Command History
Usage Guidelines Using the log-deny option at the end of the individual ACL entries shows the ACL number and whether
the packet was permitted or denied, in addition to port-specific information. This option causes an
information logging message about the packet that matches the dropped entry (or entries).
Examples The following example configures the an IP-ACL called aclPermit and permits IP traffic from any source
address to any destination address.
switch# config terminal
Enter configuration commands, one per line. End with CNTL/Z.
switch(config)# ip access-list aclPermit permit ip any any
operator Compares source or destination ports to the packet and has the following
options:
any = Any destination IP
eq = Equal source port
gt = Greater than and including source port
lt = Less than and including source port
range port = Source port range port-value
port port-value Specifies the decimal number (ranging from 0 to 65535) or one of the
following names to indicate a TCP or UDP port.
The TCP port names are: dns, ftp, ftp-data, http, ntp, radius, sftp, smtp, snmp,
snmp-trap, ssh, syslog, tacacs-ds, telnet, wbem-http, wbem-https, and www.
The UDP port names are: dns, ftp, ftp-data, http, ntp, radius, sftp, smtp,
snmp, snmp-trap, ssh, syslog, tacacs-ds, telnet, tftp, wbem-http, wbem-https,
and www.
icmp-type icmp-value Filters ICMP packets by ICMP message type. The range is 0 to 255. The
types include: echo, echo-reply, redirect, time-exceeded, traceroute, and
unreachable.
established Indicates an established connection for the TCP protocol. A match occurs if
the TCP datagram has the ACK, FIN, PSH, RST, SYN or URG control bits
set. The non-matching case is that of the initial TCP datagram to form a
connection.
tos tos-value Filters packets by the following type of service level: normal-service (0),
monetary-cost (1), reliability (2), throughput (4), and delay (8).
