IGX Node Configuration
Note Terminating connections is possible only at a primary slot and not at a secondary slot. See the addcon
command description in the Cisco WAN Switching Command Reference.
On multiport card sets, each primary port is connected by a Y-cable to a secondary (redundant) port.
Port 1 of the primary card set must be paired to port 1 of the secondary card set, and so on. Figure 3-4
illustrates the cabling for a multiport card set.
Figure 3-4 Y-Cables on Multiple Ports
If the secondary card set becomes active, the primary card set goes into the standby state. For the primary
card set to serve as a backup, it must be a complete set and not have failed status.
Controlling External Devices
If your system is configured to control an external device, such as a multiplexer, you can establish a
window session, any characters you type at the control terminal go to the external device for processing.
Any characters generated by the external device appear on the control terminal screen.
The window command establishes a window session. You can use this command only if the external
device connects to the local node. You can, however, enter the window command during a virtual
terminal session so that you have a window session with any external device in the network. To start a
window session:
Step 1 Access the node cabled to the device with the switch software vt command.
Step 2 Configure the port and the port function with the switch software cnfterm and cnftermfunc commands.
