Network QoS Policies
Quality of Service Guide 105
Context config>qos>network
Description This command is used to enter the CLI node that creates or edits policy entries that specify the DiffServ
code points to forwarding class mapping for all IP packets and define the MPLS EXP bits to
forwarding class mapping for all labeled packets.
When premarked IP or MPLS packets ingress on a network port, they get a Per Hop Behavior (that is,
the QoS treatment through the router-based on the mapping defined under the current node.
default-action
Syntax default-action fc fc-name profile {in | out}
Context config>qos>network>ingress
Description This command defines or edits the default action to be taken for packets that have an undefined DSCP
or MPLS EXP bits set. The default-action command specifies the forwarding class to which such
packets are assigned.
Multiple default-action commands will overwrite each previous default-action command.
Default default-action fc be profile out
Parameters fc fc-name — Specify the forwarding class name. All packets with DSCP value or MPLS EXP or
dot1p bits bits that is not defined will be placed in this forwarding class.
Default None, the fc name must be specified
Values be, l2, af, l1, h2, ef, h1, nc
profile {in | out} — All packets that are assigned to this forwarding class will be considered in or
out of profile based on this command. In case of congestion, the in-profile packets are
preferentially queued over the out-of-profile packets.
Default None
Values in, out
ip-criteria
Syntax [no] ip-criteria
Context config>qos>network>ingress
Description IP criteria-based network ingress policies are used to select the appropriate ingress queue and
corresponding forwarding class for matched traffic. This command is used to enter the context to create
or edit policy entries that specify IP criteria such as IP quintuple lookup or DiffServ code point.
The 7750 SR OS implementation will exit on the first match found and execute the actions in
accordance with the accompanying action command. For this reason, entries must be sequenced
correctly from most to least explicit.
