Commands Reference, Volume 4
qosmod Command
Purpose
Modifies an existing QoS (Quality of Service) Service Category or Policy
Rule.
Syntax
To modify an existing Service Category:
qosmod [ -s ServiceCategory] [ -t OutgoingTOS] [ -b MaxTokenBucket] [ -f FlowServiceType] [ -m MaxRate] service
To modify an exisiting Policy Rule:
qosmod [ -s ServiceCategory] [ -r ServicePolicyRules] [ -l PolicyRulePriority] [ -n ProtocolNumber] [ -A SrcAddrRange] [ -a DestAddrRange] [ -P SrcPortRange] [ -p DestPortRange] policy
Description
The qosmod command modifies the specified Service
Category or Policy Rule entry in the policyd.conf file
and installs the changes in the QoS Manager.
The qosmod command clears out all
the statistics of the old policy. When a qosstat command
is executed immediately after qosmod, the user may not
see all the data connections that were using the older rule shifted to the
modified rule. This is because the reclassification of the data connection
is delayed until a data packet arrives on that connection.
Note
Modifying the priority or filter spec of the rule only results in reclassification
of the data connections which use that particular rule. Connections
using other rules maintain their existing classification.
