IGX Network Management
Step 3 Configure a 1-8 character escape sequence for the window session with the switch software
cnftermfunc command. Write the escape sequence here: ______________________.
Step 4 Determine whether the external window device is cabled to the node's control terminal port (c) or
auxiliary port (a).
Step 5 Start the window session with the switch software window command. If the external device is connected
to the auxiliary port, use window a. If the external device is connected to the control terminal port, use
window c.
Step 6 Enter commands and send data to the external device.
You might notice a slight transfer delay in transmission, because of the IGX/BPX bundling of characters
before transmitting them. Transfers are delayed until the transfer buffer is filled, or until the keyboard
has been inactive for over 50 ms.
Note While in the window session, only commands used to control the external device are recognized.
Step 7 Using the escape sequence configured in Step 3, end the window session.
Tip The default escape sequence is ^^. If the default sequence does not work and you do not know the
configured escape sequence, leave the keyboard idle for four minutes. After four minutes, the system
terminates the window session.
IGX Network Management
The following sections explain how to manage your IGX network. Managing your network involves
optimizing traffic routing and bandwidth, synchronizing the network, performing network
administration tasks, and managing jobs.
Optimizing Traffic Routing and Bandwidth
To achieve peak network performance, the routing of traffic and the use of available bandwidth is
configurable. The information used in configuring traffic routing and bandwidth is gathered from
historical network trends. The tasks required to optimize the network are specifying channel utilization
(see the “Specifying Channel Utilization” section on page 3-10), specifying the class of service
(including use of the priority bumping feature—see the “Specifying Class of Service” section on
page 3-10), and managing bandwidth.
Tip For information on the switch software commands listed in this section, see the full command
description in the Cisco WAN Switching Command Reference.
