Parameter
Default
Value
Description
TrapThresholdMinCount 10 Minimum number of traps required to reach the
the TrapThreshold rate. For example, if Trap-
Threshold is set to 10 traps per minute and Trap-
ThresholdMinCount is set to 5, the port will be
disabled after 5 traps are received at the rate of
10 traps per minute (for example: 5 traps in 30
seconds). This parameter value must be greater
than 2, and the default parameter value is 10.
This parameter is ignored if TrapThreshold is set
to 0. Larger values increase the accuracy of
detecting the trap rate, but also increase the time
between a trap surge and the SM disabling a
port. Very small values can result in a port being
disabled after a few traps.
Suppress1x 0 When Suppress1x is enabled, the SM will not
activate 1x links and will take down any active 1x
links found
McDosThreshold 0 Multicast Denial of Service Threshold (McDos)
A pathological node can cause a denial of service
attack by excessive creates and deletes of
multicast groups. The following limits the number
of multicast Set/Delete sequences that a
node can issue before the SM takes action to
quiet the node.
The number of deletes allowed within a given
interval is limited by the following parameters.
When McDosThreshold is zero, monitoring of
MC DOS is disabled.
McDosInterval 60 McDos Interval
The interval in seconds for the number of deletes
allowed.
Default is 60.
McDosAction 0 McDos Action
The action to take if McDos is suspected.
0 = Port will be disabled.
1 = Port will be bounced.
