Chapter 1      Overview
Management Options
• Apply actions from CMS to multiple ports and multiple switches at the same 
time to avoid re-entering the same commands for each individual port or 
switch. Here are some examples of globally setting and managing multiple 
ports and switches:
–
Port configuration such as speed and duplex settings
–
Port and console port security
–
NTP, STP, VLAN, and quality of service (QoS) configuration
–
Inventory and statistic reporting and link- and switch-level monitoring 
and troubleshooting
–
Group software upgrade
• View a topology of interconnected devices to identify existing switch clusters 
and eligible switches that can join a cluster. You can also use the topology to 
quickly identify link information between switches.
• Monitor real-time status of a switch or multiple switches from the LEDs on 
the front-panel images. The system, redundant power system (RPS), and port 
LED colors on the images are similar to those used on the physical LEDs 
themselves.

Switches.”
