Page 62: Network Layer
60 | Product Architecture Network Layer Packet Routing Aprisa SR+ is a standard static IP router which routes and forwards IP packet based on standard IP address and routing table decisions. Aprisa SR+ router mode (see figure below), enables the routing of IP packets within the Aprisa SR+ wireless network and in and out to the external router / IP RTUs devices connected to the Aprisa SR+ wired Ethernet ports. -
Page 63: Static Ip Router
Product Architecture | 61 Static IP Router The Aprisa SR+ works in the point-to-multipoint (PMP) network as a standard static IP router with the Ethernet and wireless / radio as interfaces and serial ports using terminal server as a virtual interface. The Aprisa SR+ static router is semi-automated operation, where the routing table is automatically created in the base station and populated with routes to all remotes and repeater stations in the network during the registration process and vice versa, where the routing table is automatically created in remote... - Page 64 62 | Product Architecture Static IP Router – Human Error Free To ensure correct operation, the Aprisa SR+ router base station alerts when one (or more) of the devices is not configured for router mode or a duplicated IP is detected when manually added. When the user changes the base station IP address / subnet, the base station sends an ARP unsolicited announcement message and the remotes / repeaters auto-update their routing table accordingly.

64 | Product Architecture VLAN Bridge Mode Description General – Aprisa SR+ VLAN Bridge Aprisa SR+ works in the point-to-multipoint (PMP) network as a standard VLAN bridge with the Ethernet and wireless / radio as interfaces and serial ports using terminal server as a virtual interface. The Aprisa SR+ is a standard IEEE 802.1q VLAN bridge, where the FDB table is created by the bridge learning / aging process. - Page 67 Product Architecture | 65 VLANs – Single, Double and Trunk VLAN ports The Aprisa SR+ supports single VLAN (CVLAN), double VLAN (SVLAN) and trunk VLAN. A single VLAN can be used to segregate traffic type. A double VLAN can be used to distinguish between Aprisa SR+ sub-networks (base-repeater-remote), where the outer SVLAN is used to identify the sub-network and the CVLAN is used to identify the traffic type.
