Configuring the default MAC ID
You can configure the MAC ID. The device appends this ID number to the end of the permanent
portion of the ERP MAC address (00-00-00-00-00- <01 or ERP ID>) in R-APS messages. By default
00-00-00-00-00-01 is used as the dst MAC, which is always used by Version 1 of ITU-T 8032. If
Version 2 is configured, then the raps-default-mac command can be negated by entering the no
raps-default-mac command. The configured ERP ID will appear as the last 8-bit number in the
destination MAC.
For more information about feature support for version 1 and 2, see “Setting the ITU-T G.8032
version number” .
Syntax: [no] raps-default-mac
Configuring R-APS MEL value
The R-APS Maintenance Entity Group Level (MEL) value can be configured. The R-APS MEL value is
carried in ERP PDUs. The default R-APS MEL value is 7.
Syntax: [no] raps-mel mel value
Configuring R-APS topology change propagation
When there is a topology change in a sub-ring, the information needs to be propagated over the
major ring. This propagation involves transmission of RAPS (MAC flush event) PDUs over the major
ring associated with the sub-ring. This results in a filter database (FDB) flush on the major ring
nodes.
Syntax: [no] raps-propagate-tc
Enabling the ERP configuration
You must apply the enable command to activate an ERP configuration. You can use the no
command to disable the configuration.
Within an interconnected ring topology, in the major ring, you must first configure two interfaces. In
a sub-ring, at least one interface must first be configured before enabling the ERP instance.
Syntax: [no] enable
Example of a non-RPL node configuration in a major ring:
(config)# erp 1
(config-erp-1)#right-interface vlan 2 e 1/2
(config-erp-1)#left-interface vlan 2 e 1/1
(config-erp-1)#enable
Configuring interfaces
Each ERN in a major ring must have explicitly defined left and right interfaces so that ERP can
function properly. ERNs in a sub-ring must have at least one interface defined so that ERP can
function properly.
