DESCRIPTION

Inbound kbps

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

kbps

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

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

Enable maximize bandwidth usage to let the traffic matching this policy “borrow”

Bandwidth

any unused bandwidth on the out-going interface.

Usage

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. Please see Chapter 45 on page 715 for more information.

 

no - the ZyWALL does not record anything

 

log - the ZyWALL creates a record in the log

 

log alert - the ZyWALL creates an alert
