Examples
The following example shows how to enable the ACE to send server load-balancing traps to the host at
IP address 192.168.1.1 using a community string:
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

Enabling the IETF Standard for SNMP linkUp and linkDown Traps

This section describes how to configure the ACE to send the Internet Engineering Task Force (IETF)
standards-based implementation for linkUp and linkDown traps (as outlined in RFC 2863) rather than
send the Cisco implementation of linkUp and linkDown traps to the NMS. By default, the ACE sends

Purpose
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,
–
serverfarm, or vserver keyword to enable server
load-balancing notifications. This selection generates a
notification if the following state change occurs:
The real server changes state (up or down) due to user
intervention, ARP failures, or probe failures.
The server farm changes state because all real servers in
the server farm are down.
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.
Disables SNMP server notifications.
(Optional) Copies the running configuration to the startup
configuration.
