1 1. Introduction The Cabletron Systems SmartStack SSIM-H2-02 2-port Translational Switch SSIM (SmartStack SSIM-H2-02) provides connectivity to 10/100 Mbps Fast Ethernet for the SmartStack STS16-20RM Token Ring Switch. Designed for high performance and low latency, the SmartStack SSIM-H2-02 seamlessly integrates legacy Token Ring networks and Fast Ethernet backbones. ➽ Note: References to SmartStack STS16-20RM are also applicable to SmartStack STS16-20FRM.
2 The module supports translational switching for all key network protocols (such as IP, IPX, SNA, NetBios) and generic conversion: Feature Description SRT and SRB Support for SRT and SRB bridging. IEEE 802.1Q This standard frame-tagging protocol is used to carry frames that belong to different VLANs over the same physical Fast Ethernet link. Benefit: Enables VLAN trunking with other standards based equipment. IEEE 802.1D IEEE 802.
3 Feature Description SNMP SNMP is supported via the host processor (the processor on the SmartStack STS16-20RM). This makes it possible to configure the device in a standards-based way and as an integrated part of the LAN switch. Can serve multiple switches in one stack The SmartStack SSIM-H2-02 can serve as uplink for multiple LAN switches interconnected by a stacker. This reduces the cost of connecting a number of LAN switches to an Fast Ethernet backbone.

5 2. Installation This chapter describes how to install, connect, and start using the SSIM-H2-02. The following main topics are covered: • • • • • • • • Package Contents Installation Procedure Hardware Installation Software Installation Cabling LEDs Power-On Self Test Configuration Package Contents Your SSIM-H2-02 package contains the following items: • • One SmartStack SSIM-H2-02 2-Port Translational Switch SSIM (UTP).
6 Installation Procedure The SSIM-H2-02 is packaged with the software for both the module itself and the SmartStack STS16-20RM Token Ring Switch. The switch is also supplied with both software images. To ensure compatibility between the module and the switch, the latest of the two software revisions should be installed. The switch and SSIM-H2-02 software is also available via Cabletron Systems's online services, including the Cabletron Systems Web site. Install the module as follows: 1.
7 Hardware Installation ➽ Warning: Expansion modules are not hot-swappable. If you install or remove expansion modules while the power to the switch is on, damage may occur to the switch and to the module. ➽ Warning: Be sure to install a version of the base switch software that supports the SSIM-H2-02 (version 3.10 or later) before physically inserting the module. Otherwise, the switch will not recognize it and this may in some cases corrupt the configuration.
8 4. Carefully insert the module into the rails on each side of the expansion slot, sliding it back until the connector on the module is seated into the connector at the back of the slot. See Figure 3. When the module is fully seated, the module faceplate will be flush with the front of the base switch. Figure 3. Installing the SSIM-H2-02 5. Secure the module with the two attached thumb screws. 6. Re-apply power to the switch.
9 The console will display the download activity while the software is transferred over the network by counting received blocks. When the software has been transferred, you will see the following messages: Network download complete. Now transferring to TS Module(s), please wait... Download of TS firmware complete - TS module(s) being reinitialized... ➽ Warning: If you use Telnet as a manager console, download activity will not be displayed.
10 Cabling The module uses standard or crossed-over UTP-5 copper cables. The maximum cable length is 100 m (328 feet). 1. Insert the modular RJ-45 jack from either end of a standard or crossed-over UTP-5 cable into one of the connectors on the SSIM-H2-02 front panel. 2.
11 100 (green) LINK (green) Middle Bottom On The port is in 100 Mbps mode. Off The port is in 10 Mbps mode. On The port is active. Off The port is disabled or not inserted. Table 3. LEDs at the Right of Every Port Power-On Self Test When you start the switch, it will run a power-on self-test to ensure that all the devices are working correctly. During this test, the switch will detect and start any module found in an expansion slot. The module will then perform an internal power-on self test.
