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

Default configuration

Alteon OS 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. To configure an SNMP user name, enter the following command from the CLI:

>># /cfg/sys/ssnmp/snmpv3/usm 1

User Configuration:

Users can be configured to use the authentication/privacy options. The GbESM support two authentication algorithms: MD5 and SHA, as specified in the following command:

/c/sys/ssnmp/snmpv3/usm <x>/auth md5sha

1.To configure a user with name 'admin,' authentication type MD5, and authentication password of 'admin,' privacy option DES with privacy password of 'admin,' use the fol- lowing CLI commands.

>>	# /cfg/sys/ssnmp/snmpv3/usm 5
>>	SNMPv3 usmUser 5# name "admin"	(Configure ‘admin’ user type)

>>SNMPv3 usmUser 5# auth md5

>>SNMPv3 usmUser 5# authpw admin

>>SNMPv3 usmUser 5# priv des

>>SNMPv3 usmUser 5# privpw admin

2.Configure a user access group, along with the views the group may access. Use the access table to configure the group’s access level.

>># /cfg/sys/ssnmp/snmpv3/access 5

>> SNMPv3 vacmAccess 5#		name "admingrp"		(Configure an access group)
>> SNMPv3 vacmAccess 5#		level authPriv
>> SNMPv3 vacmAccess 5#		rview "iso"
>> SNMPv3	vacmAccess 5#	wview	"iso"
>> SNMPv3	vacmAccess 5#	nview	"iso"

Because the read view (rview), write view (wview), and notify view (nview) are all set to “iso,” the user type has access to all private and public MIBs.
