Is there any limitation of MAC address per bridge?


Hi All,

I am using sudo cl-resource-query to see maximum MAC addresses that switch supports. For example, Dell 4048-ON supports 32768 maximum MAC addresses. Does anyone know how many MAC addresses that it supports per bridge on Cumulus Linux?

Thanks,
Try Chhay

I've never heard any explicit limitation around MAC addresses per bridge. It should be possible to put all of them on a single bridge.
Thanks Eric for your reply. That's good suggestion to put all of them on the single bridge but traditional bridge has been used in order to apply policer on each bridge. So if it's using traditional bridge, is there any limitation of MAC addresses per bridge? or any way to limit MAC address per bridge? Let's say 10 MAC addresses per bridge.

There are no configurable MAC limits per bridge. This feature might otherwise be called port security.
