Chapter 28 Application Patrol

LABEL

DESCRIPTION

 

Inbound

Type how much inbound bandwidth, in kilobits per second, this policy

 

kbps

allows the traffic to use. Inbound refers to the traffic the ZyWALL sends

 

 

to a connection’s initiator.

 

 

If you enter 0 here, this policy does not apply bandwidth management

 

 

for the matching traffic that the ZyWALL sends to the initiator. Traffic

 

 

with bandwidth management disabled (inbound and outbound are both

 

 

set to 0) is automatically treated as the lowest priority (7).

 

 

If the sum of the bandwidths for routes using the same next hop is

 

 

higher than the actual transmission speed, lower priority traffic may not

 

 

be sent if higher priority traffic uses all of the actual bandwidth.

 

 

 

 

Outbound

Type how much outbound bandwidth, in kilobits per second, this policy

 

kbps

allows the traffic to use. Outbound refers to the traffic the ZyWALL sends

 

 

out from a connection’s initiator.

 

 

If you enter 0 here, this policy does not apply bandwidth management

 

 

for the matching traffic that the ZyWALL sends out from the initiator.

 

 

Traffic with bandwidth management disabled (inbound and outbound are

 

 

both set to 0) is automatically treated as the lowest priority (7).

 

 

If the sum of the bandwidths for routes using the same next hop is

 

 

higher than the actual transmission speed, lower priority traffic may not

 

 

be sent if higher priority traffic uses all of the actual bandwidth.

 

 

 

 

Priority

This field displays when the inbound or outbound bandwidth

 

 

management is not set to 0. Enter a number between 1 and 7 to set the

 

 

priority for traffic that matches this policy. The smaller the number, the

 

 

higher the priority.

 

 

Traffic with a higher priority is given bandwidth before traffic with a

 

 

lower priority.

 

 

The ZyWALL uses a fairness-based (round-robin) scheduler to divide

 

 

bandwidth between traffic flows with the same priority.

 

 

The number in this field is ignored if the incoming and outgoing limits

 

 

are both set to 0. In this case the traffic is automatically treated as being

 

 

set to the lowest priority (7) regardless of this field’s configuration.

 

 

 

 

Maximize

This field displays when the inbound or outbound bandwidth

 

Bandwidth

management is not set to 0. Enable maximize bandwidth usage to let

 

Usage

the traffic matching this policy “borrow” any unused bandwidth on the

 

 

 

 

out-going interface.

 

 

After each application or type of traffic gets its configured bandwidth

 

 

rate, the ZyWALL uses the fairness- based scheduler to divide any

 

 

unused bandwidth on the out-going interface amongst applications and

 

 

traffic types that need more bandwidth and have maximize bandwidth

 

 

usage enabled.

 

 

 

 

Log

This field controls what kind of record the ZyWALL creates when traffic

 

 

matches this policy. See Chapter 46 on page 723 for more on logs.

 

 

no - the ZyWALL does not record anything

 

 

log - the ZyWALL creates a record in the log

 

 

log alert - the ZyWALL creates an alert
