Assign a sequence number to a deny or permit filter in an extended IP access list while creating the filter.
Syntax
seq sequence-number {deny | permit} {ipv6-protocol-number | icmp | ip | tcp |
udp} {source mask | any | host ipv6-address} {destination mask | any | host
ipv6-address} [operator port [port]] [count [byte]] [dscp value] [order]
[fragments] [log [interval minutes] [threshold-in-msgs [count]] [monitor]
Parameters
sequence-number Enter a number from 0 to 4294967290. The range is from 1 to 65534.
deny Enter the keyword deny to configure a filter to drop packets meeting this condition.
permit Enter the keyword permit to configure a filter to forward packets meeting this criteria.
ipv6-protocol-
number
Enter a number from 0 to 255 to filter based on the protocol identified in the IP protocol
header.
icmp Enter the keyword icmp to configure an ICMP access list filter.
ip Enter the keyword ip to configure a generic IP access list. The keyword ip specifies
that the access list permits all IP protocols.
tcp Enter the keyword tcp to configure a TCP access list filter.
udp Enter the keyword udp to configure a UDP access list filter.
source Enter an IP address in dotted decimal format of the network from which the packet was
received.
mask (OPTIONAL) Enter a network mask in /prefix format (/x) or A.B.C.D. The mask, when
specified in A.B.C.D format, may be either contiguous or non-contiguous.
any Enter the keyword any to specify that all routes are subject to the filter.
host ipv6-address Enter the keyword host and then enter the IPv6 address to specify a host IP address or
hostname.
operator (OPTIONAL) Enter one of the following logical operands:
• eq = equal to
• neq = not equal to
• gt = greater than
• lt = less than
• range = inclusive range of ports (you must specify two ports for the port
parameter.)
port port (OPTIONAL) Enter the application layer port number. Enter two port numbers if you are
using the range logical operand. The range is from 0 to 65535.
The following list includes some common TCP port numbers:
• 23 = Telnet
• 20 and 21 = FTP
