Usage Information When all sequence numbers have been exhausted, this feature permits re-assigning new sequence number to
entries of an existing access-list.
seq
Assign a sequence number to a deny or permit the filter in an IPv6 access list while creating the filter.
Syntax
seq sequence-number {deny | permit} {ipv6-protocol-number | icmp | ip | tcp |
udp} {source address mask | any | host ipv6-address} {destination address | any
| host ipv6-address} [operator port [port]] [count [byte]] | [log] [monitor]
To delete a filter, use the no seq sequence-number command.
Parameters
sequence-number
Enter a number from 0 to 4294967290.
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 an IPv6 protocol number. The range is 0 to 255.
icmp Enter the keyword icmp to configure an Internet Control Message Protocol version 6
filter.
ipv6 Enter the keyword ipv6 to configure any Internet Protocol version 6 filter.
tcp Enter the keyword tcp to configure a Transmission Control protocol filter.
udp Enter the keyword udp to configure a User Datagram Protocol filter.
source address
Enter the IPv6 address of the network or host from which the packets were sent in the
x:x:x:x::x format followed by the prefix length in the /x format. The range is /0 to /128.
The :: notation specifies successive hexadecimal fields of zero.
mask
Enter a network mask in /prefix format (/x).
any Enter the keyword any to specify that all routes are subject to the filter.
host
ipv6-address
Enter the keyword host followed by the IPv6 address of the host in the x:x:x:x::x format.
The :: notation specifies successive hexadecimal fields of zero.
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 using the
range logical operand. The range is 0 to 65535.
The following list includes some common TCP port numbers:
