Enter the parameters.
Policy Name—Displays the policy to which the class map is being added.
Class Map Name—Select an existing class map to be associated with the policy. Class
maps are created in the Class Mapping page.
Action Type—Select the action regarding the ingress CoS/802.1p and/or DSCP value
of all the matching packets.
-
Use default trust mode—If this options is selected, use the default mode status in
Global Trust mode. If the default mode status is "Not Trusted", ignore the ingress
CoS/802.1p and/or DSCP value and the matching packets are sent as best effort.
-
Always Trust—If this options is selected, the device trusts the matching packet
based on the Global Trust mode (selected in the Global Settings page). It ignores
the Default Mode status (selected in the Global Settings page).
-
Set—If this option is selected, use the value entered in the New Value box to
determine the egress queue of the matching packets as follows:
If the new value (0..7) is a CoS/802.1p priority, use the priority value and the CoS/
802.1p to Queue Table to determine the egress queue of all the matching packets.
If the new value (0..63) is a DSCP, use the new DSCP and the DSCP to Queue Table
to determine the egress queue of the matching IP packets.
Otherwise, use the new value (1..8) as the egress queue number for all the matching
packets.
Traffic Redirect—Select whether to redirect matching traffic. If so, select the unit/port
to which traffic will be redirected.
Redirect Target—Select the unit/port to which traffic will be redirected.
Traffic Mirror—Set to mirror a traffic flow to an analyzer Ethernet port. If this options
is selected the traffic is mirrored to the destination port specified in SPAN Session ID
1. If no target port is specified in SPAN session ID 1 the mirror action will not have
affect. If a policy class map with Traffic Mirror action is applied to an interface – and
that same interface is defined as a source port for SPAN session 1 – all traffic, and not
only specific flow, will be mirrored.
Additional rules and actions of the policy (and ACL) applied to the interface are still
enforced even when Traffic Mirror action is configured. For example:
-
If the ACL action of the mirrored flow is permitted – in addition to being mirrored
– the flow traffic will be also be forwarded. If the action of flow ACL is deny –
