Token RingOne of the major technologies battles of the 80’s and 90’s was Token Ring vs. Ethernet. Having said that, the actual ring on which the token is circulated is a logical ring inside of the MAU. Use the show operating-config privileged exec command to decide which speed is specified on the router. Token Ring vendors tried to increase the speed of the technologies to 100Mbps to overcome the Ethernet positive aspects, but by the time they did at the turn of the century, it was also late.

Two ports are Ring In (RI) and Ring Out (RO) which let numerous MAUs to be linked to each other. The subsequent station in the ring will see the token, and either capture it and send its personal information or it may just repeat the token. If no such frames are received within 18 seconds, then the station reports a failure to open and de-inserts from the ring.

The supply node removes the packet from the cable and releases the token so that a different node may possibly transmit. The other connectors are labeled RI (ring in) and RO (ring out) The RI and RO connectors are made use of to connect a number of 8228s to kind bigger networks.

The node need to quit transmitting after ten milliseconds and wait for the token to come around once again if it has much more information to send. Figure 4.two gives a diagram of a Token-Ring network and the logical ring offered by the … Read the rest >>>>
