discarded. The hostname field is followed by a space, the string “atm”, and
another space. Then, a 1-byte Slot ID field specifies the ingress slot number, and a
1-byte Port No field specifies the ingress port number. Next, the VPI and VCI
denote the virtual circuit that received the DHCP request message from the
subscriber. If the VID is turned on, there is a colon and then the VLAN ID (1 ~
4094). If the VID is turned off, there is neither colon nor VID.
The slot ID, port number, VPI, VCI and MAC are separated from each other by a
forward slash (/) colon (:) or period (.). An example is “SYSNAME atm 3/
10:0.33:12”.
TR-101 uses the same remote ID sub-option format as the Private format.
