Cisco continues its commitment to ease of use with Express Setup, a Web-based setup tool that frees users from using

console cables and the command-line Interface. Cisco switches can now be initially conﬁgured by simply connecting

a PC to a switch and using a standard Internet browser. Auto-MDIX simpliﬁes cable connectivity for the Catalyst

3750 and Catalyst 2970 by allowing either straight or crossover cables to be used interchangeably.

The Catalyst 3750, 3550, 2970, 2955, 2950-EI, and 2950-LRE receive support for the 802.1x Guest VLAN. This

feature enables organizations with 802.1x deployments to allow guests and visitors limited network access without

requiring them to have 802.1x client software.

All platforms now support the complete Cisco Port Security MIB which provides complete SNMP management of

port security. This MIB includes additional functionality over the 12.1(13)EA1 release with support for conﬁguring

secure MAC addresses and receiving SNMP trap notiﬁcations when security violations occur.

The Catalyst 3750, 3550, and 2970 have two additional Port Security Enhancements. The ﬁrst enhancement removes

the limitation on the maximum number of secure MAC addresses allowed. There can now be as many secure MAC

addresses as there are unicast MAC addresses. Secondly, port security can now be applied on trunk ports in addition

to the already supported access ports.

For Metro Ethernet customers, VLAN 1 Minimization increases the robustness of the Cisco VLAN architecture by

allowing larger and more scalable Layer 2 topologies.

For users with multiple multicast sources such as video cameras, the IGMP Snooping Timer can now be adjusted to

optimize the performance of multicast data ﬂows. This feature does not apply to the 3750, 3550, and 2970 as those

platforms' hardware automatically optimize for this situation.

The embedded, Web-based, network management software in the Catalyst 3750, 3550, 2970, 2955, 2950, and

2950-LRE Series, Cisco's Cluster Management Suite (CMS), has enhancements including support for PACL and

Layer 2 Traceroute.

These Cisco IOS Software features are available as a FREE software upgrade to current Catalyst 3750, 3550, 2970,

2955, 2950, and 2950-LRE series switch users.
