any | host ipv6-address [operator]] [ack | fin | psh | rst | syn | urg]
[capture | count | dscp value | fragment | log]
Parameters
• A::B — Enter the IPv6 address in hexadecimal format separated by colons.
• A::B/x — Enter the number of bits to match to the IPv6 address.
• any — (Optional) Enter the keyword any to specify any source or destination IP address.
• host ipv6-address — (Optional) Enter the keyword and the IPv6 address to use a host address only.
• ack — (Optional) Set the bit as acknowledgement.
• fin — (Optional) Set the bit as nish—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 lter processes.
• count — (Optional) Count packets the lter processes.
• byte — (Optional) Count bytes the lter 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.
• operator — (Optional) Enter a logical operator to match the packets on the specied 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 specied port numbers.
Default
Not congured
Command Mode IPV6-ACL
Usage Information OS10 cannot count both packets and bytes; when you use the count byte options, only bytes increment. The
no version of this command removes the lter.
The count, byte, and log options are not supported on the S5148F-ON platform.
Example
OS10(config)# ipv6 access-list ipv6test
OS10(conf-ipv6-acl)# deny udp any any capture session 1
