LLDP Configuration

This section describes how to configure LLDP.

The following table lists the LLDP global-level tasks and the default behavior or value for each task.

LLDP Global Configuration Tasks and Default Behaviors or Values

Global Task

Default Behavior or value when LLDP is enabled

Enabling LLDP on a global basis

Default

Specifying the maximum number of LLDP neighbors per device

Automatically set to 2048 neighbors per device

Specifying the maximum number of LLDP neighbors per port

Automatically set to 4 neighbors per port

Enabling SNMP notifications and syslog messages

Disabled

Changing the minimum time between SNMP traps and syslog messages

Automatically set to 2 seconds when SNMP notifications and syslog messages for LLDP are enabled

Enabling and disabling TLV advertisements

When LLDP transmit is enabled, by default the RUCKUS device automatically advertises LLDP capabilities, except for the system description, VLAN name, and power-via-MDI information, which may be configured by the system administrator.

Also, if desired, you can disable the advertisement of individual TLVs.

Changing the minimum time between LLDP transmissions

Automatically set to 2 seconds

Changing the interval between regular LLDP transmissions

Automatically set to 30 seconds

Changing the holdtime multiplier for transmit TTL

Automatically set to 4

Changing the minimum time between port reinitializations

Automatically set to 2 seconds

In this section:

  1. LLDP Configuration Notes and Considerations
  2. Managing LLDP on a Global Basis
    LLDP is enabled by default on individual ports.
  3. Enabling Support for Tagged LLDP packets
    By default, RUCKUS devices do not accept tagged LLDP packets from other vendor devices. To enable support, use the lldp tagged-packets process command in global configuration mode.
  4. Disabling LLDP receive and transmit mode
    To disable the receipt and transmission of LLDP packets on individual ports, enter a command such as the following at the Global CONFIG level of the CLI.
  5. Re-enabling LLDP receive and transmit mode
    After disable the receipt and transmission of LLDP packets on individual ports, it can be re-enabled again.
  6. Enabling LLDP receive only mode
    LLDP receive mode only mode can be configured for individual ports.
  7. Enabling transmit only mode
    LLDP transmit mode only mode can be configured for individual ports.
  8. LLDP port's operating mode change
  9. Configuring the LLDP parameters (Optional)
    The following steps are optional and non-sequential.
  10. LLDP TLVs advertised by the RUCKUS device
