NOTE
In this example, the command ssh access-group 10 could have been used to apply the ACL
configured in the example for Telnet access. You can use the same ACL multiple times.
Using an ACL to restrict Web management access
To configure an ACL that restricts Web management access to the device, enter commands such
as the following.
BigIron RX(config)# access-list 12 deny host 209.157.22.98 log
BigIron RX(config)# access-list 12 deny 209.157.23.0 0.0.0.255 log
BigIron RX(config)# access-list 12 deny 209.157.24.0/24 log
BigIron RX(config)# access-list 12 permit any
BigIron RX(config)# web access-group 12
BigIron RX(config)# write memory
Syntax: web access-group <num> | <name>
The <num> parameter specifies the number of a standard ACL, 1 – 99.
The <name> parameter specifies the standard access list name.
These commands configure ACL 12, then apply the ACL as the access list for Web management
access. The device denies Web management access from the IP addresses listed in ACL 12 and
permits Web management access from all other IP addresses. Without the last ACL entry for
permitting all packets, this ACL would deny Web management access from all IP addresses.
Using ACLs to restrict SNMP access
To restrict SNMP access to the device using ACLs, enter commands such as the following.
NOTE
The syntax for using ACLs for SNMP access is different from the syntax for controlling Telnet, SSH,
and Web management access using ACLs.
BigIron RX(config)# access-list 25 deny host 209.157.22.98 log
BigIron RX(config)# access-list 25 deny 209.157.23.0 0.0.0.255 log
BigIron RX(config)# access-list 25 deny 209.157.24.0 0.0.0.255 log
BigIron RX(config)# access-list 25 permit any
BigIron RX(config)# access-list 30 deny 209.157.25.0 0.0.0.255 log
BigIron RX(config)# access-list 30 deny 209.157.26.0/24 log
BigIron RX(config)# access-list 30 permit any
BigIron RX(config)# snmp-server community public ro 25
BigIron RX(config)# snmp-server community private rw 30
BigIron RX(config)# write memory
The commands configure ACLs 25 and 30, then apply the ACLs to community strings. ACL 25 is
used to control read-only access using the "public" community string. ACL 30 is used to control
read-write access using the "private" community string.
Syntax: snmp-server community <string> ro | rw
The <string> parameter specifies the SNMP community string the user must enter to gain SNMP
access.
