Description
Select to enable or disable the STP new root trap option here.
Select to enable or disable the STP topology change trap option here.
Description
Select the STP mode used here. Options to choose from are MSTP,
RSTP, and STP.
Description
Select the STP priority value here. This value is between 0 and 61440.
By default, this value is 32768. The lower the value, the higher the
priority.
Description
Enter the bridge's maximum age value here. This value must be
between 6 and 40 seconds. By default, this value is 20 seconds. The
maximum age value may be set to ensure that old information does
not endlessly circulate through redundant paths in the network,
preventing the effective propagation of the new information. Set by the
Root Bridge, this value will aid in determining that the switch has
spanning tree configuration values consistent with other devices on the
bridged LAN.
After selecting RSTP/STP as the Spanning Tree Mode, this
parameter will be available. Enter the bridge's hello time value here.
This value must be between 1 and 2 seconds. By default, this value is
2 seconds. This is the interval between two transmissions of BPDU
packets sent by the Root Bridge to tell all other switches that it is
indeed the Root Bridge. This field will only appear here when STP or
RSTP is selected for the STP Version. For MSTP, the Hello Time must
be set on a port per port basis.
Enter the bridge's forwarding time value here. This value must be
between 4 and 30 seconds. By default, this value is 15 seconds. Any
port on the switch spends this time in the listening state while moving
from the blocking state to the forwarding state.
Enter the transmit hold count value here. This value must be between
1 and 10 times. By default, this value is 6 times. This value is used to
set the maximum number of Hello packets transmitted per interval.
Enter the maximum number of hops that are allowed. This value must
be between 1 and 40 hops. By default, this value is 20 hops. This
value is used to set the number of hops between devices in a spanning
