Description
7
Alpha-A28E(config)#ethernet
ring-protection ring-id
holdoff-time holdoff-time
(Optional) system delays fault report
time when current link faults after
configuring ring HOLDOFF timer. It can
avoid current link switching frequently.
50ms switching performance will be
affected by HOLDOFF timer value if
it is too bigger, so it is 0 by default.
8
Alpha-A28E(config)#ethernet
ring-protection trap enable
(Optional) enable ERPS fault information
report to NMS.
7.6.5 (Optional) creating ERPS sub-ring

Only the intersecting rings network contains master ring and sub-ring.

The master ring configuration is identical to the configuration of single ring or
tangent ring. For details, see section 7.6.4 Creating ERPS ring.

Un-crossed node on sub-ring is identical to configuration of single ring or tangent
ring; see section 7.6.4 Creating ERPS ring for details.
Configure ERPS intersecting rings for A10E/A28E as below.
Step
Configuration
Description
1
Alpha-A28E#config
Enter global configuration mode.
2
Alpha-
A28E(config)#ethernet
ring-protection ring-id
east { port port-id |
port-channel port-
channel-number } west
{ port port-id | port-
channel port-channel-
number } [ node-type rpl-
owner rpl { east |
west } ] [ not-
revertive ] [ protocol-
vlan vlan-id ] [ block-
vlanlist vlan-list ]
Create sub-ring and configure node as
RPLOwner on crossover node.
Protection ring changes to non-revertive mode
if configured parameter of not-revertive. Flow
switches back to current link from protection
link after current link fault restore but it does
not switch if in non-revertive mode.
The link between two crossover nodes in
intersecting rings belongs to master ring,
so either east-bound or wester-bound
interface can be configured for sub-ring.
