IPR Card Descriptions | IPR Card |
The IPR will automatically determine when to Bridge packets and when to route them, based on the MAC destination address in the Ethernet header.
IPR will forward packets matching an entry in the addresses table, configured manually by the user. In addition, LAN broadcasts will be forwarded on all bridge PVCs. No spanning tree or learning algorithms is supported.
IPR will forward Ethernet and 802.3 packets regardless of the upper level protocol: IP DECnet, SNA, AppleTalk, etc. Bridging function is completely “transparent” at IP level, there is no changes to IP address or any other information in the IP header. When accessing the IPR itself, packets will be exchanged in the format as specified in the “encapsulation” setting for the Ethernet port.
The WAN interface is standard encapsulation of Ethernet/802.3 over Frame Relay (RFC 1490).
IPR will provide the capability to deliver IP packets to the CPU hosting the IPR. Assuming an average frame of 256 bytes, IPR maintains LAN to WAN (and WAN to LAN) throughput of 2.048 Mbps.
8.2.1.1Card Jumpers/Switch Settings
The IPR card does not have any jumpers or switches on its motherboard.
8.2.2Installing the IPR Cards
Insert the IPR 10B2 or IPR 10BT card into one of the server card chassis slots (P1 to P3). The system can accommodate up to three server cards.
