This read-create EnableAdmin object nominally configures MAC address learning mode for the PVC, but its own description states the setting has no effect. An admin should not rely on this OID to change bridging behavior and should look for the actual controlling parameter elsewhere in the device, since documentation confirms it is a no-op. For example, a script that toggles this OID hoping to isolate MAC learning per PVC will observe no change in the modem's bridging table.
