DES-7200 Configuration Guide Chapter 5 RERP Configuration
5-26
rerp oper hello interval : 1
rerp oper fail interval : 3
ring master : 00d0.f822.35ad
ctrl-vlan : 4091
edge-vlan : 4092
role : master
primary-port : GigabitEthernet 0/1(down)
secondary-port : GigabitEthernet 0/2(forwarding)
Step 3: Restore the link between SwitchA and SwitchC and disconnect the link
between SwitchB and SwitchC (simulating that the public link is failed), and then verify
the RERP configurations on Master device.
1) Verify the RERP configurations on the Master device of primary ring; key point: state
of primary and secondary ports of SwitchA (Master of primary ring).
SwitchA#show rerp
rerp state : enable
rerp admin hello interval: 1(*1s)
rerp admin fail interval : 3(*1s)
rerp local bridge : 00d0.f822.35ad
-----------------------------------
region 1
ring : 1
rerp oper hello interval : 1
rerp oper fail interval : 3
ring master : 00d0.f822.35ad
ctrl-vlan : 4091
edge-vlan : 4092
role : master
primary-port : GigabitEthernet 0/1(forwarding)
secondary-port : GigabitEthernet 0/2(forwarding)
From the above information, we can learn that the primary ring is failed, and the master
device unblocks its secondary port which was blocked originally.
2) Verify the RERP configurations on the Master device of subring; key point: state of
primary and secondary ports of SwitchD (Master of subring).
SwitchD#show rerp
rerp state : enable
rerp admin hello interval: 1(*1s)
rerp admin fail interval : 6(*1s)
rerp local bridge : 00d0.f822.3416
