IPV4 SOFTWARE ACCESS CONTROL LIST (ACL) COMMANDS
(ACCESS-LIST EXTENDED TCP UDP FILTER)
Mode IPv4 Extended ACL Configuration
Default Any traffic controlled by a software ACL that does not explicitly match a filter is
denied.
Usage An ACL can be configured with multiple ACL filters using sequence numbers. If the
sequence number is omitted, the next available multiple of 10 will be used as the
sequence number for the new filter. A new ACL filter can be inserted into the
middle of an existing list by specifying the appropriate sequence number.
NOTE: The access control list being configured is selected by running the access-list
(extended numbered) command or the access-list extended (named) command, with
the required access control list number, or name - but with no further parameters
selected.
Software ACLs will deny access unless explicitly permitted by an ACL action.
Example 1
[creating a list]
To add a new entry to the access-list named my-list that will reject TCP packets
from 10.0.0.1on TCP port 10 to 192.168.1.1 on TCP port 20, use the
commands:
awplus# configure terminal
awplus(config)# access-list extended my-list
awplus(config-ip-ext-acl)# deny tcp 10.0.0.1/32 eq 10
192.168.1.1/32 eq 20
<destination> The destination address of the packets. You can specify a single
host, a subnet, or all destinations. The following are the valid
formats for specifying the destination:
<ip-addr>/
<prefix>
An IPv4 address, followed by a
forward slash, then the prefix length.
This matches any destination IP
address within the specified subnet.
any Matches any destination IP address.
<destport> The destination port number, specified as an integer between 0
and 65535.
eq Matches port numbers equal to the port number specified
immediately after this parameter.
lt Matches port numbers less than the port number specified
immediately after this parameter.
gt Matches port numbers greater than the port number specified
immediately after this parameter.
ne Matches port numbers not equal to the port number specified
immediately after this parameter.
log Log the results.
