D-Link DES-3326SR Layer 3 Switch
Configure the following STP Switch parameters and click the Apply button to implement them:
Parameter Description
Status < Disabled > This field can be toggled between Enabled and Disabled using
the pull-down menu. This will enable or disable the Spanning
Tree Protocol (STP), globally, for the switch.
Max Age: (6 - 40 sec) < 20 > The Max. Age can be set from 6 to 40 seconds. At the end of
the Max. Age, if a BPDU has still not been received from the
Root Bridge, your switch will start sending its own BPDU to all
other switches for permission to become the Root Bridge. If it
turns out that your switch has the lowest Bridge Identifier, it will
become the Root Bridge.
Hello Time: (1 - 10 sec) < 2 > The Hello Time can be set from 1 to 10 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.
Forward Delay: (4 - 30 sec) < 15 >
The Forward Delay can be from 4 to 30 seconds. This is the
time any port on the switch spends in the listening state while
moving from the blocking state to the forwarding state.
Priority: (0 - 61440) < 32768 > A Priority for the switch can be set from 0 to 61440. This
number is used in the voting process between switches on the
network to determine which switch will be the root switch. A
low number indicates a high priority, and a high probability that
this switch will be elected as the root switch.
STP Version < RSTP > Choose RSTP (default) or STP Compatibility. Both versions
use STP parameters in the same way. RSTP is fully
compatible with IEEE 802.1d STP and can function with legacy
equipment.
Tx Hold Count < 3 > This is the maximum number of Hello packets transmitted per
interval. The count can be specified from 1 to 10. The default
value = 3.
Forwarding BPDU < Enabled >
This can enabled or disabled. When it is enabled it allows the
forwarding of STP BPDU packets from other network devices
when STP is disabled on the switch. The default is enabled.
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 (Forward Delay - 1 second)
Max. Age
≥
2 x (Hello Time + 1 second)
