Cabletron Systems EMM-E6 manual Setting a Port’s Trunk Type, Tpxmim Channel Selection Window

Using the EMM-E6 Hub View

NOTE

To place only selected ports in stand-alone mode, you must configure all other ports so that they are connected to Channel A; those ports will remain connected to Channel A when stand-alone mode is implemented, and only those ports connected to channels B or C will be put in stand-alone.

If you have configured the ports on the TPXMIM so that they are connected to different channels, the board’s Network Connection box will display a letter representing each channel to which a TPXMIM port is connected. If the entire board is in stand-alone mode, three dashes (---) will display; if some ports are still connected to Channel A, two dashes and an A (-A-) will display.

In addition, keep in mind that most Network and Module menu selections can only provide information about a single network channel. When your TPXMIM is in multi-channel mode, making a selection from one of those menus will first bring up a channel selection window (Figure 2-15, below); click to select the appropriate channel, and the desired information will be displayed as usual.

Note that the window title indicates the menu option you have selected

Setting a Port’s Trunk Type

Station ports and trunk ports are defined by how many source addresses are communicating through that port at any given moment: if zero, one, or two addresses are communicating, the port is considered to be a station port; if three or more are communicating, the port is considered to be a trunk port.
