Release 14.1.
Specify the Agent Circuit ID suboption (suboption 1) of the DHCP relay agent information
option (option 82) to include in DHCP packets destined for a DHCP server. Optionally
specify that the suboption includes a prefix, textual description, or VLAN tag.
NOTE: For Layer 3 interfaces, when you configure relay-option-82 only, the
Agent Circuit ID is the default. If no VLAN tags are configured, then the default
is the logical interface device (IFL) name. For integrated routing and bridging
(IRB) interfaces, the default is the Layer 2 IFL name and bridge domain name.
The interface to bridge domain relationship may be implicit (the interface is
mapped to the bridge domain by the system based on VLAN tag) or explicit
(the interface is mapped to the bridge domain by configuring it in the bridge
domain definition). For the explicit case, tagging might not be relevant for
the mapping.
