DRA status
This field is used to configure the status of DHCP relay agent
per instance. It can be disabled or configured as client port or
server port. If it is configured as client port then it adds option
82 and /or do learning as per configuration. If it is configured as
server port then it removes option 82 and does learning if we
dont get portid from agent circuit id.
Option82
This specifies the action to be performed on Option 82 on
receiving DHCP discovery packets for this instance. If disabled
DRA will not add Option82 tag to the DHCP packets. If
AddAlways is set then Option 82 is always added. If
AddIfNotExists is set then Option 82 is added only if the
received DHCP packet does not contain Option 82.
Config Sub-Option
This bitmask is used to indicate which all parameters are
configured for this instance. Parameter bit set in this bitmask
will overwrite the automatically derived values of agent circuit
Id and/or port id by the values configured in this MO.
Agent Circuit Id
This is use to configure agent circuit id for this instance. If ACI
bit is set in gsvDRAConfigSubOptionthen this parameter will
overwrite the generated Agent Circuit Id
Remote Agent Id
This is use to configure remote agent id for this instance. This
parameter uniquely identifies the subscriber on the associated
access loop logical port on the Columbia.
SyncRateInfoField
This bitmask is used to indicate what all access loop
characteristic parameters are to be added to access loop
characteristic suboption.
DRA Act For Op82
From Client
This specifies the action to be taken on receiving DHCP
message from the client with option 82. If DHCP message
contains option82 and we want the packet to be dropped then
drop should be set and if we want the packet to be forwarded
then forward should be set.
DRA learning
This field specifies whether DHCP learning is to be done on
this port or not. If enabled DRA will learn the IP Addresses
assigned towards this port using upstream/downstream
packets received on this port.
Port No
This field specifies Atm Port number.Its value is considered
only when the bitmask for portid is set in
