vRtrIfDHCPRelayCircuitId 1.3.6.1.4.1.6527.3.1.2.3.19.1.3

The value of the object vRtrIfDHCPRelayCircuitId specifies whether or not the circuit-id suboption is present, and if it is present what information goes in it. If the value of this object is set to 'none', the circuit-id suboption will not be part of the information option (option 82). If the value of this object is set to 'ifIndex', the value of the interface index is used. If the value of this object is set to 'asciiTuple', the ASCII-encoded concatenated tuple consisting of the - access-node-identifier - service-id - interface-name - SAP-id (only if the value of vRtrIfType is 'serviceIesGroup') is used. If the value of this object is set to 'sapId', the ASCII-encoded SAP-id is used. If the value of this object is set to 'vlan-ascii-tuple' - the format will include VLAN-id and dot1p bits in addition to what is included in ascii-tuple already. The format is supported on dot1q and qinq encapsulated ports only. Thus, when the option 82 bits are stripped, dot1p bits will be copied to the Ethernet header of an outgoing packet. -- -- The value 'sapId(3)' can only be used if the interface is a service -- interface. -- The values 'portId(5)' and 'ifName(6)' can only be used if the -- interface is a network interface.
