Overview of the EtherSpeedII Switch Modules

•20 RJ-45 UTP network interface connectors (EtherSpeedII 10/100BASE-T switch module only)

•16 MT-RJ fiber connectors (EtherSpeedII 100BASE-FX switch module only)

•Front-panel LEDs to indicate port status

•Port-based virtual LANs (VLANs)

•Protocol-based VLANs

Protocol-sensitive VLANs classify packets based on protocol types. Most customers have multiple protocols per LAN segment, so a switch port needs to support multiple VLANs based on different protocol types. This feature allows you to separate data based on protocols and not on physical limitations.

•IEEE 802.1Q tag recognition support

EtherSpeedII switch modules support recognition of VLAN tagged frames based on IEEE 802.1Q tags. Frames entering an EtherSpeedII switch module port that contain an 802.1Q tag are mapped to a corresponding VLAN. Based on the final destination, the frame is sent as either an Ethernet-type frame or an 802.1Q VLAN tagged frame. VLAN membership can be assigned by any combination of port with either tag or protocol.

•Support for IEEE 802.1d Spanning Tree

•Content-addressable memory (CAM) support for 8192 entries

•Port steering/port mirroring

•Input and output filtering supported by switching software

•Hardware support for IP multicast

•Support for RMON Management Information Base (MIB)

—Ethernet Statistics Group

—Ethernet History Group

—Ethernet Alarm Group

—Ethernet Event Group

•Ability to install, remove, and replace a module in an operational chassis (hot-swap)

•Hardware Assist Multi-Protocol Over ATM (MPOA)
