Chapter 8 Configuring SNMP Configuring SNMP Notifications - snmp-Sends SNMP notifications. When you specify the snmp keyword, you can specify a notification_option value. - syslog-Sends error message notifications (Cisco Syslog MIB). Specify the level of messages to be sent with the logging history level command. Note To enable system messages to be sent as traps to the NMS, you can specify the logging history command. You must also enable syslog traps by using the snmp-server enable traps command. See the Cisco 4700 Series Application Control Engine Appliance System Message Guide for details. - virtual-context-Sends virtual context change notifications. This keyword appears only in the Admin context. • notification_option-(Optional) Enables the following SNMP notifications: - When you specify the snmp keyword, specify the authentication, coldstart, linkdown, or linkup keyword to enable SNMP notifications. This selection generates a notification if the community string provided in the SNMP request is incorrect, or when a VLAN interface is either up or down. The coldstart keyword appears only in the Admin context. - When you specify the slb keyword, specify the real or vserver keyword to enable server load-balancing notifications. This selection generates a notification if the following occurs: • The real server changes state (up or down) due to user intervention, ARP failures, or probe failures. • The virtual server changes state (up or down). The virtual server represents the servers behind the content switch in the ACE to the outside world and consists of the following attributes: the destination address (can be a range of IP addresses), the protocol, the destination port, or the incoming VLAN. For example, to enable the ACE to send server load-balancing traps to the host at IP address 192.168.1.1 by using the community string public, enter: host1/Admin(config)# snmp-server host 192.168.1.1 host1/Admin(config)# snmp-server community SNMP_Community1 group Network-Monitor host1/Admin(config)# snmp-server enable traps slb real OL-11157-01 Cisco 4700 Series Application Control Engine Appliance Administration Guide 8-35
