This command enables propagation of topology change messages for a secondary ring to the
primary ring. Use the no form to disable this feature.
Syntax
[no] propagate-tc
Default Setting
Disabled
Command Mode
ERPS Configuration
Command Usage
• When a secondary ring detects a topology change, it can pass a message about this event to
the major ring. When the major ring receives this kind of message from a secondary ring, it can
clear the MAC addresses on its ring ports to help the second ay ring restore its connections
more quickly through protection switching.
• When the MAC addresses are cleared, data traffic may flood onto the major ring. The data
traffic will become stable after the MAC addresses are learned again. The major ring will not be
broken, but the bandwidth of data traffic on the major ring may suffer for a short period of time
due to this flooding behavior.
Example
Console(config-erps)#propagate-tc
Console(config-erps)#
