Users Manual of XGS-6350-24X4C
By default, Pre-Forward-Time of the transit node is triple longer than Hello-time of the master node so
that it is ensured that the master node can detect the recovery of the ring network before the transit port
enters the pre-forwarding state. If Hello-time configured on the master node is longer than
Fre-Forward-Time of the transit node, loopback is easily generated and broadcast storm is then
triggered.
Users cannot set Edge Hello Time and Edge Fail Time, and their default values are decided by Hello
Time and Fail Time respectively for their values are 1/3 of Hello Time and Fail Time respectively.
The physical interface, the fast-Ethernet interface, the gigabit-Ethernet interface and the aggregation
interface can all be set to be the ring's interfaces. If link aggregation, 802.1X or port security has been
already configured on a physical interface, the physical interface cannot be set to be a ring’s interface
any more.
This protocol is similar with the original EAPS in functions, but its ring’s topology has more expansibility
and flexibility. Hence, MEAPS and EAPS are partially compatible, and the intersection configuration can
be done on the MEAPS ring and the EAPS ring. But a same physical port cannot be simultaneously set
to support MEAPS and EAPS.

27.2.3.1 Configuring the Master Node
Configure a switch to be the master node of a ring network according to the following steps:
Command Purpose
Switch#config
Enters the switch configuration mode.
Switch_config#mether-ring id1
domainid2
Sets a node and enters the node configuration
mode.
id1: instance ID of a node
id2: instance ID of a domain (omitted when it is
0)
Switch_config_ring1#master-node
It is an obligatory step. Configures the node type to
be a master node.
Switch_config_ring1#major-ring[sub-rin
g]
It is an obligatory step. Sets the node’s level to be
one of the major or sub ring node.
Switch_config_ring1#control-vlanvlan-id
It is an obligatory step. Sets the control VLAN and
