6Gbit/s FD. 6-port GE card is line-rate. That's for classic 4500 chassis and SupIV/SupV. For Sup6E and 4500E chassis and linecards, you have 24Gbit/s FD. > And what about Cat6500 and Sup32 ? How much Gbps per slot and half-duplex > or full-duplex ? Without switch-fabric all cards share a 32Gbit/s bus, thats essentially 16Gbit/s FD. However, it is split into DBus (Data Bus), RBus (Results Bus) and EoBC (Ethernet Out of Band Connection). Every line card needs to gain access to the bus to send data. Data sent by linecards is copied to every linecard in the system, and when decision is made by Supervisor - cards get info what should they do with the packet they saw a moment ago on the bus. -- "Don't expect me to cry for all the | Łukasz Bromirski reasons you had to die" -- Kurt Cobain | http://lukasz.bromirski.net _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
