Catalyst 2960 and 2960-S Switch Software Configuration Guide
OL-8603-09
Chapter 1 Overview
Features
• Support for VTP version 3 that includes support for configuring extended range VLANs (VLANs
1006 to 4094) in any VTP mode, enhanced authentication (hidden or secret passwords), propagation
of other databases in addition to VTP, VTP primary and secondary servers, and the option to turn
VTP on or off by port
Security Features
• IP Service Level Agreements (IP SLAs) responder support that allows the switch to be a target
device for IP SLAs active traffic monitoring
Note To use IP SLAs, the switch must be running the LAN Base image.
• Web authentication to allow a supplicant (client) that does not support IEEE 802.1x functionality to
be authenticated using a web browser
Note To use Web Authentication, the switch must be running the LAN Base image.
• Local web authentication banner so that a custom banner or an image file can be displa yed at a web
authentication login screen
• IEEE 802.1x Authentication with ACLs and the RADIUS Filter-Id Attribute
Note To use this feature, the switch must be running the LAN Base image.
• Password-protected access (read-only and read-write access) to management interfaces (device
manager, Network Assistant, and the CLI) for protection against unauthorized configuration
changes
• Multilevel security for a choice of security level, notification, and resulting actions
• Static MAC addressing for ensuring security
• Protected port option for restricting the forwarding of traffic to designated ports o n the same switch
• Port security option for limiting and identifying MAC addresses of the stations allowed to access
the port
• VLAN aware port security option to shut down the VLAN on the port when a violation occurs,
instead of shutting down the entire port.
• Port security aging to set the aging time for secure addresses on a port
• BPDU guard for shutting down a Port Fast-configured port when an invalid configuration occurs
• Standard and extended IP access control lists (ACLs) for defining inbound security policies on
Layer 2 interfaces (port ACLs)
• Extended MAC access control lists for defining security policies in the inbound direction on Layer 2
interfaces
• Source and destination MAC-based ACLs for filtering non-IP traffic
• DHCP snooping to filter untrusted DHCP messages between untrusted hosts and DHCP servers
• IP source guard to restrict traffic on nonrouted interfaces by filtering traffic based on the DHCP
snooping database and IP source bindings
