ServerIronADX(config)# access-list 12 deny host 209.157.22.98 log
ServerIronADX(config)# access-list 12 deny 209.157.23.0 0.0.0.255 log
ServerIronADX(config)# access-list 12 deny 209.157.24.0/24 log
ServerIronADX(config)# access-list 12 permit any
ServerIronADX(config)# ssh access-group 12
ServerIronADX(config)# write memory
Syntax: ssh access-group <num>
The <num> parameter specifies the number of a standard ACL and must be from 1 – 99.
These commands configure ACL 12, then apply the ACL as the access list for SSH access. The
device denies SSH access from the IP addresses listed in ACL 12 and permits SSH access from all
other IP addresses. Without the last ACL entry for permitting all packets, this ACL would deny SSH
access from all IP addresses.
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.
ServerIronADX(config)# access-list 12 deny host 209.157.22.98 log
ServerIronADX(config)# access-list 12 deny 209.157.23.0 0.0.0.255 log
ServerIronADX(config)# access-list 12 deny 209.157.24.0/24 log
ServerIronADX(config)# access-list 12 permit any
ServerIronADX(config)# web access-group 12
ServerIronADX(config)# write memory
Syntax: web access-group <num>
The <num> parameter specifies the number of a standard ACL and must be from 1 – 99.
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.
ServerIronADX(config)# access-list 25 deny host 209.157.22.98 log
ServerIronADX(config)# access-list 25 deny 209.157.23.0 0.0.0.255 log
ServerIronADX(config)# access-list 25 deny 209.157.24.0 0.0.0.255 log
ServerIronADX(config)# access-list 30 deny 209.157.25.0 0.0.0.255 log
ServerIronADX(config)# access-list 30 deny 209.157.26.0/24 log
ServerIronADX(config)# access-list 30 permit any
ServerIronADX(config)# snmp-server community public ro 25
ServerIronADX(config)# snmp-server community private rw 30
ServerIronADX(config)# write memory
