4 Cisco Product Catalog, June, 2002

• Switch Database Manager templates for access, routing, and VLAN deployment scenarios allow the network

administrator to easily maximize memory allocation to the desired features based on deployment-speciﬁc requirements.

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

architecture.

• Support for up to 1,005 VLANs per switch and up to 128 instances of spanning tree per switch.

• Cisco Group Management Protocol (CGMP) server functionality enables a switch to serve as the CGMP router for CGMP

client switches-requires Enhanced Multilayer Software Image (EMI).

• IGMP snooping provides for fast client joins and leaves of multicast streams and limits bandwidth-intensive video trafﬁc

to only the requestors.

• 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) provide 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 Timing 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, 10BaseT/100BaseTX /1000BaseT indication, as

well as switch-level status LEDs for system, redundant power supply, and bandwidth utilization provide a comprehensive

and convenient visual management system.

High-Performance IP Routing

All IP routing features require the Enhanced Multilayer Software Image (EMI)

• Cisco Express Forwarding (CEF)-based routing architecture performed in hardware to deliver extremely high-

performance IP routing.

• Support for all commonly deployed and industry standard IP unicast routing protocols (RIPv1, RIPv2, OSPF, IGRP,

EIGRP) for load balancing and constructing scalable LANs.

• Static IP routing for manually building a routing table of network path information.

• Inter-VLAN IP routing for full Layer 3 routing between two or more VLANs.

• Equal cost routing for load balancing and redundancy.

• Protocol-Independent Multicast (PIM) for IP multicast routing within a network that enables the network to receive the

multicast feed requested and for switches not participating in the multicast to be pruned - support for PIM sparse mode

(PIM-SM), PIM dense mode (PIM-DM), and PIM sparse-dense mode.

• Distance Vector Multicast Routing Protocol (DVMRP) tunneling for interconnecting two multicast-enabled networks

across non-multicast networks.

• Fallback bridging for forwarding of non-IP trafﬁc between two or more VLANs.

• Cisco Hot Standby Router Protocol (HSRP) to create redundant fail-safe routing topologies.

Scalability

Ultra-Flexible and Scalable Stacking and Cisco Switch Clustering Technology

• The Cisco GigaStack Gigabit Interface Converter (GBIC) delivers a hardware-based, independent stacking bus with up

to 2 Gbps forwarding rate in a point-to-point conﬁguration, or 1-Gbps forwarding bandwidth when daisy chained with up

to nine switches.