12 Configuration The SSIM-H2-02 can be configured in two ways: • From the switch console, directly with a VT100 terminal emulator on the RS232 port or via Telnet. • By a SNMP based graphical management application. Console configuration is described in chapter 3, “Configuration”. The management application is described in the online help. All configuration parameters are stored by the switch and not in the module. This means that the modules can be exchanged without reconfiguring the switch.
13 3. Configuration This chapter explains how to view and edit the configuration of the SSIM-H2-02 using a VT100 terminal emulator attached directly to the SmartStack STS16-20RM Token Ring switch. The SSIM-H2-02 configuration can also be modified from a remote VT100 console via a Telnet session. (The manual supplied with the SmartStack STS16-20RM Token Ring Switch describes how to connect a network management console).
14 Introduction Each SSIM-H2-02 has two 100 Mbps Fast Ethernet ports. In the console configuration, port numbers are used to refer to ports, with ordinary Token Ring ports numbered 1 to 20. If a module is inserted into the left expansion slot, the TS ports are numbered 21 and 22. If a module is inserted into the right expansion slot, the TS ports are numbered 25 and 26. The number of modules in a stack is limited only by the number of available slots in the stack.
15 TS Virtual Ports and VLAN Tagging Unlike ordinary Token Ring ports, Translational Switch (TS) ports can function as trunk ports, which means they can carry traffic belonging to all of the 63 VLANs it is possible to configure in the switch over the same physical cable connection. Frames from different VLANs are distinguished by means of standard IEEE 802.1Q frame tags. A frame tag consists of a 2-byte Ethernet Frame Type of value 0x8100 (as described by standard P802.
16 Bridging Modes Source Routed Switching (SRS) Operation Mode SRS is the default mode of operation. This mode is also restored after NVRAM reset of the SmartStack STS16-20RM switch. In this mode, all ports of the switch are in the same CRF (including SmartStack SSIM-H2-02 switch ports). Frames are switched between ports based only on MAC addresses. In this mode, by default the spanning tree algorithm is disabled.
17 Source Routed Bridging (SRB) Mode ➽ Note: SRT is the suggested mode of operation. If multiple CRFs are used on a switch, all translational links to the same Ethernet cloud should be grouped into one CRF. If a CRF is created in SRB Bridging mode and spanning tree is to be used, IEEE STP must be manually configured on the BRF and CRF. Note that this translational CRF is used only on the Token Ring side and is used to route source-routed Token Ring frames toward the Ethernet cloud. Figure 5.
18 Redundant Connections to Fast Ethernet Network A connection to the Ethernet cloud can be made using several translational links from multiple switches. Translational links connected from one switch to the same Ethernet cloud should be grouped into one common CRF with an assigned LAN segment number. From each switch, one CRF can be connected to the same Ethernet cloud.
19 In a pure Token Ring network, an All Routes Explorer (ARE) frame generated from Station A traverses all rings only one time based on a Routing Information Field (RIF) expanded by each source-routed bridge. In this example, both translational links are in the forwarding state. An ARE frame originating in Ring1 may go through the Ethernet cloud and come back to Ring2.
20 This loop can be resolved by making sure that only one translational link is in the forwarding state or by using the same LAN segment number for all translational links. Using two different LAN segment numbers has some interesting advantages. If the Ethernet cloud becomes physically separated into two parts (see below), both parts can still communicate via the Token Ring cloud.
21 For each CRF of translational links connected to the same Ethernet cloud, a connection attribute can be assigned: — Primary connection – for a main connection to the Ethernet cloud (default value for each CRF). This connection is always forwarding if active. — Secondary 1 – for a backup connection to the Ethernet cloud. This connection is always blocking if the Primary is active. — Secondary 2 – for a second backup connection to the Ethernet cloud.
22 Figure 10 illustrates a network with two physically disjoint Ethernet clouds. Each SmartStack STS16-20RM switch in the configuration has one primary connection to one of the two Ethernet clouds and one secondary connection to the other cloud. This way redundancy for both Ethernet clouds is provided, while at the same time the traffic load between the Token Ring and Ethernet clouds is split between the two switches. Figure 10.
