Configures a MAC address rule to drop traffic based on the source and destination MAC addresses.
Synopsis
deny {any | host MAC _ACL| MAC_ACL} {any | host MAC _ACL| MAC _ACL} [EtherType |arp |fcoe |
ipv4] [count]
no deny {any | host MAC _ACL| MAC_ACL} {any | host MAC _ACL| MAC _ACL} [EtherType |arp
|fcoe| ipv4]
Operands
any
Specifies any source MAC address.
host MAC_ACL
Specifies the source host MAC address for which to set deny conditions. Use
the format HHHH.HHHH.HHHH.
MAC_ACL
Specifies the source host MAC address for which to set deny conditions. Use
the format HHHH.HHHH.HHHH.
any
Specifies any destination MAC address.
host MAC_ACL
Specifies the destination host address for which to set deny conditions. Use
the format HHHH.HHHH.HHHH.
MAC_ACL
Specifies the destination host address for which to set deny conditions. Use
the format HHHH.HHHH.HHHH.
Ethertype
Specifies the protocol number for which to set the deny conditions. The
range of valid values is 1536-65535.
arp
Specifies to deny the Address Resolution Protocol (0x0806).

Description
Use this command to configure rules to match and drop traffic based on the source and
destination MAC addresses and the protocol type. You can also enable counters for a specific rule.
There are 255 ACL counters supported per port group. Use the no deny command to remove a rule
from the MAC ACL.
Usage
Guidelines
The first set of {any | host MAC_ACL | MAC_ACL} parameters is specific to the source MAC
address. The second set of {any | host MAC_ACL | MAC_ACL} parameters is specific to the
destination MAC address.
Example
To create a rule in a MAC extended ACL to drop IPv4 traffic from the source MAC address
0022.3333.4444
to the destination MAC address
0022.3333.5555
and
to
enable the counting
of packets:
switch(conf-macl-ext)#deny 0022.3333.4444 0022.3333.5555 ipv4 count
