Transaction Rate Limit (TRL)

1

Saving a TRL configuration

The following applies to saving a TRL config:

•

the startup-config cannot store 15,000 IPv4 and 15,000 IPv6 rules.

•

If the total number of IPv4 and IPv6 rules exceeds 2500, issuing the write mem command 
stores the TRL rules in the “trl_conf.txt” file on the internal USB drive.

•

the policy config and global/local maximum rule count config is always stored in the 
startup-config.

Disabling the storage of TRL rules on the internal USB drive

By default, storage of TRL rules on the internal USB drive of a ServerIron ADX is enabled. You can 
disable the storage of TRL rules on the internal USB drive of a ServerIron ADX as shown.

ServerIronADX(config)# no client-trans-rate-limit usb-config-gen

Syntax: no client-trans-rate-limit usb-config-gen

NOTE

Where the storage of TRL rules on the internal USB drive of a ServerIron ADX is disabled and the 
total rules exceeds 2500, only 2500 rules would be saved in startup-config.

Transaction rate limit command reference

This section describes the syntax, semantics, and usage for each transaction rate limit command. 
This section contains the following sections: 

•

client-trans-rate-limit

Use the client-trans-rate-limit command in the global configuration mode to configure a transaction 
rate limit rule name and traffic type.

 {udp <name> | default}

icmp - Specifies ICMP transaction rate limit for client subnet.

tcp - Specifies TCP transaction rate limit for client subnet.

udp - Specifies UDP transaction rate limit for client subnet.

<name> - Specifies the name for this configuration.

default - Specifies default.