23 Technical Background For each CRF with a translational link, spanning tree should be enabled. For SRT CRF, the default STP algorithm is IEEE 802.1D. Only this spanning tree algorithm can be used for translational links. A translational link has its own LAN segment number and recognizes source routing. However, the translational link is an element of a transparent network and frames are passed through only in the forwarding state.
24 Figure 11. STP Cost Modification In Figure 11, TR Switch 2 and Ethernet Switch 2 know that the cost of the Secondary link is 20,000 higher than the cost of the primary link seen by TR Switch 1 and Ethernet Switch 1. This means that the secondary link will be blocked on one of its ends. To manually configure spanning-tree costs for a backup connection to the Ethernet, set each connection attribute to Primary and then change the spanning-tree costs must be changed on each side of the backup link.
25 General Guidelines This section describes guidelines for work within the console menus. • • To select a menu item, use the arrow keys to highlight it, then press ENTER. If you need to specify additional information for any item (for example, selecting Yes or No or supplying a value), a prompt appears on the screen. If you want to exit the prompt without changing the value, press ESC. • • In most cases, new values are saved when you select Return.
26 Navigating Within the Menus Use the arrow keys (cursor keys) to highlight a selection. If the selection is a menu, pressing the ENTER key displays a new screen of information; if the selection is a command, such as Reset, pressing the ENTER key initiates that function. A heading with an ellipsis (three dots) after it means that when that heading is selected, a submenu or screen is displayed. Unless specified differently, all the screens or menus are accessed in the same way.
27 Configuration Overview Execute the following general steps to configure a SSIM-H2-02: • • • • Determine which VLANs the TS ports should connect. • Assign CRFs to the TS port, thereby creating one virtual port in each VLAN. Optional: create new CRFs to make sure that the CRFs do not have conflicting ring numbers, as discussed in the “Ring Number Restriction” on page 15. • Configure the virtual ports, in particular the tagging mode.
28 VLAN Configuration For general information about the configuration of VLANs, refer to the SmartStack STS16-20RM/STS16-20FRM Token Ring Switch Installation and User Guide. Only issues relating to the configuration of TS ports are described here. BRF Configuration Additional parameter 802.1Q VLAN ID has been added to the BRF configuration: The 802.1Q VLAN ID is the value that is inserted in the IEEE 802.1Q frame tags. It is entered as a decimal value between 1 and 4094. The 802.
29 Status Display only. Shows the current status of the port. Value Meaning Down The port is down. Going Up The port is enabled a protocol connection is being autonegotiated. Up The port is up. Table 4. Translational Switch Physical Port Status Address Demand Aging Level Sets the threshold on the number of entries in the address table on which entries are aged faster. Possible values are 50, 60, 70, 80, and 90 percent and Disabled.
30 Status Display only. Shows the current status of the virtual port. Value Meaning Admin down The port or virtual port is disabled. Waiting for port up The virtual port is waiting for the port to come up. Up The virtual port is up but not forwarding. Forwarding The virtual port is up and forwarding. Temporary down The virtual port is currently down, because the port is temporarily down. Table 5. Translational Switch Virtual Port Status MTU You can use only one value as MTU.
31 VLAN Tagging Mode Sets the VLAN tagging mode of the virtual port; possible values are Tagged and Untagged. As explained previously, only one virtual port on each TS port can be untagged. All other virtual ports must be tagged and the 802.1Q VLAN ID must be the same in both ends. Because VLAN tagging mode imposes a small overhead, the VLAN that is expected to have the largest amount of traffic should be untagged. Default: Untagged for the first virtual port and Tagged for the subsequent ports.
32 Explorer RIF Aging Time On output, the Translational Switch UEM quickly deletes addresses known only from forwarded explorer frames. The session starts with an explorer frame followed by a specifically routed frame. The explorer frame’s RIF aging time makes it possible to limit the number of known address and RIF entries to established sessions. Possible values are 0 to 900 seconds. A RIF with an address is removed after this time if a specifically routed frame does not follow the explorer.
