Configuring Discovery LLDP and CDP 8 By default, Bonjour is enabled on all interfaces that are members of the Management VLAN. To globally enable Bonjour: STEP 1 Click Administration > Discovery - Bonjour. The Discovery - Bonjour page opens. STEP 2 Select Enable to enable Bonjour Discovery globally on the switch. STEP 3 Click Apply. Bonjour is enabled or disabled on the switch according to the selection. LLDP and CDP LLDP (Link Layer Discovery Protocol) and CDP (Cisco Discovery Protocol) are link layer protocols for directly-connected LLDP and CDP-capable neighbors to advertise themselves and their capabilities to each other. By default, the switch sends an LLDP/CDP advertisement periodically to all its interfaces and terminates and processes incoming LLDP and CDP packets as required by the protocols. In LLDP and CDP, advertisements are encoded as TLV (Type, Length, Value) in the packet. The following CDP/LLDP configuration notes apply: • CDP/LLDP can be globally enabled or disabled and enabled/disabled per port. The CDP/LLDP capability of a port is relevant only if CDP/LLDP is globally enabled. • If CDP/LLDP is globally enabled, the switch filters out incoming CDP/LLDP packets from ports that are CDP/LLDP-disabled. • If CDP/LLDP is globally disabled, the switch can be configured to discard, VLAN-aware flooding, or VLAN-unaware flooding of all incoming CDP/LLDP packets. VLAN-aware flooding floods an incoming CDP/LLDP packet to the VLAN where the packet is received excluding the ingress port. VLANunaware flooding floods an incoming CDP/LLDP packet to all the ports excluding the ingress port. The default is to discard CDP/LLDP packets when CDP/LLDP is globally disabled. You can configure the discard/ flooding of incoming CDP and LLDP packets from the CDP Properties page and the LLDP Properties page respectively.
