DRAFT: BROCADE CONFIDENTIAL
deny (extended ACLs)
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).
fcoe Specifies to deny the Fibre Channel over Ethernet Protocol (0x8906).
ipv4 Specifies to deny the IPv4 protocol (0x0800).
count Enables counting of the packets matching the rule.
Defaults By default, no MAC ACLs are configured.

Feature Access Control List Configuration mode
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
To delete a rule from a MAC extended ACL:
