3Com Switch 7750 Configuration Guide

Controlling Network Management Users by Source IP Addresses 79
Controlling Network
Management Users by
Source IP Addresses
You can manage a 3Com series Ethernet switch through network management
software. Network management users can access switches through SNMP.
You need to perform the following two operations to control network
management users by source IP addresses.
■ Defining an ACL
■ Applying the ACL to control users accessing the switch through SNMP
Prerequisites The controlling policy against network management users is determined, including
the source IP addresses to be controlled and the controlling actions (permitting or
denying).
Controlling Network
Management Users by
Source IP Addresses
Controlling network management users by source IP addresses is achieved by
applying basic ACLs, which are numbered from 2000 to 2999. For defining an
ACL, refer to “Defining Basic ACLs” on page 641.
Table 38 Control network management users by source IP addresses
Operation Command Description
Enter system view system-view -
Create a basic ACL or
enter basic ACL view
acl { number acl-number | name
acl-name basic }
[ match-order { config | auto }]
As for the acl number
command, the config
keyword is specified by
default.
Define rules for the ACL rule [ rule-id ]{permit | deny }
[ source { source-addr wildcard |
any } | fragment | time-range
time-name ]*
Required
Quit to system view quit -
Apply the ACL while
configuring the SNMP
community name
snmp-agent community { read |
write } community-name
[[mib-view view-name ] | [ acl
acl-number ]]*
Optional
By default, SNMPv1 and
SNMPv2c use community
name to access.
Apply the ACL while
configuring the SNMP
group name
snmp-agent group { v1 | v2c }
group-name [ read-view
read-view ] [ write-view
write-view ] [ notify-view
notify-view ] [ acl acl-number ]
sn
mp-agent group v3 group-name
[ authentication | privacy ]
[ read-view read-view ]
[ write-view write-view ]
[ notify-view notify-view ] [ acl
acl-number ]
Optional
By default, the
authentication mode and
the encryption mode are
configured as none for the
group.
Apply the ACL while
configuring the SNMP user
name
snmp-agent usm-user { v1 | v2c }
user-name group-name [ acl
acl-number ]
snmp-agent usm-user v3
user-name group-name
[ authentication-mode { md5 |
sha } auth-password
[ privacy-mode des56
priv-password ] [ acl acl-number ]
Optional
