Command Usage
This option advertises network policy configuration information, aiding in the
discovery and diagnosis of VLAN configuration mismatches on a port. Improper
network policy configurations frequently result in voice quality degradation or
complete service disruption.
Example
Console(config)#interface ethernet 1/1
Console(config-if)#lldp med-tlv network-policy
Console(config-if)#
lldp notification

Command Usage
â—†
This option sends out SNMP trap notifications to designated target stations at
the interval specified by the lldp notification-interval
command. Trap
notifications include information about state changes in the LLDP MIB (IEEE
802.1AB), or organization-specific LLDP-EXT-DOT1 and LLDP-EXT-DOT3 MIBs.
â—†
SNMP trap destinations are defined using the snmp-server host
command.
â—†
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.
Example
Console(config)#interface ethernet 1/1
Console(config-if)#lldp notification
Console(config-if)#
