EDS-726 Series User’s Manual Featured Functions
3-30
Now Active:
This field will show which communication protocol is being used—Turbo Ring, RSTP, or neither.
Root/Not Root
This field will appear only when selected to operate in RSTP mode. It indicates whether or not this
EDS-726 is the Root of the Spanning Tree (the root is determined automatically).
At the bottom of this page, the user can configure the “Settings” of this function. For RSTP, you
can configure:
Protocol of Redundancy
Setting Description Factory Default
Turbo Ring Select this item to change to the Turbo Ring
configuration page.
None
RSTP (IEEE 802.1W/1D) Select this item to change to the RSTP
configuration page.
None
Bridge priority
Setting Description Factory Default
Numerical value selected
by user
Increase this device’s bridge priority by
selecting a lower number. A device with a
higher bridge priority has a greater chance of
being established as the root of the Spanning
Tree topology.
32768
Forwarding Delay
Setting Description Factory Default
Numerical value input by
user
The amount of time this device waits before
checking to see if it should change to a
different state.
15 (sec.)
Hello time (sec.)
Setting Description Factory Default
Numerical value input by
user
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. Age (sec.)
Setting Description Factory Default
Numerical value input by
user
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.
