count | dscp value | fragment | log]
Parameters
● protocol-number — (Optional) Enter the protocol number identified in the IP header, from 0 to

● icmp — (Optional) Enter the ICMP address to deny.
● ip — (Optional) Enter the IP address to deny.
● tcp — (Optional) Enter the TCP address to deny.
● udp — (Optional) Enter the UDP address to deny.
● A.B.C.D — Enter the IP address in dotted decimal format.
● A.B.C.D/x — Enter the number of bits to match to the dotted decimal address.
● any — (Optional) Enter the keyword any to specify any source or destination IP address.
● host ip-address — (Optional) Enter the keyword and the IP address to use a host address only.
● capture — (Optional) Capture packets the filter processes.
● count — (Optional) Count packets the filter processes.

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 filter.
Example
OS10(config)# ip access-list testflow
OS10(conf-ipv4-acl)# deny udp any any
Supported
Releases

count | dscp value | fragment | log]
Parameters
● protocol-number — (Optional) Enter the protocol number identified in the IP header, from 0 to
