MAC address filters configuration notes and limitations

  • MAC address filtering on FastIron devices is performed in hardware.
  • MAC address filtering on FastIron devices differ from other RUCKUS devices in that you can only filter on source and destination MAC addresses. Other RUCKUS devices allow you to also filter on the encapsulation type and frame type.
  • MAC address filtering applies to all traffic, including management traffic. To exclude management traffic from being filtered, configure a MAC address filter that explicitly permits all traffic headed to the management MAC (destination) address. The MAC address for management traffic is always the MAC address of port 1.
  • MAC address filters do not filter Layer 2 control protocols. Layer 2 control protocols, such as STP and LACP, are processed by the device even when a "Deny All" MAC address filter has been applied on the interface.
  • MAC address filtering cannot be applied on management interface for all platforms.
  • The number of MAC address filters that you can configure in an ICX 7150 stack is less than that in other platforms.

The following configuration notes apply to RUCKUS Layer 3 devices:

  • MAC address filters apply to both switched and routed traffic. If a routing protocol (for example, OSPF) is configured on an interface, the configuration must include a MAC address filter rule that allows the routing protocol MAC and the neighbor system MAC address.
  • You cannot use MAC address filters to filter Layer 4 information.
  • MAC address filters are supported on tagged ports in the Layer 3 software images.
