Viewing QoS Settings
When troubleshooting, it is essential to keep track of all your QoS settings that are effective; i.e. that have
been applied. A good way to display all the QoS settings is to use the show configuration snapshot qos
CLI command, which generates a snapshot file of the switch’s QoS current running configuration. See the
following example below:
-> show configuration snapshot qos
! QOS :
qos disable stats interval 30 log level 7 log console
policy condition noip source ip 192.168.10.0 mask 255.255.255.0
policy condition oktftp source ip 192.168.10.0 mask 255.255.255.0 ip protocol 17
destination ip port 69
policy action noip disposition deny
policy action oktftp
policy rule oktftp precedence 200 condition oktftp action oktftp
policy rule noip precedence 100 condition noip action noip
qos apply
Viewing QoS Policy Rules
To display all your pending and applied policy, use the show policy rule CLI command to display infor-
mation about all pending and applied policy rules or a particular policy rule. For example:
-> show policy rule
Policy From Prec Enab Inact Refl Log Save
+BLOCK_20 cli 0 Yes No No No Yes
Cnd/Act: BLOCK_20 -> BLOCK_20
The above display indicates that rule BLOCK_20 is active and is used to classify traffic on the switch (the
Inact field displays No). The rule BLOCK_20 has been configured since the last qos apply command
was entered, as indicated by the plus (+) sign. If the rule has been created recently, it will not be used to
classify traffic until the next qos apply. If the rule has been modified recently, the changes will not be
effective until the next qos apply.
output definitions
+ Indicates that the policy rule has been modified or has been created
since the last qos apply command.
From Where the rule originated.
Prec The precedence of the rule. Precedence determines the order in which
the switch will apply rules.
Enable Whether or not the rule is enabled.
Inactive Whether or not the rule is currently being enforced on the switch.
Reflexive Whether the rule is reflexive or not.
Log Whether the log is activated or not.
Cnd/Act The condition and the action associated with the rule; configured
through the policy condition and policy action commands respectively.
