4 Command Line Interface Syntax [no] {permit | deny} [protocol-number | udp] {any | source address-bitmask | host source} {any | destination address-bitmask | host destination} [source-port sport [end]] [destination-port dport [end]] [no] {permit | deny} tcp {any | source address-bitmask | host source} {any | destination address-bitmask | host destination} [source-port sport [end]] [destination-port dport [end]] • protocol-number - A specific protocol number. (Range: 0-255) • source - Source IP address. • destination - Destination IP address. • address-bitmask - Decimal number representing the address bits to match. • host - Keyword followed by a specific IP address. • sport - Protocol15 source port number. (Range: 0-65535) • dport - Protocol15 destination port number. (Range: 0-65535) • end - Upper bound of the protocol port range. (Range: 0-65535) Default Setting None Command Mode Extended ACL Command Usage • All new rules are appended to the end of the list. • Address bitmasks are similar to a subnet mask, containing four integers from 0 to 255, each separated by a period. The binary mask uses 1 bits to indicate "match" and 0 bits to indicate "ignore." The bitmask is bitwise ANDed with the specified source IP address, and then compared with the address for each IP packet entering the port(s) to which this ACL has been assigned. Example This example accepts any incoming packets if the source address is within subnet 10.7.1.x. For example, if the rule is matched; i.e., the rule (10.7.1.0 & 255.255.255.0) equals the masked address (10.7.1.2 & 255.255.255.0), the packet passes through. Console(config-ext-acl)#permit 10.7.1.1 255.255.255.0 any Console(config-ext-acl)# 15. Includes TCP, UDP or other protocol types. 4-92
