• host – The address must be for a single node.
• source-bitmask – Source address of rule must match this
bitmask.
• destination-bitmask – Destination address of rule must match
this bitmask.
• ethertype – Check the Ethernet type field.
• ethertype-bitmask – Ethernet type of rule must match this
bitmask.
Default Setting
None
Command Mode
MAC Mask
Command Usage
• Packets crossing a port are checked against all the rules in the ACL until
a match is found. The order in which these packets are checked is
determined by the mask, not just the order in which the ACL rules were
entered.
• The VLAN ID field is not specified in the IP or MAC mask commands
used for VLAN ACLs. The ECN330-switch automatically appends the
VID field for these masks when the VLAN ACL is bound to an interface.
Example
The following example creates a mask that checks packet format, ignores the
source MAC address, checks the destination MAC address in MAC header, and
checks the Ethernet type field if the packet type is Ethernet II.
Console(config-mac-mask-acl)#mask pktformat any host ethertype
