- If you enabled LLDP TLVs in Cumulus Linux 5.16 and earlier for specific interfaces with the `nv set interface <interface-id> lldp <tlv-type> enabled` command, when upgrading to Cumulus Linux 5.17, the upgrade process converts the interface-specific configuration to a profile configuration using the profile name `auto-migrated-<interface-id>` and the equivalent egress-policy entries.
