Rate Limiting
187500 conform-action set-prec-transmit 5 exceed-action drop
The following rule applies to traffic that matches ACL 103. Like the previous rule, this rule drops packets received
after the maximum number of conforming packets have been received. However, notice that this rule applies to
traffic in the outbound direction.
HP9300(config-if-e1000-1/1)# rate-limit output access-group 103 1000000 100000
100000 conform-action set-prec-transmit 5 exceed-action drop
The following command configures a rule for all Ethernet traffic that does not match one of the ACLs used in the
rules above.
HP9300(config-if-e1000-1/1)# rate-limit input 4000000 80000 120000 conform-action
set-prec-transmit 5 exceed-action drop
When you make configuration changes, make sure you save them to the startup-config file. If the system resets
for any reason or you reload the software, the configuration changes you make are reinstated only if they have
been saved to the startup-config file. Enter the following command to save configuration changes:
HP9300(config-if-e1000-1/1)# write memory
You can enter this command from any configuration level of the CLI.
Commands for “Adaptive Rate Policy for a Specific MAC Address”
To configure the Adaptive Rate Limiting application described in “Adaptive Rate Policy for a Specific MAC
Address” on page 4-7, enter the following commands.
The following command configures a rate limit ACL to characterize the traffic. In this case, the rate policy is for a
specific host, so the rate limit ACL specifies a host MAC address.
HP9300(config)# access-list rate-limit 100 aaaa.bbbb.cccc
The following command changes the CLI to the configuration level for virtual interface ve2.
HP9300(config)# interface virtual ve2
The following command configures rule for inbound traffic that matches the rate limit ACL configured above. The
rule sends traffic that conforms to the Normal Burst Size and drops traffic received after the maximum number of
conforming bytes have been received.
The Average Rate for the rule is 8000000 bps. The Normal Burst Size is 640000 bytes, and the Excess Burst Size
is 800000 bytes. Based on the Average Rate and Normal Burst Size values, the Committed Time Interval is 6.4/
10ths of a second, or about 2/3 seconds.
HP9300(config-ve-2)# rate-limit input access-group ratelimit 100 4000000 320000
400000 conform-action transmit exceed-action drop
The following command saves the configuration changes:
HP9300(config-ve-2)# write memory
Commands for “Adaptive Rate Policy for a Port-Based VLAN”
To configure the Adaptive Rate Limiting application described in “Adaptive Rate Policy for a Port-Based VLAN” on
page 4-8, enter the following commands.
The following command changes the CLI to the configuration level for port-based VLAN 2.
HP9300(config)# vlan 2
The following command configures a rule for all inbound Ethernet traffic on the VLAN’s ports. The rule applies to
all Ethernet packets that come into the device on a port in VLAN 2.
HP9300(config-vlan-2)# rate-limit input 10000000 125000 187500 conform-action set-
prec-transmit 5 exceed-action set-prec-transmit 0
The following command saves the configuration changes:
HP9300(config-vlan-2)# write memory
