Communication Redundancy STP/RSTP/MSTP
4-9
Redundancy Protocol
Setting Description Factory Default
RSTP (IEEE 802.1W/1D) Select the RSTP configuration page. None
Turbo Ring Select the Turbo Ring configuration page. None
Turbo Ring V2 – –
Turbo Chain – –
MSTP (IEEE 802.1s) Select the MSTP configuration page. None
Forwarding Delay (sec.)
Setting Description Factory Default
Numerical value input by user
(4-30)
The amount of time this device waits before checking
to see if it should change to a different state.
15
Hello time (sec.)
Setting Description Factory Default
Numerical value input by user
(1-10)
The root of the Spanning Tree topology periodically
sends out a “hello” message to other devices on the
network to check if the topology is healthy. The “hello
time” is the amount of time the root waits between
sending hello messages.
2
Max Hops
Setting Description Factory Default
Numerical value input by user
(6-40)
The MSTP maximum hops value is the maximum
number of hops in the region. Configure the maximum
number of hops a BPDU can be forwarded in the MSTP
region.
20
Max. Age (sec.)
Setting Description Factory Default
Numerical value input by user
(6-40)
If this device is not the root, and it has not received a
hello message from the root in an amount of time
equal to “Max. Age,” then this device will reconfigure
itself as a root. Once two or more devices on the
network are recognized as a root, the devices will
renegotiate to set up a new Spanning Tree topology.
20
Revision Level
Setting Description Factory Default
Numerical value input by user
(0-65535)
The MSTP revision level is the revision number of the
configuration. All EDS switches in an MSTP region
must be configured with the same revision level.
0
Region Name
Setting Description Factory Default
Character string The region name helps define the logical boundary of
the network. All EDS switches in an MSTP region must
be configured with the same name.
MSTP
Config Confirm
Setting Description Factory Default
Enable/Disable Clicking “Activate” button will only save the MSTP
settings temporarily; you can select to enable this
configuration to activate the MSTP settings during the
operation.
