- 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
- QoS policy misconfigurations
