- Auto Advertise—Specifies that the software would automatically 
choose a management address to advertise from all the IP addresses of 
the product. In case of multiple IP addresses the software chooses the 
lowest IP address among the dynamic IP addresses. If there are no 
dynamic addresses, the software chooses the lowest IP address among 
the static IP addresses.
- None—Do not advertise the management IP address.
- 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
