IP filter and IP filter group configurations

You can create an IP filter, which enables the switch to classify traffic. In turn, you

can create an access control list from a series of defined filters to create an IP filter

group. The filter group then determines access to and denial of network services.

Drop Precedence Loss Sensitive

Not Loss Sensitive

Choose the drop value precedence to use for traffic with the associated

802.1p user priority value with the identified queue. Selecting a Loss

Sensitive value specifies a low packet drop precedence; selecting a Not

Loss Sensitive value specifies a high packet drop precedence.

Note: Generally, low packet drop precedence receives preferential

treatment.

Note: Mappings created on the DSCP mapping modification page are used at egress

for marking traffic:

• Trusted and unrestricted IP traffic—If you select the re-marking action of using the egress map,

the mappings determine the 802.1p priority and drop precedence values associated with

packets based on the DSCP of the received packet.

• Untrusted and untresticted traffic—If you select the re-marking action of using default, the

mappings determine the 802.1p priority and drop precedence values associated with packets

based on the DSCP value you specified in the Update DSCP action field.

untrusted, and unrestricted ports—refer to
