Restrictions and Limitations
• To minimize the impact on system performance and network traffic:
– Only one window session per IGX node is supported.
– The URM Cisco IOS console output to the IGX operates at a maximum of 9600 baud.
• A window session can access only one URM at a time. To access a different URM, close the existing
window and open a new one.
• When a window session is active, other configuration and system-impacting commands (such as the
resetcd and addtrk commands) are blocked for other users who are logged in to the same IGX.
• The window session automatically closes if the active NPM and standby NPM are switched. You
can open a new window session after the control card switch is complete. You do not need to
reconfigure the window session parameters, such as the escape string and command inactivity
timeout. The active and standby NPMs may be switched for one of the following reasons:
– You enter the switchcc command.
– The active NPM fails and causes a “hard switchcc.”
Tasks
The following tasks are required to use the window session feature:
• Task 1: Configuring the URM Cisco IOS CLI Window Feature
• Task 2: Opening the URM Cisco IOS CLI Window Session
• Task 3: Terminating the URM Cisco IOS CLI Window Session
