qos match statistics Command History
Usage Guidelines for the qos match statistics Command
This command does not allow a
no
form of the command. The command operates in either per-match
mode or per-class mode. Specifying one mode automatically negates the current mode.
The Cisco 10000 series router with a PRE3 supports 262,144 unique class maps per system in per-match
mode and 4,194,304 unique class maps per system in per-class mode. Per-class mode provides greater
QoS scalability.
This command is not available on the PRE2. Due to memory limitations, the PRE2 supports a maximum
of 262,000 class maps per system.
When using the
show
commands in per-class mode, the per-match statistics display with a value of zero.
In per-class mode, the per-match statistics are zero in the MIB.
Defining Match Criteria Using the match Commands
To define the classification criteria for a class map, use the
match
commands in class-map configuration
mode. The match statements you define are the criteria the router uses to classify packets. To remove a
match statement, use the
no
form of this command. The router defaults to
match-all
.
