Alteon OS Application Guide

Using SNMP

Alteon 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 v1.0

To access the SNMP agent on the GbESM, 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:

>> /cfg/sys/ssnmp/rcomm

and

>> /cfg/sys/ssnmp/wcomm

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

For the SNMP manager to receive the traps sent out by the SNMP agent on the switch (SNMPv1 only), configure the trap host on the switch with the following command:

/cfg/sys/ssnmp/trsrc <1-250>

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.

To access the SNMP v3.0 menu, enter the following command in the CLI:

>> # /cfg/sys/ssnmp/snmpv3
