Description
Protocol Version
The STP protocol version setting. Valid values are STP, RSTP and MSTP.
Forward Delay
The delay used by STP Bridges to transition Root and Designated Ports to
Forwarding (used in STP compatible mode). Valid values are in the range 4
to 30 seconds.
Max Age
The maximum age of the information transmitted by the Bridge when it is
the Root Bridge. Valid values are in the range 6 to 40 seconds, and
MaxAge must be <= (FwdDelay-1)*2.
Maximum Hop Count
This defines the initial value of remainingHops for MSTI information
generated at the boundary of an MSTI region. It defines how many
bridges a root bridge can distribute its BPDU information. Valid values are
in the range 4 to 30 seconds, and MaxAge must be <= (FwdDelay-1)*2.
Transmit Hold Count
The number of BPDU's a bridge port can send per second. When
exceeded, transmission of the next BPDU will be delayed. Valid values are
in the range 1 to 10 BPDU's per second.
