● A.B.C.D — Enter the IPv4 address in dotted decimal format.
● A.B.C.D/x — Enter the number of bits that must match the dotted decimal address.
● any — (Optional) Enter the keyword any to specify any source or destination IP address.
● host ip-address — (Optional) Enter the IPv4 address to use a host address only.
● operator — (Optional) Enter a logical operator to match the packets on the specified port number.
The following options are available:
○ eq — Equal to
○ gt — Greater than
○ lt — Lesser than
○ neq — Not equal to
○ range — Range of ports, including the specified port numbers.
● ack — (Optional) Set the bit as acknowledgment.
● fin — (Optional) Set the bit as finish—no more data from sender.
● psh — (Optional) Set the bit as push.
● rst — (Optional) Set the bit as reset.
● syn — (Optional) Set the bit as synchronize.
● urg — (Optional) Set the bit set as urgent.
● capture — (Optional) Capture packets the filter processes.
● count — (Optional) Count packets the filter processes.
● byte — (Optional) Count bytes the filter processes.
● dscp value — (Optional) Deny a packet based on the DSCP values, from 0 to 63.
● fragment — (Optional) Use ACLs to control packet fragments.
● log — (Optional) Enables ACL logging. Information about packets that match an ACL rule are logged.
Default
Not configured
Command Mode IPV4-ACL
Usage
Information
OS10 cannot count both packets and bytes; when you enter the count byte options, only bytes
increment. The no version of this command removes the filter, or use the no seq sequence-number
command if you know the filter’s sequence number.
Example
OS10(config)# ip access-list egress
OS10(conf-ipv4-acl)# seq 5 permit udp any any capture session 1 log
Supported
Releases
10.2.0E or later
seq permit udp (IPv6)
Assigns a sequence number to allow UDP IPv6 packets while creating a filter.
Syntax
seq sequence-number permit udp [A::B | A::B/x | any | host ipv6-address
[operator]] [A::B | A:B/x | any | host ipv6-address [operator]] [ack | fin
| psh | rst | syn | urg] [capture | count | dscp value | fragment | log]
Parameters
● sequence-number — Enter the sequence number to identify the route-map for editing and
sequencing number, from 1 to 16777214.
● A::B — Enter the IPv6 address in hexadecimal format separated by colons.
● A::B/x — Enter the number of bits that must match the IPv6 address.
● any — (Optional) Enter the keyword any to specify any source or destination IP address.
● host ipv6-address — (Optional) Enter the IPv6 address to use a host address only.
● operator — (Optional) Enter a logical operator to match the packets on the specified port number.
