Configuring for Network Management Applications
Using SNMP Tools To Manage the Switch
If you want to restrict access to one or more specific nodes, you can use the
switch’s IP Authorized Manager feature. (Refer to the
Access Security Guide
for your switch.)
C a u t i o n
For ProCurve Manager (PCM) version 1.5 or earlier (or any TopTools version),
deleting the “public” community disables some network management
functions (such as traffic monitoring, SNMP trap generation, and threshold
setting). If network management security is a concern, and you are using the
above software versions, ProCurve recommends that you change the write
access for the “public” community to “Restricted”.
Configuring for SNMP Version 3 Access to the Switch
SNMP version 3 (SNMPv3) 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. (See “DHCP/Bootp Operation” on page 8-12.)
Once an IP address has been configured, the main steps for configuring SNMP
version 3 access management features are:
1. Enable SNMPv3 for operation on the switch (Refer to “SNMP Version 3
Commands” on page 13-6)
2. Configure the appropriate SNMP users (Refer to “SNMPv3 Users” on page
13-7)
3. Configure the appropriate SNMP communities. (Refer to “SNMPv3 Com­
munities” on page 13-11.)
4. 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 User and community name may
access the switch with the View and Access levels that have been set for that
community. If you want to restrict access to one or more specific nodes, you
can use the switch’s IP Authorized Manager feature. (Refer to the
Access
Security Guide for your switch.)
