Default Not configured
Command Mode EXEC
Usage
Information
If you do not enter an access-list name, all MAC access-list counters clear. The counter counts the
number of packets that match each permit or deny statement in an access list. To get a more recent
count of packets matching an access list, clear the counters to start at zero. To view access-list
information, use the show access-lists command.
Example
OS10# clear mac access-list counters

deny
Configures a filter to drop packets with a specific IP address.

deny [protocol-number | icmp | ip | tcp | udp] [A.B.C.D | A.B.C.D/x | any |
host ip-address] [A.B.C.D | A.B.C.D/x | any | host ip-address] [capture |
count | dscp value | fragment | log]
Parameters
● protocol-number — (Optional) Enter the protocol number identified in the IP header, from 0 to
255.
● 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.
● byte — (Optional) Count bytes the filter processes.
● dscp value — (Optional) Deny a packet based on the DSCP values, from 0 to 63.

● 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 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
10.2.0E or later
deny (IPv6)
Configures a filter to drop packets with a specific IPv6 address.
Syntax
deny [protocol-number | icmp | ipv6 | tcp | udp] [A::B | A::B/x | any |
host ipv6-address] [A::B | A::B/x | any | host ipv6-address] [capture |
count | dscp value | fragment | log]
