Configuring for Network Management Applications
Using SNMP Tools To Manage the Switch
SNMP Management Features
SNMP management features on the switch include:
■ SNMP version 1, version 2c, or version 3 over IP
■ Security via configuration of SNMP communities (page 13-11)
■ Security via authentication and privacy for SNMP Version 3 access
■ Event reporting via SNMP
• Version 1 traps
• RMON: groups 1, 2, 3, and 9
■ ProCurve Manager/Plus support
■ Standard MIBs, such as the Bridge MIB (RFC 1493), Ethernet MAU MIB
(RFC 1515), and others.
The switch SNMP agent also uses certain variables that are included in a
Hewlett-Packard proprietary MIB (Management Information Base) file. If you
are using HP OpenView, you can ensure that it is using the latest version of
the MIB file by downloading the file to the OpenView database. To do so, go
to the ProCurve Networking web site at:
www.procurve.com
Click on software updates, then MIBs.
Configuring for SNMP version 1 and 2c Access to the
Switch
SNMP access requires an IP address and subnet mask configured on the
switch. (Refer to “IP Configuration” on page 8-2.) If you are using DHCP/Bootp
to configure the switch, ensure that the DHCP/Bootp process provides the IP
address. (Refer to “DHCP/Bootp Operation” on page 8-12.)
Once an IP address has been configured, the main steps for configuring SNMP
version 1 and version 2c access management features are:
1. Configure the appropriate SNMP communities. (Refer to “SNMPv3 Com-
munities” on page 13-11.)
2. Configure the appropriate trap receivers. (Refer to “SNMP Notifications”
on page 13-17.)
In some networks, authorized IP manager addresses are not used. In this case,
all management stations using the correct community name may access the
switch with the View and Access levels that have been set for that community.
