QoS Resource Usage and Monitoring on 3400cl/6400cl

Switches

QoS, ACLs, multicast protocols, and Rate-Limiting configurations on the
3400cl/6400cl switches use rule resources on a per-port basis. Per-Port rule
usage is reserved as shown below:

Feature
1
QoS and Rate-Limiting
2
ACLs and IGMP
1
Configuring Rate-Limiting on a port uses one per-port rule on that port.
2
Configuring IGMP on any static VLAN uses one per-port ACL mask on all ports.
Table 8-10 describes rule resource use for each QoS classifier type.

When the ToS Diff-Services mode is enabled, each codepoint (DSCP) policy configured in
the DSCP map and each (inbound) codepoint assigned to a DSCP policy use one rule per-
port. When this mode is disabled, all rules used by the ToS Diff-Services option, including
any DSCP policies configured in the DSCP map, become available for other uses.
2
Enabling source-port QoS and rate-limiting on the same port uses one rule.
