dynamic addresses, the software chooses the lowest IP address among
the static IP addresses.

- Manual Advertise—Select this option and the management IP address to
be advertised. We recommend you select this option when the device is
in Layer 3 system mode and the device is configured with multiple IP
addresses (this is always true on SG500X/ESW2-550X devices).
• 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 written to the
Running Configuration file.
LLDP MED Network Policy
LLDP Media Endpoint Discovery (LLDP-MED) is an extension of LLDP that provides
the following additional capabilities to support media endpoint devices. Some of
the features of the LLDP Med Network Policy are:
• Enables the advertisement and discovery of network polices for real-time
applications such as voice and/or video.
• 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.
• Troubleshooting information. LLDP MED sends alerts to network managers
upon:
- Port speed and duplex mode conflicts
- QoS policy misconfigurations
