SNMPv2 trap host configuration

The SNMPv2 trap host configuration is similar to the SNMPv1 trap host configuration. Wherever you specify the
model you need to specify

snmpv2

instead of

snmpv1

.

c/sys/ssnmp/snmpv3/usm 10
name "v2trap"
/c/sys/ssnmp/snmpv3/access 10

SNMPv3 trap host configuration

To configure a user for SNMPv3 traps you can choose to send the traps with both privacy and authentication, with
authentication only, or without privacy or authentication.

This is configured in the access table using the command:

/c/sys/ssnmp/snmpv3/access <x>/level

, and

/c/sys/ssnmp/snmpv3/tparam <x>

. The user in the user table should be configured accordingly.

It is not necessary to configure the community table for SNMPv3 traps because the community string is not used by
SNMPv3.

The following example shows how to configure a SNMPv3 user

v3trap

with authentication only:

/c/sys/ssnmp/snmpv3/usm 11
name "v3trap"
auth md5
authpw v3trap
/c/sys/ssnmp/snmpv3/access 11
name "v3trap"
level authNoPriv
nview "iso"
/c/sys/ssnmp/snmpv3/group 11
uname v3trap
gname v3trap
/c/sys/ssnmp/snmpv3/taddr 11
name v3trap
addr 47.81.25.66
taglist v3trap
pname v3param
/c/sys/ssnmp/snmpv3/tparam 11
name v3param
uname v3trap
level authNoPriv
/c/sys/ssnmp/snmpv3/notify 11
name v3trap
tag v3trap
