You can manage a Switch 4800G 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
■
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 is achieved by
applying basic ACLs, which are numbered from 2000 to 2999. Refer to
"Configuring an Advanced IPv4 ACL" on page 844 for information about defining
an ACL.
To do...
Enter system view
Create a basic ACL or
enter basic ACL view
Define rules for the ACL
Quit to system view
Apply the ACL while
configuring the SNMP
community name
Apply the ACL while
configuring the SNMP
group name
Apply the ACL while
configuring the SNMP user
name
n
You can specify different ACLs while configuring the SNMP community name, the
SNMP group name and the SNMP user name.
Use the command...
system-view
acl number acl-number [ match-order
{ config | auto } ]
rule [ rule-id ] { permit | deny } [ source
{ sour-addr sour-wildcard | any } |
time-range time-name | fragment |
