BACP Eligible Group ID of a G.Bond/ETH BCE port. A universally unique 6-octet-long identifier, used by the OPTIONAL BACP, to determine bonding eligibility. When two BCEs have the same g9982BceConfEligibleGroupID on a system, they are eligible to be aggregated on that system. Typically, all BCEs on a BTU-R device would be assigned the same g9982BceConfEligibleGroupID, to assert that all of the BCEs should be in the same bonded group. BCEs with different g9982BceConfEligibleGroupID values MUST NOT be connected to the same GBS. BCEs with the same g9982BceConfEligibleGroupID MAY be connected to different GBS ports. This object MUST be instantiated during BACP initialization, when every BCE belongs to its own GBS. Attempts to change this object MUST be rejected (with the error inconsistentValue), if the BCE is aggregated with other BCEs, i.e., more than one BCE is connected to the same GBS, or if the BCE in question is not eligible to be bonded with other BCEs having the same value (e.g., the bonding is limited to a single line card and BCEs are located on different line cards, or BCEs are the channels of the same line). Note that bonding eligibility is reflected in the ifCapStackTable and its inverse, the ifInvCapStackTable; as such, any modification of g9982BceConfEligibleGroupID MUST be reflected in these tables. A zero-length octet string SHALL be returned on an attempt to read this object on systems not supporting BACP (the value of g9982PortCapBacpSupported for the connected GBS is false). This object maps to the TR-159 attribute aChannelEligibleGroupID.
