Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
system_cap
For outbound advertisements, this TLV includes a
bitmask of supported system capabilities (device
functions). Also includes information on whether the
capabilities are enabled.
(Default: Enabled)
For example, if you wanted to exclude the system name TLV from the
outbound LLDP advertisements for all ports on a switch, you would use this
command:
ProCurve(config)# no lldp config 1-24 basicTlvEnable
system_name
If you later decided to reinstate the system name TLV on ports 1-5, you would
use this command:
ProCurve(config)# lldp config 1-5 basicTlvEnable
system_name
Configuring Support for Port Speed and Duplex
Advertisements
This feature is optional for LLDP operation, but is required for LLDP-MED
operation.
Port speed and duplex advertisements are supported on the switches covered
in this guide to inform an LLDP endpoint and the switch port of each other’s
port speed and duplex configuration and capabilities. Configuration
mismatches between a switch port and an LLDP endpoint can result in
excessive collisions and voice quality degradation. LLDP enables discovery of
such mismatches by supporting SNMP access to the switch MIB for comparing
the current switch port and endpoint settings. (Changing a current device
configuration to eliminate a mismatch requires intervention by the system
operator.)
