13.1.2.2.7 police
Command: police <rate-kbps> <burst-kbyte> [exceed-action {drop |
policed-dscp-transmit}]
no police <rate-kbps> <burst-kbyte> [exceed-action {drop |
policed-dscp-transmit}]
Function:
Configure a policy to a classified traffic; the “
no police <rate-kbps>
<burst-kbyte> [exceed-action {drop | policed-dscp-transmit}]
” command
deletes the specified policy.
Parameter: <rate-kbps>
is the average baud rate (in kb/s) of classified traffic, range from
1,000 to 10,000,000;
exceed-action drop
means drop packets when specified
speed is exceeded;
exceed-action policed-dscp-transmit
specifies to mark
down packet DSCP value according to
policed-dscp
mapping when specified
speed is exceeded.
Default:
There is no policy by default.
Command mode: Policy class map configuration Mode
Usage Guide:
The ranges of
<rate-kbps>
and
<burst-kbyte>
are quite large, if the
setting exceeds the actual speed of the port, the policy map applying this
policy will not bind to switch ports.
Example:
Set the bandwidth for packets that matching c1 class rule to 20 MB/s, with a
burst value of 2 MB, all packets exceed this bandwidth setting will be dropped.
