instances in the Switch Stack.
Label 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 remaining Hops 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.
