permit tcp (IPv6)
Configures a filter to permit TCP packets meeting the filter criteria.
Syntax
permit tcp [A::B | A::B/x | any | host ipv6-address [eq | lt | gt | neq
| range]] [A::B | A:B/x | any | host ipv6-address [eq | lt | gt | neq
| range]] [ack | fin | psh | rst | syn | urg] [capture | dscp value |
fragment]
Parameters
● 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) Set all routes which are subject to the filter:
○ capture — (Optional) Capture packets the filter processes.
○ dscp value — (Optional) Permit a packet based on the DSCP values, from 0 to 63.
○ fragment — (Optional) Use ACLs to control packet fragments.
NOTE: The control-plane ACLs do not support the any parameter.
● host ipv6-address — (Optional) Enter the IPv6 address to use a host address only.
Default Not configured
Command Mode IPV6-ACL
Usage
Information
The no version of this command removes the filter.
Example
OS10(config)# ipv6 access-list ipv6test
OS10(conf-ipv6-acl)# permit tcp any any capture session 1

permit udp
Configures a filter that allows UDP packets meeting the filter criteria.
Syntax
permit udp [A.B.C.D | A.B.C.D/x | any | host ip-address [eq | lt | gt |
neq | range]] [[A.B.C.D | A.B.C.D/x | any | host ip-address [eq | lt | gt |
neq | range] ] [ack | fin | psh | rst | syn | urg] [capture | dscp value |
fragment]
Parameters
● A.B.C.D — Enter the IP address in dotted decimal format.
● A.B.C.D/x — Enter the number of bits that must match the dotted decimal address.
● any — (Optional) Set all routes which are subject to the filter:
○ capture — (Optional) Capture packets the filter processes.
○ dscp value — (Optional) Permit a packet based on the DSCP values, from 0 to 63.
○ fragment — (Optional) Use ACLs to control packet fragments.
○ eq — (Optional) Permit packets which are equal to.
○ lt — (Optional) Permit packets which are less than.
○ gt — (Optional) Permit packets which are greater than.
○ neq — (Optional) Permit packets which are not equal to.
○ range — (Optional) Permit packets with a specific source and destination address.
○ ack — (Optional) Set the bit as acknowledgement.
○ 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.
NOTE: The control-plane ACL supports only the eq operator.
