A10E/A28E/A28F Configuration Guide
Enter global configuration mode.
Alpha-
A28E(config)#ethernet ring
ring-id
hello-time
hello-
time
(Optional) configure Hello packets
transmitting time for RRPS.
Alpha-
A28E(config)#ethernet ring
ring-id
restore-delay
delay-time
(Optional) configure fault recovery delay
time for RRPS. The link can be restored to
the original current link until the recovery
delay time timeout.
Alpha-
A28E(config)#ethernet ring
ring-id
priority
priority
(Optional) configure bridge priority for
RRPS.
Alpha-
A28E(config)#ethernet ring
ring-id
description
string
(Optional) configure ring description
information. It should be within 32
characters.
Alpha-
A28E(config)#ethernet ring
ring-id
hold-time
hold-
time
(Optional) configure interface aging time for
RRPS. If RRPS interface has not received
Hello packets in aging time, age this
interface and consider that the link circuit on
link ring has fault. If the node interface is in
Block state, it will enable the blocked
interface temporarily to ensure the normal
communication of all nodes on RRPS.
Alpha-
A28E(config)#ethernet ring
ring-id
protocol-vlan
vlan-id
(Optional) configure RRPS VLAN.
Alpha-
A28E(config)#ethernet ring
upstream-group
group-list
(Optional) configure RRPS uplink interface
group.
The uplink interface group must be
used with failover. It supports dual
homing topology.
The uplink interface group corresponds
to the failover group in one-to-one
relationship.
Master node election: at the beginning, all nodes consider themselves the master
node, one of two interfaces is Block, so no data loop on the ring; when two interfaces
on the ring node receive the same Hello packets for many times, the node considers
that the ring topology is stable and can elect master node. Other nodes will not
enable the blocked interface, usually only one master node, which ensures only one
blocked interface, and ensures the connectivity of the nodes on the ring.
