3.1.1 Cisco IOS Devices
This section describes the steps that should be performed to set up Cisco IOS devices for
network management.

Note: All steps may not be required, and some steps can be expanded with more functionality.
After performing these steps, save the configuration to nonvolatile random-access
memory (NVRAM) by using one of the following commands:

3.1.1.1 SNMP v2 Community Strings
Operations Manager can use SNMP v2 read community strings to retrieve fault and
performance information from the devices. Some of the features in Operations Manager
(Node-to-Node test, Survivable Remote Site Telephony Monitoring, and Phone Status
tests) also require SNMP write community strings to configure IP SLA (formerly known
as the Service Assurance Agent) on certain devices. If you intend to use these features, be
sure to configure SNMP write community strings on these devices. All SNMP
community strings must match on the devices and in the Operations Manager default
credentials repository.
To configure SNMP v2 community strings on a Cisco IOS device, use the following
global configuration commands:

To configure SNMP v2 community strings on a Cisco IOS device, use the following
global configuration commands:
snmp-server community
<read-community-string> RO
snmp-server community <
write-community-string> RW
These commands ensure that the device can be identified and that inventory can be
carried out.
For Cisco CallManager, Cisco Unity, and other standard IP telephony OS voice
applications, the Windows SNMP Service must be enabled and configured with a read
only (RO) community string.

3.1.1.2 SysName Variable
The system name must be unique on every Cisco IOS device for network services to
discover all Cisco IOS devices on the network. Network services use this variable to
identify each device through Cisco Discovery Protocol. If this value is duplicated on any
devices, network services discover only one of the devices. On Cisco IOS software, the
domain name also affects the sysName.
To set the sysName variable on a Cisco IOS device, use the following global
configuration command:
discover all Cisco IOS devices on the network. Network services use this variable to
identify each device through Cisco Discovery Protocol. If this value is duplicated on any
devices, network services discover only one of the devices. On Cisco IOS software, the
domain name also affects the sysName.
To set the sysName variable on a Cisco IOS device, use the following global
configuration command:
hostname
<name>
