1 Introduction This chapter introduces the 2E253-49R SmartSwitch 2200 device and provides information about how to obtain additional support from Cabletron Systems. Important Notice Depending on the firmware version used in the 2E253-49R, some features described in this document may not be supported. Refer to the Release Notes shipped with the 2E253-49R to determine which features are supported. 1.
Overview The 2E253-49R is a 48-port high-speed network switching device that supports traditional switching (bridging) and Cabletron Systems SecureFast Switching Virtual Network technology. The optional HSIMs provide one or more additional ports for high speed uplinks to networking technologies such as Fast Ethernet, Gigabit Ethernet, Fiber Distributed Data Interface (FDDI), Wide Area Networks (WANs), and Asynchronous Transfer Mode (ATM).
Overview 1.1.3 Standard/Full Duplex Auto-Negotiation Ports 1 through 48 on the 2E253-49R have the ability to auto-negotiate the port mode of operation (standard [half duplex] or full duplex) between two devices according to the 802.3x standard. Full duplex mode is the default mode of operation for each port. During Auto-Negotiation, two devices automatically exchange information “telling” each other their current operating mode.
Overview SmartTrunk, also referred to as SmartTrunking, is Cabletron Systems’ terminology for load balancing or load sharing. SmartTrunk provides the ability to take full advantage of the network’s redundant bandwidth. SmartTrunk divides network traffic across multiple ports in parallel to provide additional throughput. The SmartTrunk application can be used with any of Cabletron Systems’ switch modules (except ATM modules).
Overview 1.1.9 Traffic Rate Limiting The Rate Limiting feature enables the SmartSwitch device to have control over traffic rates on a per-port, per-priority basis. The network administrator can configure a rate limit (from 100 kbps to 1 Gbps) for a given port with an associated list of IEEE 802.1p priorities (which can include one, some, or all of the eight priority levels defined in 802.1p). Each rate limit is specified as an inbound or an outbound limit.
Overview 1.1.11 GARP Switch Operation Some or all ports on the switch may be activated to operate under the Generic Attribute Registration Protocol (GARP) applications, GARP VLAN Registration Protocol (GVRP) and/or GARP Multicast Registration Protocol (GMRP). GARP is a protocol, or set of rules, that outlines a mechanism for propagating the port state and/or user information throughout a bridged LAN to keep track of users and VLANs on the network fabric.
Overview 1.1.15 Optional HSIMs and VHSIMs Optional HSIMs and VHSIMs are available from Cabletron Systems for additional connectivity to various networking technologies. The HSIMs and VHSIMs available for the 2E253-49R are listed in the Release Notes shipped with the device. 1.1.16 Standards Compatibility The 2E253-49R is fully compliant with the IEEE 802.3, 802.3u, 802.3x, 802.1D, and 802.1Q standards.
