Add Rule
◆ Policy Name – Name of policy map.
◆ Class Name – Name of a class map that defines a traffic classification upon
which a policy can act. A policy map can contain up to 32 class maps.
◆ Action – This attribute is used to set an internal QoS value in hardware for
matching packets.
■
Set CoS – Configures the service provided to ingress traffic by setting an
internal CoS value for a matching packet (as specified in rule settings for a
class map). (Range: 0-7)
See Table 10, “Default Mapping of CoS/CFI Values to Queue/CFI,” on
page 215).
■
Set IP DSCP – Configures the service provided to ingress traffic by
modifying the internal IP DSCP value for a matching packet (as specified in
rule settings for a class map). (Range: 0-63)
See Table 11, “Default Mapping of DSCP Values to Queue/CFI,” on
page 217).
◆ Meter – Check this to define the maximum throughput.
◆ Meter Mode (Rate Limit) – Applies rate limiting to ingress or egress ports. This
function allows the network manager to control the maximum rate for traffic
received or transmitted on an interface. Rate limiting is configured on
interfaces at the edge of a network to limit traffic into or out of the network.
Packets that exceed the acceptable amount of traffic are dropped.
◆ Rate – Sets the rate limit level. (Range: 16 - 1000000 kbits per second)
