Cisco Security Appliance Command Line Configuration Guide
OL-6721-01
Chapter 32 Monitoring and Troubleshooting
Troubleshooting the Security Appliance
By default, SNMP core traps are enabled (snmp). If you do not enter a trap type in the command, syslog
is the default. To enable or disable all traps, enter the all option. For snmp, you can identify each trap
type separately. See Table 32-1 on page 32-2 for a list of traps.
Step 5 To enable system messages to be sent as traps to the NMS, enter the following command:
hostname(config)# logging history
level
You must also enable syslog traps using the preceding snmp-server enable traps command.
Step 6 To enable logging, so system messages are generated and can then be sent to an NMS, enter the following
command:
hostname(config)# logging on
The following example sets the security appliance to receive requests from host 192.168.3.2 on the inside
interface.
hostname(config)# snmp-server host 192.168.3.2
hostname(config)# snmp-server location building 42
hostname(config)# snmp-server contact Pat lee
hostname(config)# snmp-server community ohwhatakeyisthee

Testing Your Configuration
This section describes how to test connectivity for the single mode security appliance or for each security
context. The following steps describe how to ping the security appliance interfaces, and how to allow
hosts on one interface to ping through to hosts on another interface.
We recommend that you only enable pinging and debug messages during troubleshooting. When you are
done testing the security appliance, follow the steps in the “Disabling the Test Configuration” section on
page 32-9.
