Secure Shell (SSH) Protocol and SNMPv3 protect information from tampering or eavesdropping by encrypting

information being passed along the network, thereby guarding administrative information. These features are

available only on the enhanced image.

With the Cisco Catalyst 2955, network managers can implement high levels of console security. Multilevel access

security on the switch console and the Web-based management interface prevent unauthorized users from accessing

or altering switch conﬁguration. TACACS+ and RADIUS authentication enable centralized access control of the

switch and restrict unauthorized usersfrom altering the conﬁguration.Deploying security can be done through Cisco

Cluster Management Suite (CMS) Software Security Wizards, which ease the deployment of security features that

restrict user access to a server, a portion of the network, or the entire network.

Do Cisco Catalyst 2955 switches support switch clustering?

Yes.Cisco Catalyst 2955 switches can be managed using Cisco CMS Software, which uses Cisco switch clustering

technology. Cisco CMS is Web-based software that is embedded in Cisco Catalyst 3550, 2955, 2950, 2950ST-LRE,

3500 XL, 2900 XL, 2900LRE XL,and 1900 switches. Through Cisco switch clusteringtechnology, userscan access

Cisco CMS with any standard Web browser to manage up to 16 of these switches at once, regardless of their physical

proximity—with the option of using a single IP address if desired.

Cisco CMS provides an integrated management interface for Cisco Catalyst 2955 switches to deliver intelligent

services such as multilayer switching, QoS, multicast, and security access control lists (ACLs). Cisco CMS allows

administrators to take advantage of beneﬁts formerly reserved for only the most advanced networks—without

having to learn the command-line interface (CLI) or even the details of the technology. The new Cisco CMS Guide

Mode leads the user step-by-step through the conﬁguration of high-end features and provides enhanced online help

for context-sensitive assistance. In addition, wizards provide automated switch conﬁguration to optimally support

video streaming or videoconferencing, voice over IP (VoIP), and mission-critical applications. Wizards for LAN

security and multicast are also provided.

Cisco CMS supports standards-based connectivity options such as Ethernet, Fast Ethernet, Fast EtherChannel,

Gigabit Ethernet, and Gigabit EtherChannel connectivity. Because Cisco switch clustering technology is not limited

to a singlestack of switches,Cisco CMS expandsthe traditional cluster domain beyond asingle wiring closet,saving

time and effort for network administrators.

Cisco Catalyst 2955 Series switches can be conﬁgured either as command or member switches in a Cisco switch

cluster. Cisco CMS also allows the network administrator to designate a standby or redundant command switch,

which takes the commander duties if the primary command switch fails. Other key features include the ability to

simultaneously conﬁgure multiple ports and switches, perform software updatesacross the entire clusterat once, and

clone conﬁgurations to other clustered switches for rapid network deployments. Bandwidth graphs and link reports

provide useful diagnostic information, and the topology map gives network administrators a quick view of the

network status.

Does the Cisco Catalyst 2955 Series support Inter-Switch Link (ISL) trunking?

No. The Cisco Catalyst 2955 Series hardware does not support ISL trunking. For customers with a requirement

to deploy ISL trunking, Cisco Catalyst 3550 switches support both ISL and 802.1Q trunks.
