Used to provision the format of the remote ID string. This string is returned by the DHCPv4 relay agent in option 82 or DHCPv6 relay agent in option 37 or in PPPoE Vendor Specific tag. TR-101 states that the format of the remote ID should be user defineable. The string may contain both fixed static string elements specified by the user and also variable and fixed length elements which are populated by the network element. Variable length elements are specified by enclosing the names of the variables with a dollar sign '$'. For instance, a user could specify a circuit id string as follows: 'TA1148-$accessnodeid$ Port: $port$ $vpi$/$vci$' which would expand to 'TA1148-TID Port: 1 0/35'. In this implementation, the access-node-id is equivalent to the system's provisioned TID or SNMP sysName and map is equivalent to the ethernet flow name . If this string is provisioned zero-length, then the default format is used. The total length of the expanded string MUST NOT exceed 63 characters. Variables include (but are not limited to) the following: Variable Name Character Length accessnodeid Varies chassis-id Varies shelf 2 slot 3 port 3 vpi 4 vci 5 q-vid 4 pbits 1 map varies If a user defined remote ID is not desired, this object can be set to simply 'default'.
