1 Introduction This chapter introduces the 2H253-25R 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 2H253-25R, some features described in this document may not be supported. Refer to the Release Notes shipped with the 2H253-25R to determine which features are supported. 1.
Overview The 2H253-25R is used to connect individual high-bandwidth user devices, such as workstations, or to provide a central switching point for multiple 10/100 Mbps Fast Ethernet segments. The optional HSIMs provide high speed uplinks to networking technologies such as Fast Ethernet, Gigabit Ethernet, Fiber Distributed Data Interface (FDDI), Wide Area Network (WAN), and Asynchronous Transfer Mode (ATM). Some HSIMs can provide additional Fast Ethernet ports in varying media types.
Overview When Auto-Negotiation is supported at both ends of a link, the two devices dynamically adjust to full or half duplex operation based on the maximum capability that can be reached between the two devices. If the device connected to the 2H253-25R cannot auto-negotiate, the 2H253-25R operates according to the capabilities of the other device. 1.1.
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 Rate Limiting The Rate Limiting feature enables the SmartSwitch device to control traffic rates on a per-port, per-priority basis. The network administrator can configure a rate limit (from 100 kbps to 1 Gbs) 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 2H253-25R are listed in the Release Notes shipped with the device. 1.1.16 Standards Compatibility The 2H253-25R is fully compliant with the IEEE 802.3, 802.3u, 802.3x, 802.1D, and 802.1Q standards.
