16- and 36-Port Ethernet Switch Module for Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series permit (access-list configuration) operator port (Optional) Defines a source or destination port. The operator can be only eq (equal). If operator is after the source IP address and wildcard, conditions match when the source port matches the defined port. If operator is after the destination IP address and wildcard, conditions match when the destination port matches the defined port. The port is a decimal number or name of a Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) port. The number can be from 0 to 65535. Use TCP port names only for TCP traffic. Use UDP port names only for UDP traffic. Defaults There are no specific conditions that permit packets in a named or numbered IP ACL. The default ACL is always terminated by an implicit deny statement for all packets. Command Modes Access-list configuration Command History Release 12.1(6)EA2 12.2(15)ZJ Modification This command was introduced. This command was implemented on the following platforms: Cisco 2600 series, Cisco 3600 series, and Cisco 3700 series routers. Usage Guidelines Use this command after the ip access-list global configuration command to specify permit conditions for a named or numbered IP ACL. You can specify a source IP address, destination IP address, IP protocol, TCP port, or UDP port. Specify the TCP and UDP port numbers only if protocol is tcp or udp and operator is eq. Note For more information about configuring IP ACLs, refer to the "Configuring IP Services" chapter in the Cisco IOS IP Configuration Guide, Release 12.2. Examples The following example shows how to create an extended IP ACL and configure permit conditions for it: Switch(config)# ip access-list extended Internetfilter2 Switch(config-ext-nacl)# permit host 36.10.10.5 any Switch(config-ext-nacl)# permit host 192.1.10.8 any The following is an example of a standard ACL that sets permit conditions: ip access-list standard Acclist1 permit 192.5.34.0 0.0.0.255 permit 128.88.10.0 0.0.0.255 permit 36.1.1.0 0.0.0.255 Cisco IOS Release 12.2(2)XT, 12.2(8)T, and 12.2(15)ZJ 205
