Summary of major functions of QoS policies

The following tables list a summary of the major functions performed by QoS policies.

Table: QoS policy types and descriptions for 7210 SAS-K 2F1C2T
Policy type	Applied at…	Description
Service ingress	Access SAP-ingress	option to define up to eight FC queues and queue parameters to define queue characteristics (For example, scheduler priority and weight, rates, and so on) option to defines up to 16 FC meters and meter parameters to define meter characteristics (For example, rates, CBS, MBS, and so on) for traffic classification, defines match criteria to map flows to the queues based on dot1p or IP DSCP criteria or MAC criteria or IP criteria
Service egress	Access SAP-egress	allocates up to eight FC queues and maps FCs to the queues. defines FC-to-remarking values, through the use of remark policies defines queue parameters to define queue characteristics (For example, scheduler priority and weight, rates, and so on)
Egress rate	Access port and Access-uplink port	configures the maximum bandwidth available for traffic sent out of a specified port
Network QoS	Access-uplink port	at ingress, defines up to eight FC queues and queue parameters to define queue characteristics (For example, scheduler priority and weight, rates, and so on) for traffic classification, defines match criteria to map flows to the queues based on dot1p and DSCP values at egress, defines FC to remarking values, through the use of remark policies
Network queue	Access-uplink port	allocates up to eight FC queues and maps FCs to the queues. defines queue parameters to define queue characteristics (For example, scheduler priority and weight, rates, and so on)
Slope policies	SAP queues (both ingress and egress) and Access-uplink port (both ingress and egress queues)	enables or disables the high-slope and low-slope parameters for queue in addition to high-slope and low-slope, user has an option to use high-slope-ring and low-slope-ring parameters for access-uplink port egress queues
Remark policies	SAP-egress, access-uplink port egress	defines FC-to-remarking values; Not directly associated with a SAP or a port. Instead it is associated with SAP-egress policy and network qos policy
dot1p classification policy and DSCP classification policy	Access SAP-ingress and access-uplink port ingress	defines the map of dot1p bits and IP DSCP values to FC and assign the profile for the packet on access SAP-ingress and access-uplink port ingress

Policy type	Applied at…	Description
Service Ingress	Access SAP-ingress (SAP can be configured on access ports or hybrid ports)	option to define up to eight FC queues and queue parameters to define queue characteristics (For example, scheduler priority and weight, rates, and so on) option to defines up to 16 FC meters and meter parameters to define meter characteristics (For example, rates, CBS, MBS, and so on) for traffic classification, defines match criteria to map flows to the queues based on dot1p or IP DSCP criteria or MAC criteria or IP criteria
Service egress	Access SAP-egress (SAP can be configured on access ports or hybrid ports)	allocates up to eight FC queues and maps FCs to the queues defines FC-to-remarking values, through the use of remark policies defines queue parameters to define queue characteristics (For example, scheduler priority and weight, rates, and so on)
Egress rate	Access port, access-uplink port, network port, and hybrid port	configures the maximum bandwidth available for traffic sent out of a specified port
Network QoS	Network port, hybrid port, and access-uplink port	at ingress, defines up to eight FC queues and queue parameters to define queue characteristics (For example, scheduler priority and weight, rates, and so on) for traffic classification, defines match criteria using packet header bits (e.g. MPLS EXP, dot1p, IP DSCP, and so on) to map flows to the queues at egress, defines FC to remarking values, through the use of remark policies
Network queue	Network port Hybrid port Access-uplink port	allocates up to eight FC queues and maps FCs to the queues defines queue parameters to define queue characteristics (For example, scheduler priority and weight, rates, and so on)
Slope policies	Access SAP queues (both ingress and egress), Network port and hybrid port queues (both ingress and egress), and access-uplink port (both ingress and egress queues)	enables or disables the high-slope and low-slope parameters for queue in addition to high-slope and low-slope, user has an option to use high-slope-ring and low-slope-ring parameters for network port and access-uplink port egress queues
Remark policies	Access SAP-egress, network port egress (SAP can be configured on access ports or hybrid ports), hybrid port egress, and access-uplink port egress	defines FC-to-remarking values
dot1p classification policy and DSCP classification policy	Access SAP-ingress, network port ingress, hybrid port ingress, and access-uplink port ingress	defines the map of dot1p bits and IP DSCP values to FC and assign the profile for the packet received on access SAP-ingress and access-uplink port defines the map of dot1p and IP DSCP values to FC and assign the profile for packets received on network port
MPLS EXP classification policy	Network port ingress and hybrid port ingress	defines the map of MPLS EXP values to FC and assign the profile for packets received on network port
