Overview

A command has been written to suppress the IPv4 / IPv6 management address transmission in outgoing LLDP packets.

A local LAN device transmits organization-specific information in the form of type, length, and value (TLV). The organization-associated values are stored in the LLDP organizationally defined local device LLDP MIB extensions. Management address TLV in IPv4 and IPv6 environments is optional from the TLV basic management set.

TLV basic management set

  • Port description TLV — Describes the port in an alpha-numeric format. The value equals the ifDescr object, if the LAN device supports RFC 2863.

  • System name TLV — Assigns the system name in an alpha-numeric format. The value equals the sysName object, if the LAN device supports RFC 3418.

  • System description TLV — Describes the network entity in an alpha-numeric format. The system description TLV includes the system name, versions of hardware, operating system, and networking software supported in the device. The value equals the sysDescr object, if the LAN device supports RFC 3418.

  • System capabilities TLV — Indicates primary functions of the device and if they are enabled in the device.

  • Management address TLV — Indicates the addresses of the local LLDP agent. Other remote managers can use this address to obtain information related to the local device.

The command lldp config <all> ipAddrEnable <IP_ADDR> is used to advertise specific IP address through the port.

The command no lldp config <PORT NO> basicTlvEnable management_addr suppresses the IP address to be advertised.
