Command Usage
â—†
The ring node identifier is used to identify a node in R-APS messages for both
automatic and manual switching recovery operations.
For example, a node that has one ring port in SF condition and detects that the
condition has been cleared, will continuously transmit R-APS (NR) messages
with its own Node ID as priority information over both ring ports, informing its
neighbors that no request is present at this node. When another recovered
node holding the link blocked receives this message, it compares the Node ID
information with its own. If the received R-APS (NR) message has a higher
priority, this unblocks its ring ports. Otherwise, the block remains unchanged.
â—†
The node identifier may also be used for debugging, such as to distinguish
messages when a node is connected to more than one ring.
Example
Console(config-erps)#node-id 00-12-CF-61-24-2D
Console(config-erps)#
non-erps-dev-protect
