VLAN and MLT Upgrade Considerations

VLAN or MLT Name Uses all Numbers

Representational State Transfer Configuration Protocol (RESTCONF) does not allow VLAN or MLT names that contain all numbers. Beginning with VOSS 8.0, the VLAN or MLT name cannot use all numbers. If, in a release prior to 8.0, you configured a name that was all numbers, see the following table to understand the impact of upgrading to a newer release.

Target upgrade release Impact after upgrade

VOSS 8.0.5.x, 8.0.6.x, or 8.0.7.x

The system prepends VLAN- or MLT- , and appends -01, to the name during the upgrade. For example, the VLAN name 222 becomes VLAN-222-01.

VOSS 8.0.8 and later

If you plan to enable RESTCONF, you must check interface names for invalid special characters or conflicts, and make necessary modifications manually. For information about how to check interface names, see the RESTCONF content in Representational State Transfer Configuration Protocol (RESTCONF).

VOSS 8.1 or 8.1.1.x

The system prepends VLAN- or MLT- , and appends -01, to the name during the upgrade. For example, the VLAN name 222 becomes VLAN-222-01.

VOSS 8.1.2 and later

If you plan to enable RESTCONF, you must check interface names for invalid special characters or conflicts, and make necessary modifications manually. For information about how to check interface names, see the RESTCONF content in Representational State Transfer Configuration Protocol (RESTCONF).
