vLE is created. |
|
elapsed-time duration: #d#h#m#s |
The time elapsed since the vLE was created. |
|
up-time duration: #d#h#m#s |
Time since the last instance at which the vLE came online. |
Defaults None.

Usage
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.
