The following applies to QoS policies configured in network mode.
The following types of network QoS policies can be defined: ip-interface and port. By default, when a network QoS policy is created, it is of the ip-interface type.
Create a network QoS policy of the ip-interface type using the configure>qos>network context.
Create a network QoS policy of the port type using the configure>qos>network context.
When a network QoS policy of the ip-interface type is applied to an IP interface configured on network port and hybrid ports, the policy is used for classification of MPLS packets received based on LSP-EXP bits and marking of MPLS-EXP bits for MPLS traffic sent out of the IP interface.
When a network QoS policy of the port type is applied to a network and hybrid port, it is used for classification of IP packets, based on the DSCP or dot1p bits and marking of DSCP or dot1p bits for packets sent out of network or hybrid ports.
On 7210 SAS-R6 and 7210 SAS-R12, an option is available to reallocate resources needed by network QoS ingress to other features sharing the ingress-internal-tcam resource pool. Users must ensure that sufficient resources are available for network ingress QoS, if the user intends to use network ports and network IP interfaces.
