This document describes the best practices on how to configure Viptela vEdges at the time of Customer Maintenance Window, in order to prevent any unwanted outages due to the configuration changes that are made, which might result in unintended consequences.
There are no specific requirements for this document.
This document is not restricted to specific software and hardware versions.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.
When the customer deployment windows, it is always recommended to configure with “exclusive” option, so that you can verify the
configuration, prior to the commit.
This allows for any un-intended configuration, not to go into production that might cause any issues. These could manifest in the
form of losing connectivity to the device or when a wrong policy is applied. This allows rollback of the configuration to a (prior)
It is always recommended to come up with a configuration prior to the maintenance window and test in the laboratory before you apply on the production router.
These are the configuration options that are allowed on vEdges.
vEdge# config ? Possible completions: exclusiveno-confirmsharedterminal|<cr>
Configure with the exclusive command.
vEdge# config exclusive Entering configuration mode exclusive Warning: uncommitted changes will be discarded on exit vEdge(config)#
This is the message that appears when the commit command is not executed.
vEdge(config)# vpn 1 vEdge(config-vpn-1)# ip route 18.104.22.168/32 null0 vEdge(config-vpn-1)# commit confirmed 1 Warning: The configuration will be reverted if you exit the CLI without performing the commit operation within 1 minutes.
vEdge# Message from system at 2019-07-08 01:07:13... confirmed commit operation not confirmed by admin from cli configuration rolled back vEdge#
vEdge# config exclusive Entering configuration mode exclusive Warning: uncommitted changes will be discarded on exit vEdge(config)# vpn 1 vEdge(config-vpn-1)# ip route 22.214.171.124/32 null0 vEdge(config-vpn-1)# commit confirmed 1 Warning: The configuration will be reverted if you exit the CLI without performing the commit operation within 1 minutes. vEdge(config-vpn-1)# Message from system at 2019-07-08 21:07:37... confirmed commit operation not confirmed by admin from cli configuration rolled back vEdge(config-vpn-1)#
Once you are sure all is in place, you can execute the command commit.
vEdge(config-vpn-1)# commit Commit complete. Configuration is now permanent. vEdge(config-vpn-1)#
For the commit confirmed option, it is recommended to have about 5 to 10 minutes in order to validate the configuration that was put in place. Here, 1 minute is used as an example.
Use this section in order to confirm that your configuration works properly.
Execute show running-config or appropriate config-sub-block command.
Here is an example of validation:
vEdge# show running-configvpn 1 ip vpn 1 ip route 126.96.36.199/32 null0 ! vEdge#
There is currently no specific troubleshooting information available for this configuration.
