permit udp
Congures a lter that allows UDP packets meeting the lter 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 | count | dscp value |
fragment | log]
Parameters
• 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.
• 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 lter processes.
• dscp value — (Optional) Permit 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 — (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 specic source and destination address.
NOTE
: The control-plane ACL supports only the eq operator.
Default Not congured
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 lter.
The count, byte, and log options are not supported on the S5148F-ON platform.
Example
OS10(config)# ip access-list testflow
OS10(conf-ipv4-acl)# permit udp any any capture session 1
