Configuring Network Management
This section describes how to manage the CSM on the network and contains these sections.

Configuring SNMP Traps for Real Servers
When enabled, an SNMP trap is sent to an external management device each time a real server changes
its state (for example, each time a server is taken in or out of service). The trap contains an object
identifier (OID) that identifies it as a real-server trap.
Note The real server trap OID is 1.3.6.1.4.1.9.9.161.2
The trap also contains a message describing the reason for the server state change.
Use the snmp-server enable traps slb ft command to either enable or disable fault-tolerant traps
associated with the SLB function of the Catalyst 6500 switch. A fault-tolerant trap deals with the fault
tolerance aspects of SLB. For example, when fault-tolerant traps are enabled and the SLB device detects
a failure in its fault-tolerant peer, it sends an SNMP trap as it transitions from standby to active.
To configure SNMP traps for real servers, perform this task:
Configuring the XML Interface
In previous releases, the only method available for configuration of the CSM was the IOS command line
interface. With XML, you can configure the CSM using a Document Type Definition or DTD. Refer to
Appendix C, “CSM XML Document Type Definition” for a sample of an XML DTD.
Command Purpose
Step 1
Router (config)# snmp-server
community public
Defines a password-like community string sent with the
notification operation. The example string is public.
Step 2
Router (config)# snmp-server
host host-addr
Defines the IP address of an external network management device
to which traps are sent.
Step 3
Router (config)# snmp-server
enable traps slb csrp
Enables SNMP traps for real servers
