Ring Port
In Rapid Super Ring environment, you should have 2 Ring Ports. No matter this switch is
Ring Master or not, when configuring RSR, 2 ports should be selected to be Ring Ports.
After Ring Master is selected,
one Ring Port will become the forwarding port and the other
will become the blocking port.
Version
There are 2 versions provided in JetNet 5008G-P managed switch.
Version 1:
Version 1 is Legacy Super Ring Client mode for users to backward compatible
with JetNet 4000/4500 series switches. JetNet 5008G-P supports
Client
mode only. After
connected Ring Ports to JetNet 4000/4500 Super Ring switches, the 2 Ring Ports can pass
through the hello packets sent from the ring master of the Super Ring. Thus the ring
master of the Super Ring can detect the link status well.
Version 2:
Version 2 is Rapid Super Ring mode. Version 2 is the default setting when you
selected the checkbox of Rapid Super Ring.
Dual Homing II
Dual Homing II is the important feature
of Korenix 2
nd
generation Ring
redundancy technology. When you
want to connect multiple RSR or form
redundant topology with other vendors,
Dual Homing II allows you to enable
RSTP and RSR from one device at the
same. Thus you have more flexibility
and standard (RSTP) way to construct
your network topology.
As what is shown in the figure, you can
enable RSTP and RSR from JetNet
5008G-P at the same. Then JetNet
5008G-P ring can be protected by Rapid Super Ring while the connection to the other
vendors can be protected by RSTP.
In Dual Homing I released with JetNet 4000/4500 series, you have to configure additional
port as Dual Homing port to 2 uplink switches. In Dual Homing II, you don’t need to
configure specific port to connect to other protocol. Just keep RSTP in Enable, Dual
Homing II will then make connection and be protected by standard RSTP.
Note: Due to RSTP mechanism restriction, the path/paths between the 2 Dual Homing
devices should not be the blocking path. This is a known restriction in firmware V1.2.
