Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide

Chapter 1 Overview

Features

VLAN Support

• Depending on the switch model, up to 64 or 250 port-based VLANs are supported for assigning users to VLANs

associated with appropriate network resources, traffic patterns, and bandwidth

Note For information about the maximum number of VLANs supported on each Catalyst 2900 XL and Catalyst 3500 XL

switch, see the Table 8-1 on page 8-2.

• Inter-Switch Link (ISL) and IEEE 802.1Q trunking encapsulation on all ports for network moves, adds, and changes;

management and control of broadcast and multicast traffic; and network security by establishing VLAN groups for

high-security users and network resources

• VLAN Membership Policy Server (VMPS) for dynamic VLAN membership

• VLAN Trunking Protocol (VTP) pruning for reducing network traffic by restricting flooded traffic to links destined for

stations receiving the traffic

Quality of Service and Class of Service

• IEEE 802.1p class of service (CoS) with two priority queues on the 10/100 switch ports and eight priority queues on the

Gigabit ports for prioritizing mission-critical and time-sensitive traffic from data, voice, and telephony applications

• Voice VLAN (VVID) for creating subnets for voice traffic from Cisco IP Phones

Security

• Password-protected access (read-only and read-write access) to management interfaces (CMS and 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

• MAC-based port security for restricting the use of a switch port to a specific group of source addresses and preventing

switch access from unauthorized stations

• Terminal Access Controller Access Control System Plus (TACACS+), a proprietary feature for managing network

security through a TACACS server

Monitoring

• Switch LEDs that provide visual management of port- and switch-level status

• MAC address notification for tracking the MAC addresses that the switch has learned or removed

• Switch Port Analyzer (SPAN) for complete traffic monitoring on any port

• Four groups (history, statistics, alarm, and events) of embedded remote monitoring (RMON) agents for network

monitoring and traffic analysis

• Syslog facility for logging system messages about authentication or authorization errors, resource issues, and time-out

events

Catalyst 3524-PWR XL Switch-Specific Support

• Ability to provide inline power to Cisco IP Phones from all 24 10/100 Ethernet ports

• Autodetection and control of inline phone power on a per-port basis on all 10/100 ports

• Fan-fault and over-temperature detection through Visual Switch Manager (VSM)
