They are presented with the graphical replica of the status LEDs that administrators would see if they were simultaneously standing in front of all the switch panels. A red LED indicates a problematic port, and administrators can use the management system to troubleshoot the disabled port. Time-consuming and laborious software upgrades. Upgrading switch software requires hours of repetitive tasks when using traditional device management. Software upgrades must be downloaded to each switch individually.
Clustering eases software upgrades.
Now, network administrators can remotely upgrade the entire LAN using the CMS Web interface from any PC on a corporate network. Cisco switch clusters have been designed and tested to support as many as 16 switches. Once a new switch is connected to an existing cluster, no other local configuration is required. Time-consuming switch moves or additions .
