Link Layer Discovery Protocol
– 416 –
For information on defining SNMP trap destinations, see “Specifying Trap
Managers” on page 458.
Information about additional changes in LLDP neighbors that occur between
SNMP notifications is not transmitted. Only state changes that exist at the time
of a trap notification are included in the transmission. An SNMP agent should
therefore periodically check the value of lldpStatsRemTableLastChangeTime to
detect any lldpRemTablesChange notification-events missed due to throttling
or transmission loss.
◆ MED Notification – Enables the transmission of SNMP trap notifications about
LLDP-MED changes. (Default: Disabled)
◆ Basic Optional TLVs – Configures basic information included in the TLV field of
advertised messages.
■
Management Address – The management address protocol packet
includes the IPv4 address of the switch. If no management address is
available, the address should be the MAC address for the CPU or for the
port sending this advertisement. (Default: Enabled)
The management address TLV may also include information about the
specific interface associated with this address, and an object identifier
indicating the type of hardware component or protocol entity associated
with this address. The interface number and OID are included to assist
SNMP applications in the performance of network discovery by indicating
enterprise specific or other starting points for the search, such as the
Interface or Entity MIB.
Since there are typically a number of different addresses associated with a
Layer 3 device, an individual LLDP PDU may contain more than one
management address TLV.
Every management address TLV that reports an address that is accessible
on a port and protocol VLAN through the particular port should be
accompanied by a port and protocol VLAN TLV that indicates the VLAN
identifier (VID) associated with the management address reported by this
TLV.
■
Management IPv6 Address – The management address protocol packet
includes the IPv6 address of the switch. If no management address is
available, the address should be the MAC address for the CPU or for the
port sending this advertisement. (Default: Enabled)
Configuring both IPv4 and IPv6 Management Addresses:
a. If both the management-ip-address and the IPv4 address of a VLAN
interface are configured, the primary IPv4 address of the VLAN ID will be
sent in the Management Address TLV of the LLDP PDU transmitted.
