Thanks for sharing your feedback!

Use this page to restrict the types of broadcast frames (and IPv6 multicast frames) that are sent to the CPU as part of performing traffic management tasks. You can specify a different management mode for each port on the unit.

Note: A LAG's management mode is only applied to the physical ports it comprises if the protection option is enabled on the LAG. Otherwise, the settings for the ports are applied to the physical ports.

To view or configure CPU OAM options

Access the page System ▶CPU OAM Options.
All local ports (including LAG ports) and their current management mode are displayed.
The total number of ports found in the system is given in the lower-left corner of the page, as well as the index values of the ports currently displayed on-screen (for example, [1-18] of 18). Use the page navigation links in the lower-right corner of the page to move between the pages of results.
To update a port's settings, click its name under the Port Name heading.
The CPU OAM Options page is displayed.
Configure the management mode by making a selection from the drop-down list, then click Apply.

For more information on specific parameters, refer to the following table.

CPU OAM Options (System ▶CPU OAM Options)

Parameter	Description
Port Name	The name of the port you selected in the previous page appears here. You cannot modify this value.
Management Mode	Make a selection from the drop-down list to indicate how sending broadcast and multicast frames to the CPU should be handled. Note: Choosing a management mode other than Auto can create situations where you lose access to the unit. For example, ensure that your policies have been created before selecting Policy as the management mode. Auto: Allow the system to determine which broadcast and multicast frames to send to the CPU based on how the interface is configured. This is the default value and the least restrictive management mode. MAC-OUI: Only accept broadcast and multicast frames originating from source MAC addresses that contain an Accedian OUI value: 0015AD or 0024FD. Policy: No broadcast or multicast frames are allowed by default. Sending these frames to the CPU is controlled entirely via MGMT-OAM policies you create.
