Located under , the Port table is used to specify the properties of the logical interfaces.
- Enable this port
- This option activates or deactivates the logical interface.
- Bridge group
- Assigns the logical interface to a bridge group to enable bridging from/to this logical interface via the LAN bridge. If assigned to a common bridge group, several logical interfaces can be addressed at once and they appear to the router to be a single interface. This can then be used for Advanced Routing and Forwarding, for example.
If the interface is removed from all bridge groups by setting none, then there is no communication between the LAN and WLAN via the LAN bridge (isolated mode). With this setting, LAN/WLAN data transfers over this interface are only possible via the router.
Note: A requirement for data transfer from/to a logical interface via the LAN bridge is the deactivation of the global "isolated mode" which applies to the whole of the LAN bridge. Furthermore, the logical interface must be assigned to a bridge group. With the setting none, no transfers can be made via the LAN bridge.
- Point-to-point port
- This item corresponds to the "adminPointToPointMAC" setting as defined in IEEE 802.1D. By default, the point-to-point setting for the LAN interface is derived from the technology and the concurrent status: However, this automatic specification can be revised if this is unsuitable for the required configuration.
Note: Interfaces in point-to-point mode have various specialized capabilities, such as the accelerated port status change for working with the Rapid Spanning Tree Protocol.
- DHCP limit
- Number of clients which can be handled by DHCP. If the limit is exceeded, the oldest entry is dropped. This feature can be used in combination with the protocol filer table to limit access to just one logical interface.
