on the Switch.
MSTP
−
Select this parameter to set the Multiple Spanning Tree Protocol (MSTP)
globally on the Switch
TX Hold Count (1-10)
Used to set the maximum number of Hello packets transmitted per interval. The count
can be specified from
1
to
10
. The default is
6.
Forwarding BPDU
This field can be
Enabled
or
Disabled.
When
Enabled,
it allows the forwarding of STP
BPDU packets from other network devices. The default is Enabled.
Loopback Detection
This feature is used to temporarily block STP on the Switch when a BPDU packet has
been looped back to the switch. When the Switch detects its own BPDU packet coming
back, it signifies a loop on the network. STP will automatically be blocked and an alert
will be sent to the administrator. The LBD STP port will restart (change to discarding
state) when the Loopback Detection Recover Time times out. The user may enable or
disable this function using the pull-down menu.
LBD Recover Time
(0:Disable)
This field will set the time the STP port will wait before recovering the STP state set. 0
will denote that the LBD will never time out or restart until the administrator personally
changes it. The user may also set a time between
60
and
1000000
seconds. The default
is
60
seconds.

NOTE:
The Hello Time cannot be longer than the Max. Age. Otherwise, a configuration error will
occur. Observe the following formulas when setting the above parameters:
Max. Age
≤ 2 x (For
ward Delay - 1 second)
Max. Age
≥ 2 x (Hello Time + 1 second)
