G8031 ELPS Commands
This chapter describes the G8031 Ethernet Linear Protection Switching (ELPS) commands.
• backup
• clear
• lockout
• mode
aps-channel level
Use this command to associate CFM with g8031 protection group to carry APS message.
Use the no form of this command to disassociate CFM from g8031 protection group.
Note: It is mandatory for Working-port MEP and Protection-Port MEP to be in different Maintenance Domain but in same Maintenance Level. Moreover, Maintenance Association Vlan-id should be same as g8031 primary-vlan id. If both the conditions are met then, g8031 protection group can be associated to using the 'level' command.
Command Syntax
aps-channel level <0-7>
Parameters
<0-7>
Maintainance Endpoint Level.
Command Mode
G8031 Switching Mode.
Applicability
This command was introduced before OcNOS version 5.0.
Examples
(config)#g8031 eps-instance eps1
(g8031-config-eps-instance)#aps-channel level 7
