Introduction

This document provides EAA configuration examples.

Prerequisites

The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

This document assumes that you have basic knowledge of EAA.

Example: Configuring an interface event monitor policy by using Tcl

Network configuration

Configure a monitor policy to monitor the incoming traffic statistic on Ten-GigabitEthernet 3/0/1.

Trigger the policy when the following events occur:

·     The traffic statistic reaches or exceeds the start threshold (500000000 bps) for the first time.

·     The traffic statistic reaches or exceeds the start threshold each time after it reaches or exceeds the restart threshold (200000000 bps).

Configure the policy to execute the following actions when it is triggered:

·     Sends the message "XGE3/0/1 input rate exceeded 500000000bps" with a priority of 1 from logging facility local1.

·     Displays the current CPU usage statistics, and saves the statistics to the file XGE0_info.txt.

·     Displays information about Ten-GigabitEthernet 3/0/1, and saves the information to the file XGE0_info.txt.

Example: Configuring an interface event monitor policy from the CLI

Network configuration

Configure a monitor policy to monitor the incoming traffic statistic on Ten-GigabitEthernet 3/0/1.

Trigger the policy when the following events occur:

·     The traffic statistic reaches or exceeds the start threshold (500000000 bps) for the first time.

·     The traffic statistic reaches or exceeds the start threshold each time after it reaches or exceeds the restart threshold (200000000 bps).

Configure the policy to execute the following actions when it is triggered:

·     Sends the message "XGE3/0/1 input rate exceeded 500000000bps" with a priority of 1 from the logging facility local1.

·     Displays the current CPU usage statistics, and saves the statistics to the file XGE0_info.txt.

·     Displays information about Ten-GigabitEthernet 3/0/1, and saves the information to the file XGE0_info.txt.

To conserve system resources, limit the policy runtime to 30 seconds. When the runtime is reached, the system stops executing the policy even if the execution is not finished.

Applicable hardware and software versions

The following matrix shows the hardware and software versions to which this configuration example is applicable:

 

Hardware	Software version
S12500G-AF	Release 8053P05 and later
S12500CR	Release 8053P05 and later
S10500X-G	Release 7753P05 and later
S7500X-G	Release 7753P05 and later

 

Restrictions and guidelines

When you configure a CLI-defined policy, follow these restrictions and guidelines:

·     A monitor policy can contain only one event and one runtime setting. If the monitor policy already contains an event or runtime setting, the new setting replaces the old setting.

·     A new action overwrites the previous action with the same ID.

·     You must execute the commit command for a CLI-defined policy to take effect. After changing the settings (such as the event, runtime, CLI action, and user role configurations) in the policy, you must re-execute this command for the changes to take effect.

·     For EAA to execute an action in a monitor policy, you must assign the policy the user role that has access to the action-specific commands and resources. If EAA lacks access to an action-specific command or resource, EAA does not perform the action and all the subsequent actions.

·     You cannot assign a monitor policy user roles that have higher privilege than the user roles you are logged in with.

Example: Configuring a track event monitor policy from the CLI

Network configuration

As shown in Figure 1, Device A has established BGP sessions with Device D and Device E. Traffic from Device D and Device E to the Internet is forwarded through Device A.

Configure a CLI-defined EAA monitor policy on Device A to disconnect the sessions with Device D and Device E when Ten-GigabitEthernet 3/0/1 connected to Device C is down. As a result, traffic from Device D and Device E to the Internet is forwarded through Device B.
