Rationale for revision
The Link Aggregation TLV was added to the dot1 LLDP TLVs (moved from dot3) in
802.1AB-2009 and tables were added to Local and Remote System Information to
support it. All TLVs are supposed to have an enable in the Configuration
Group but this was not added for the Link Aggregation TLV.
Also, there is an error in table D-5 for lldpV2Xdot1ConfigPortVlanTable. The LLDP reference says that it augments itself and that lldpV2Xdot1ConfigCnTable augments lldpV2dot1LocManVidEntry. The MIB says that the entries for both augment lldpB2PortConfigEntry.
The objects added to the Congestion Notification were not added to the
security considerations in D.4.4.
Proposed text
D4.2
In Table D-5, add the following to the Configuration Group:
lldpV2Xdot1ConfigLinkAggTable Augments lldpV2Xdot1LocLinkAggEntry
lldpV2Xdot1ConfigLinkAggTxEnable Normal LLPDUs, 9.1.2.1 of IEEE Std 802.1AB
For the entries in Table D-5 for lldpV2Xdot1ConfigPortVlanTable and for
lldpV2Xdot1ConfigCnTable, change the LLDP reference column to “Augments
lldpB2PortConfigEntry”
D4.4
Add to the list of objects following f) and adjust the later lettered bullets
accordingly:
lldpV2Xdot1ConfigLinkAggTxEnable
lldpXdot1CnConfigCnTxEnable
Add to the numbered list under g):
lldpV2Xdot1LocCNPVIndicators
lldpV2Xdot1LocReadyIndicators
Add to the numbered list under h):
lldpV2Xdot1ConfigLinkAggTable
Augments lldpV2Xdot1LocLinkAggEntry
lldpV2Xdot1ConfigLinkAggTxEnable
Normal LLPDUs, 9.1.2.1 of IEEE Std 802.1AB
lldpV2Xdot1RemCNPVIndicators
lldpV2Xdot1RemReadyIndicators
D4.5
Add to the MIB in the section on Configuration for the basic TLV set:
lldpV2Xdot1ConfigLinkAggTable : configure the transmission of the
-- Link Aggregation TLVs on set of ports.

lldpV2Xdot1ConfigLinkAggTable OBJECT-TYPE
SYNTAX SEQUENCE OF LldpV2Xdot1ConfigLinkAggEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"A table that controls selection of LLDP Link Aggregation TLVs
to be transmitted on individual ports."
::= { lldpV2Xdot1Config 1 }
lldpV2Xdot1ConfigLinkAggEntry OBJECT-TYPE
SYNTAX LldpV2Xdot1ConfigLinkAggEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"LLDP configuration information that controls the
transmission of IEEE 802.1 organizationally defined
Link Aggregation TLV on LLDP transmission capable ports.
This configuration object augments the lldpV2PortConfigEntry of
the LLDP-MIB, therefore it is only present along with the port
configuration defined by the associated lldpV2PortConfigEntry
entry.
Each active lldpConfigEntry is restored from non-volatile
storage (along with the corresponding lldpV2PortConfigEntry)
after a re-initialization of the management system."
AUGMENTS { lldpV2PortConfigEntry }
::= { lldpV2Xdot1ConfigLinkAggTable 1 }
LldpV2Xdot1ConfigLinkAggEntry ::= SEQUENCE {
lldpV2Xdot1ConfigLinkAggTxEnable TruthValue
}
lldpV2Xdot1ConfigLinkAggTxEnable OBJECT-TYPE
SYNTAX TruthValue
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"The lldpV2Xdot1ConfigLinkAggTxEnable, which is defined
as a truth value and configured by the network management,
determines whether the IEEE 802.1 organizationally defined
Link Aggreagation TLV transmission is allowed on a given LLDP
transmission capable port.
The value of this object is restored from non-volatile
storage after a re-initialization of the management system."
REFERENCE
"9.1.2.1 of IEEE Std 802.1AB"
DEFVAL { false }
::= { lldpV2Xdot1ConfigLinkAggEntry 1 }
Impact on existing networks
This change shouldn’t affect the operation of existing networks. Some are
probably still using the 802.3 Link Aggregation TLV from 802.1AB-2005. Those
that use the 802.1 Link Aggregation TLV from 802.1AB-2009 and 802.1Q-2011
presumably have implementation dependent means for enabling and disabling it
or the always or never send it.
