On downgrade from 9010 and above to 8095, "ve" related interface commands would be removed

When downgrading the switch from 9010 and above to 8095 “ve” related interface commands and L3 configuration would be removed

Issue noticed:

When the user chooses to downgrade from 9010 version and above to 8095 versions in ICX switches, they will notice that the “ve” commands and layer 3 related configurations within the “ve” are wiped out.

Lab output:

If the switch running 9010 version have the below configuration:

interface ve 1

ip address 1.1.1.1 255.255.255.0

no spanning-tree

interface ve 3

ip address 2.2.2.1 255.255.255.0

no spanning-tree

interface ve 5

ip address 3.3.3.1 255.255.255.0

no spanning-tree

When the customer would downgrade from 9010 and above to 8095 versions the configuration would be removed and any configurations included within the ve’s would also be removed.

Reason:

This is an expected behavior. The reason why this is noticed is because on 8095 versions, if we would have to configure “ve ” interface we use command “router-interface ve “ve ID””

Example:

device(config)# vlan 2

device(config-vlan-2)# untag ethernet 1 to 4

device(config-vlan-2)# router-interface ve 2

device(config-vlan-2)# interface ve 2

But from 9010 and above versions the “router-interface ve “ve ID”” command is deprecated and when a “vlan” is created a “ve” with same ID as vlan is also created.

Example:

device(config)# vlan 2

device(config-vlan-2)# interface ve 2

Due to the above changes when you upgrade from 8095 version to 9010 version or above you would not see a problem but when you downgrade from 9010 version and above to 8095 you will notice that since the command “router-interface ve “ve ID”” is not appended to the running configuration the “ve” interface would be completely deleted.

It is recommended to save the configuration as a backup when downgraded from 9010 and above to 8095 and have sufficient downtime to revert back the configurations.

I've experienced that at a customer site.
