Cisco Systems 3512 XL, 3524 XL Integrated Cisco IOS Switching Solution, Superior Manageability

Integrated Cisco IOS Switching Solution

•Cisco Group Management Protocol (CGMP) enables a switch to selectively and dynamically forward routed IP multicast traffic to targeted multimedia end stations, reducing overall network traffic

•CGMP Fast Leave allows end stations to quickly exit from a multicast session, reducing superfluous network traffic

•Virtual LAN trunks can be created from any port using either standards-based 802.1Q tagging or the Cisco ISL VLAN architecture

•IEEE 802.1p Layer 2 prioritization protocol ready, allowing users to assign data packets to prioritized forwarding queues

•Cisco Virtual Trunking Protocol (VTP) supports dynamic VLANs and trunk configuration across all switches

•Per-port broadcast storm control prevents faulty end stations from degrading overall system performance with broadcast storms

•Command-line interface (CLI) support provides common user interface and command set across all Catalyst series switches and Cisco routers

Superior Manageability

•Built-in Web-based Cisco Visual Switch Manager (CVSM) provides easy-to-use Web-based management interface through a standard browser such as Netscape Navigator or Microsoft Explorer

•Simple Network Management Protocol (SNMP) and Telnet interface support deliver comprehensive in-band management, and a CLI-based management console provides detailed out-of-band management

•Manageable through CiscoWorks 2000 network management software on a per-port and per-switch basis, providing a common management interface for Cisco routers, switches, and hubs

•Cisco Discovery Protocol (CDP) enables a CiscoWorks network management station to automatically discover a switch in a network topology

•Embedded Remote Monitoring (RMON) software agent supports four RMON groups (history, statistics, alarms, and events) for enhanced traffic management, monitoring, and analysis

•Support for all nine RMON groups through use of a switch port analyzer (SPAN) port, which permits traffic monitoring of a single port, a group of ports, or the entire switch from a single network analyzer or RMON probe

•Domain Name Services (DNS) client support provides IP address resolution with user-defined device names

•Trivial File Transfer Protocol (TFTP) reduces the cost of administering software upgrades by downloading from a centralized location

•Network Time Protocol (NTP) provides an accurate and consistent timestamp to all switches within the intranet

•Multifunction LEDs per port for port status, half-duplex/full-duplex, and 10BaseT/100BaseTX indication, as well as switch-level status LEDs for system, RPS, and bandwidth utilization provide a comprehensive and convenient visual management system

Security and Redundancy

•Cisco Uplink Fast technology ensures quick failover recovery, enhancing overall network stability and reliability (Enterprise Edition only)

•Support for TACACS+ authentication enables centralized control of the switch and restricts unauthorized users from altering the configuration (Enterprise Edition only)

•MAC-based port level security prevents unauthorized stations from accessing the switch

•User-selectable address learning mode simplifies configuration and enhances security

•Multilevel security on console access prevents unauthorized users from altering the switch configuration

•IEEE 802.1D Spanning-Tree Protocol support for redundant backbone connections and loop-free networks simplifies network configuration and improves fault tolerance

•Support for redundant loopback connection through secondary GigaStack GBICs in top and bottom switches in a stack

•Support for optional Cisco 600-watt redundant AC power system provides a backup power source for up to four units for improved fault tolerance and network uptime
