Syntax: [no] default exceed-action reset
Sample HTTP TRL configuration
This section describes how to configure a sample HTTP TRL configuration. This scenario describes
all the required steps for configuring HTTP TRL, with notes the optional steps. This configuration
consists of four parts:
• Creating an HTTP TRL policy with a client rate limit
• Configuring Layer 4 server load balancing
• Creating a CSW rule and policy with HTTP TRL
• Enabling Layer 7 server load balancing
Creating an HTTP TRL policy with client rate limit
To configure a HTTP TRL policy with client rate limit, follow these steps.
1. Define an HTTP TRL policy.
ServerIronADX(config)# http-trl-policy p1
Syntax: [no] http-trl-policy <policy-name>
2. Configure an HTTP TRL client rate limit.
ServerIronADX(config-http-trl-p1)# client-name c1 monitor-interval 1 10 20 0
Syntax: [no] client-name <client-name> monitor-interval <interval-value> <warning-rate>
<shutdown-rate> <holddown-interval>
3. Configure the action to take if a client exceeds the configured rate limit (optional).
ServerIronADX(config-http-trl-p1)# client-name c1 exceed-action reset
Syntax: [no] client-name <client-name> exceed-action reset
Configuring Layer 4 SLB
To configure Layer 4 SLB, follow these steps.
1. Define a real server (1) with an IP address.
ServerIronADX(config)# server real web1 1.1.1.1
Syntax: server real <real-server> <ip-address>
2. Define a real HTTP port on the real server.
ServerIronADX(config-rs-web1)# port http
Syntax: port http
3. Define a real server (2) with an IP address.
ServerIronADX(config-rs-web1)# server real web2 1.1.1.2
Syntax: server real <vip-name> <ip-address>
4. Define a real HTTP port on the real server and exit.
ServerIronADX(config-rs-web2)# port http
