Enterasys Networks ENTERASYS ATX manual Bridge Port Configuration, Ring Speed, Local Switching

The ATX Switch Chassis View

To set broadcast protection:

1.In the Thresh Number field enter the maximum number of multicast packets that can be transmitted through the port during each time interval. The default number of multicast packets that can be received in the specified time interval is 600,000.

2.In the Thresh Time field enter number hours, minutes, seconds in which the maximum number of multicast packets must be transmitted in order for the threshold to be reached.The default time interval is 10 seconds.

Ring Speed

If the port is a token ring port, you can set the Ring Speed from this window. Token Ring networks can operate at either 4 or 16 Mbps. All devices connected to the same network must operate at the same speed. You can set the speed used on this port by clicking on the appropriate Ring Speed selection button, either 4 or 16. If the port is not a token ring port, the ring speed options will be grayed out.

Local Switching

If the port is a token ring or fast ethernet port you can use local switching so that the frames may be bridged between token ring ports on the same board at higher throughput and lower latency than is otherwise possible. Address statistics will not reflect any frames forwarded in this manner. This applies to only transparent bridging and must be enabled on both the entry and exit port. The options for this field are On or Off. Click on the appropriate Local Switching selection button to select On or Off; the default value is Off. If the port is not a token ring port, and/or does not support local switching, the local switching options will be grayed out.

After you have configured all the fields in this window, click on Set to set the configuration on the current port.

Bridge Port Configuration

The Bridge Configuration window allows you to configure bridging over an individual port. You can configure the bridge mode that this port will use and whether or not the port will transmit BPDUs. If the port is configured for source route bridging or source route transparent bridging you can also configure source routing for the port in the lower half of the window.

To access Bridge Port Configuration:

1.Click on the appropriate Port button. A menu will appear.

2.Drag down to Bridge Configuration and release. The Bridge Configuration window, Figure 2-11,will be displayed.
