The following table lists the various types of filters you can configure on Foundry FastIron X-Series devices.
Layer 2 Filters
Layer 2 filters control a Foundry device’s receipt of packets based on MAC address information. Foundry devices
provide the following types of Layer 2 filters:
•
MAC address filters
•
Address-lock filters
MAC Filters
MAC filters forward or drop incoming packets based on the following information:
•
Source MAC address
•
Destination MAC address
•
Encapsulation type and EtherType (optional)
A packet whose Layer 2 information matches the filter is either permitted (forwarded) or denied (dropped). You
define a MAC filter on the global level, then apply it to an interface. The filter applies only to incoming traffic on the
interface.
NOTE:
MAC filters do not block management access to the Foundry device. For example, if you apply a filter to
block a specific host, the filter blocks switch traffic from the host but does not prevent the host from establishing a
management connection to the device through Telnet. To block management access, use an Access Control List
(ACL). See “Software-Based IP Access Control Lists (ACLs)” on page 5-1.
