ERPS Commands
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 secondary 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)#
ring-port
This command configures a node’s connection to the ring through the east or west interface. Use
the no form to disassociate a node from the ring.
Syntax
ring-port {east | west} interface interface
east - Connects to next ring node to the east.
west - Connects to next ring node to the west.
interface
ethernet unit/port
unit - Unit identifier. (Range: 1)
port - Port number. (Range: 1-12)
Default Setting
Not associated

ERPS Configuration
Command Usage
• Each node must be connected to two neighbors on the ring. For convenience, the ports
connected are referred to as east and west ports. Alternatively, the closest neighbor to the east
should be the next node in the ring in a clockwise direction, and the closest neighbor to the
west should be the next node in the ring in a counter-clockwise direction.
• Note that a ring port cannot be configured as a member of a spanning tree, a dynamic trunk, or
a static trunk.
• If a port channel (static trunk) is specified as a ring port, it can not be destroyed before it is
removed from the domain configuration.
• A static trunk will be treated as a signal fault, if it contains no member ports or all of its
member ports are in signal fault.
• If a static trunk is configured as a ring port prior to assigning any member ports, spanning tree
will be disabled for the first member port assigned to the static trunk.
