Configuring for Network Management Applications

LLDP (Link-Layer Discovery Protocol)

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 13-48).

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 13-50).
