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.
Note See the “Advantages of Using CMS and Clustering Switches” sectiononpage1-7. Refer to the release notes for the
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
between switches, routers, and servers
• Support for mini-jumbo frames. The Catalyst 2950 switches running Cisco IOS Release12.1(6)EA2 or later support frame
sizes 1500 to 1530 bytes
• Per-port broadcast storm control for preventing faulty end stations from degrading overall system performance with
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
streams from subscriber VLANs for bandwidth and security reasons
• Protected port (private VLAN edge port) option for restricting the forwarding of traffic to designated ports on the same
switch
• Dynamic address learning for enhanced security
