Application Traffic Prioritization
1
Syntax: [no] server attack-interval classify interval-1 de-classify interval-2
The interval-1 variable classifies traffic as attack traffic when the connection rate against a VIP
exceeds the maximum rate for the time interval specified in multiples of 100 milliseconds.
The interval-2 variable declassifies traffic as attack traffic when the connection rate against a
VIP remains below the maximum rate for the time interval specified in multiples of
100 milliseconds.
Displaying number of packets dropped
Use the show axp vip-drop-count command to display the number of packets dropped due to the
application traffic prioritization feature. For example, enter the following command.
Virtual ADX# show axp drop
############ BP 1/1 output start ############

Displaying traffic priority
Use the show server virtual command to display the traffic priority value currently in use by the VIP,
and the current VIP TCP and UDP connection rates.
