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 to. Valid values
are in the range 6 to 40 hop
s.
Transmit Hold Count
The number of BPDUs 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 BPDUs per second.
Advanced Settings
Setting Description
Edge Port BPDU
Filtering
Control whether a port explicitly configured as Edge will transmit and
receive BPDUs.
Edge Port BPDU
Guard
Control whether a port explicitly configured as Edge will disable itself
upon reception of a BPDU. The port will enter the error-disabled state
and
will be removed from the active topology.
Port Error Recovery
Control whether a port in the error-disabled state automatically will be
enabled after a certain time. If recovery is not enabled, ports have to be
disabled and re-enabled for normal STP operation. The condition is also
cleared by a system reboot.
Port Error Recovery
Timeout
The time to pass before a port in the error-disabled state can be
enabled. Valid values are between 30 and 86400 seconds (24 hours).
