Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
■ Disable (
disable
): This setting disables LLDP packet transmissions and
reception on a port. In this state, the switch does not use the port for either
learning about LLDP neighbors or informing LLDP neighbors of its pres­
ence.
SNMP Notification. You can enable the switch to send a notification to any
configured SNMP trap receiver(s) when the switch detects a remote LLDP
data change on an LLDP-enabled port (page 12-38).
Per-Port (Outbound) Data Options.
The following table lists the
information the switch can include in the per-port, outbound LLDP packets it
generates. In the default configuration, all outbound LLDP packets include
this information in the TLVs transmitted to neighbor devices. However, you
can configure LLDP advertisements on a per-port basis to omit some of this
information (page 12-40).
