Overview of UDLD and NETCONF

This chapter provides procedures for configuring unidirectional Link Detection (UDLD) using the

NETCONF interface. Refer to the Network OS Administrator’s Guide for information on UDLD and

how it works.

Through the NETCONF interface, you can perform the following operations that affect the

functioning of UDLD:

• Use the <edit-config> RPC to activate, configure, or deactivate the UDLD protocol globally.

• Use the <edit-config> RPC to activate, configure, or deactivate UDLD on specific 100-Gigabit,

10-Gigabit, 40-Gigabit, or Gigabit Ethernet interfaces.

• Use the <get-config> RPC to verify all or part of the global or per-port UDLD configuration.

UDLD must be enabled globally before it can be enabled on a specific interface.

UDLD parameters are defined in the brocade-udld YANG module. For information about the

brocade-udld YANG module, refer to the Network OS YANG Reference Manual.

Configuring UDLD

To enable UDLD globally, perform the following steps.

1. Under the <protocol> node, include the <UDLD> node element from the

urn:brocade.com:mgmt:brocade-udld namespace to enable UDLD. The <UDLD> node element

contains elements that allow you to configure the global UDLD parameters. However, the

“presence=true” statement that qualifies the <udld> container definition in the

brocade-udld.yang file allows the <udld> node element to also function as a leaf element. The

following example enables UDLD globally.

a. Optionally, in the <hello> element, specify for the interface the maximum number of

seconds between successive PDU transmissions. This value overrides the globally

configured value for the interface.

b. Optionally, in the <multiplier> element, specify the UDLD protocol timeout, which is the

product of multiplier and hello interval. If no UDLD PDU is received over a link during

timeout period, the link is deemed unidirectional. Default multiplier value is 5. This value

overrides the globally configured value for the interface.
