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 RPC to activate, configure, or deactivate the UDLD protocol globally.
• Use the RPC to activate, configure, or deactivate UDLD on specific 100-Gigabit,
10-Gigabit, 40-Gigabit, or Gigabit Ethernet interfaces.
• Use the 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 node, include the node element from the
urn:brocade.com:mgmt:brocade-udld namespace to enable UDLD. The node element
contains elements that allow you to configure the global UDLD parameters. However, the
“presence=true” statement that qualifies the container definition in the
brocade-udld.yang file allows the node element to also function as a leaf element. The
following example enables UDLD globally.
a. Optionally, in the 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 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.
