permit (extended ACLs)
Configures a MAC address rule to permit traffic based on the source and destination MAC
addresses.
Synopsis permit {any | host MAC _ACL| MAC_ACL} {any | host MAC _ACL| MAC _ACL} {EtherType | arp |
fcoe | ipv4} [count]
no permit {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 a host-specific source MAC address for which to set permit
conditions. Use the format HHHH.HHHH.HHHH.
MAC_ACL Specifies any MAC address for which to set permit conditions. Use the format
HHHH.HHHH.HHHH.
any Specifies any destination MAC address.
host MAC_ACL Specifies a host-specific source MAC address for which to set permit
conditions. Use the format HHHH.HHHH.HHHH.
MAC_ACL Specifies any host address for which to set permit conditions. Use the format
HHHH.HHHH.HHHH.
Ethertype Specifies the protocol number for which to set the permit conditions. The
range of valid values is from 1536 through 65535.
arp Specifies to permit the Address Resolution Protocol (0x0806).
fcoe Specifies to permit the Fibre Channel over Ethernet Protocol (0x8906).
ipv4 Specifies to permit the IPv4 protocol (0x0800).
count Enables counting of the packets matching the filter rule.
Defaults By default, no MAC ACLs are configured.

Modes
Feature Access Control List configuration mode
Description Use this command to configure rules to match and to permit 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 permit 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.
Examples To create a rule in an extended MAC ACL to permit 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)#permit 0022.3333.4444 0022.3333.5555 ipv4 count
