8.3 PC and UNIX Workstation Requirements
To use CTC for the ONS 15454, your computer must have a web browser with the correct Java Runtime
Environment (JRE) installed. The correct JRE for each CTC software release is included on the
Cisco ONS 15454 software CD. If you are running multiple CTC software releases on a network, the
JRE installed on the computer must be compatible with the different software releases.
You can change the JRE version on the Preferences dialog box JRE tab. When you change the JRE
version on the JRE tab, you must exit and restart CTC for the new JRE version to take effect.

1. Software Releases 4.0 and later notify you if an older version of the JRE is running on your PC or UNIX workstation.
Note To avoid network performance issues, Cisco recommends managing a maximum of 50 nodes
concurrently with CTC. The 50 nodes can be on a single DCC or split across multiple DCCs. Cisco does
not recommend running multiple CTC sessions when managing two or more large networks.
To manage more than 50 nodes, Cisco recommends using Cisco Transport Manager (CTM). If you do
use CTC to manage more than 50 nodes, you can improve performance by adjusting the heap size; see
the "General Troubleshooting" chapter of the Cisco ONS 15454 Troubleshooting Guide. You can also
create login node groups; see the "Connect the PC and Log Into the GUI" chapter of the
Cisco ONS 15454 Procedure Guide.
