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 are additional points about CDP/LLDP configuration:
• 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.
