Bridge Priority: Allows you to set the Bridge Priority. Priority values are Descending (i.e. 100 has a higher priority than
1000). The Bridge Priority plus the MSTI Instance concatenated with the 6-byte MAC Address of the Switch forms the
Bridge Identifier. In MSTP this is the priority of the CIST. We do not recommend changing this value without consulting
a knowledgeable Network Administrator.
Forward Delay: Allows you to set the delay used when Transmitting Root and Designated Ports BPDU. The valid
range is 4-30 seconds with a default of 15 seconds. We do not recommend changing this value without consulting a
knowledgeable Network Administrator.
Max Age: Allows you to set the Maximum Age of the BPDU Transmitted by the Root Bridge. The valid Range is 6-40
seconds with the default of 20 seconds (MaxAge must be <= (FwdDelay-1)*2). We do not recommend changing this value
without consulting a knowledgeable Network Administrator.
Maximum Hop Count: Allows you to set the number of Remaining Hops for STP BPDUs generated at the boundary
of an MSTP region. The valid range is 6-40 hops. We do not recommend changing this value without consulting a
knowledgeable Network Administrator.
Transmit Hold Count: Allows you to set the number of BPDUs a Bridge Port can send per second. When per second
limit is exceeded the transmission of the next BPDU will be delayed. The valid Range is 1-10 BPDUs per second. We do
not recommend changing this value without consulting a knowledgeable Network Administrator.
Advanced Settings
Edge Port BPDU Filtering: Allows you to set whether a Port explicitly configured as an Edge Port will Transmit and
receive BPDUs.
Edge Port BPDU Guard: Allows you to set whether a Port explicitly configured as an Edge Port will Disable itself
upon reception of a BPDU. If Enabled he Port will enter the Error-Disabled State and will be removed from the
active topology.
Port Error Recovery: Allows you to set whether a Port in the Error-Disabled State can automatically re-enabled itself. If
Recovery is not enabled Ports have to be Disabled then Re-enabled for normal STP operation to resume. The condition
is also cleared by a system Reboot.
Port Error Recovery Timeout: Allows you to set the Port Error Recovery Timeout. The valid Range is 30-86400 seconds.
