The following fields relate to the Management Address:
• Advertisement Mode—Select one of the following ways to advertise the IP
management address of the switch:
- Auto Advertise—Send the current management IP address of the switch,
regardless of whether it was acquired via DHCP or manually.
- None—Do not advertise the management IP address.
- Manual Advertise—Select this option and the management IP address to
be advertised. We recommended that this option be selected when the
switch is in Layer 3 mode and the switch is configured with multiple IP
addresses.
• IP Address—If Manual Advertise was selected, select the Management IP
address from the addresses provided.
STEP 3 Enter the relevant information, and click Apply. The port settings are modified, and
the switch is updated.
LLDP MED Protocol
LLDP Media Endpoint Discovery
(LLDP-MED) is an enhancement of LLDP that
provides additional capabilities to support media devices.
LLDP-MED:
• Provides detailed network topology information, including the devices
located on the network and their location, for example, which IP phone is
connected to which port, which software is running on which switch, and
which port is connected to which PC.
• Device location discovery to allow creation of location databases and, in the
case of Voice over Internet Protocol (VoIP), Emergency Call Service (E-911)
by using IP Phone location information.
