Chapter 4 Configuring Virtual Contexts
Configuring SNMP for Virtual Contexts
After configuring basic SNMP information for a virtual context (see the “Configuring SNMP for Virtual
Contexts” section on page 4-19), you can configure other SNMP attributes such as SNMP version 2c
communities, SNMP version 3 users, trap destination hosts, and SNMP notification. The tabs for these
attributes appear below the SNMP configuration screen.
Use this procedure to configure SNMP trap destination hosts for a virtual context.
Assumption
You have configured at least one SNMP contact (see the “Configuring SNMP for Virtual Contexts”
section on page 4-19).
Procedure
Step 1 Choose Config > Virtual Contexts > context > System > SNMP.
The SNMP configuration screen appears.
Step 2 Click the Trap Destination Host tab.
The Trap Destination Host table appears.
Step 3 Click Add to add a host, or select an existing entry in the table, and then Edit to modify it.
The Trap Destination Host configuration screen appears.
Step 4 Configure the SNMP trap destination host using the information in Table 4-8.

• Click Deploy Now to deploy this configuration on the ACE appliance.
Table 4-8 SNMP Trap Destination Host Configuration Attributes
Field Description
IP Address Enter the IPv4 address of the server that is to receive SNMP notifications.
Port Enter the port to be used for SNMP notification. The default port is 162.
Version Select the version of SNMP used to send traps:
• V1—Indicates that SNMP version 1 is to be used to send traps. This option is not available for use
with SNMP inform requests.
• V2c—Indicates that SNMP version 2c is to be used to send traps.
• V3—Indicates that SNMP version 3 is to be used to send traps. This version is the most secure
model because it allows packet encryption.
Community Enter the SNMP community string or username to be sent with the notification operation. Valid entries
are unquoted text strings with no spaces and a maximum of 32 characters.
Security Level This field appears if V3 is the selected version.
Select the level of security that is to be implemented:
• Auth—Indicates that Message Digest 5 (MD5) and Secure Hash Algorithm (SHA) are to be used
for packet authentication.
• Noauth—Indicates that the noAuthNoPriv security level is to be used.
• Priv—Indicates that Data Encryption Standard (DES) is to be used for packet encryption.
