Ease of Use and Ease of Deployment
Cluster Management Suite (CMS) software for simplified switch and switch cluster management through a web
•
browser, such as Netscape Communicator or Microsoft Internet Explorer, from anywhere in your intranet
• Switch clustering technology used with CMS for
– Unified configuration, monitoring, authentication, and software upgrade of multiple switches (refer to the release
notes for a list of eligible cluster members).
Automatic discovery of candidate switches and creation of clusters of up to 16 switches that can be managed
–
through a single IP address.
Extended discovery of cluster candidates that are not directly connected to the command switch.
–
Hot Standby Router Protocol (HSRP) for command-switch redundancy. The redundant command switches used for
•
HSRP must have compatible software releases.
See the "Advantages of Using CMS and Clustering Switches" section on page
Note
CMS, cluster hardware, software, and browser requirements.
Performance
Autosensing of speed on the 10/100 ports and autonegotiation of duplex mode on all switch ports for optimizing
•
bandwidth
IEEE 802.3x flow control on Gigabit ports operating in full-duplex mode
•
• Fast EtherChannel and Gigabit EtherChannel for enhanced fault tolerance and for providing up to 2 Gbps of bandwidth

•
broadcast storms
Port Aggregation Protocol (PAgP) for automatic creation of EtherChannel links
•
Internet Group Management Protocol (IGMP) snooping support to limit flooding of IP multicast traffic
•
Multicast VLAN registration (MVR) to continuously send multicast streams in a multicast VLAN, but to isolate the
