RackSwitch G8000 Application Guide

Using SNMP

Blade OS provides SNMP v1.0 and SNMP v3.0 support for access through any network man- agement software, such as IBM Director or HP-OpenView.

SNMP v1, v2

To access the SNMP agent on the G8000, the read and write community strings on the SNMP manager should be configured to match those on the switch. The default read community string on the switch is public and the default write community string is private.

The read and write community strings on the switch can be changed using the following com- mands on the CLI:

RS G8000 (config)# snmp-server read-community <1-32 characters>

and

RS G8000 (config)# snmp-server write-community <1-32 characters>

The SNMP manager should be able to reach any one of the IP interfaces on the switch.

SNMP v3.0

SNMPv3 is an enhanced version of the Simple Network Management Protocol, approved by the Internet Engineering Steering Group in March, 2002. SNMP v3.0 contains additional secu- rity and authentication features that provide data origin authentication, data integrity checks, timeliness indicators and encryption to protect against threats such as masquerade, modifica- tion of information, message stream modification and disclosure.

SNMPv3 ensures that the client can use SNMPv3 to query the MIBs, mainly for security.

For more information on SNMP MIBs and the commands used to configure SNMP on the switch, see the RackSwitch G8000 Command Reference.

Default configuration

The G8000 has two SNMP v3 users by default. Both of the following users have access to all the MIBs supported by the switch:

1)username 1: adminmd5 (password adminmd5). Authentication used is MD5.

2)username 2: adminsha (password adminsha). Authentication used is SHA.
