CHAPTER 1: INTRODUCTION 1.6 ETHERNET BRIDGING Bridging Overview Ethernet bridges read in packets and make decisions to filter or forward based on the destination address of the packet. The simple filter/forward decision process allows a bridge to segment traffic between two networks, keeping local traffic local. This process increases the availability of each network while still allowing traffic destined for the opposite side of the bridge to pass. A bridge connects two networks together

ETHERNET BRIDGING As with repeaters, IEEE recommends a maximum number of bridges that can be in a signal path. With repeaters we are able to have a signal path of 4 repeaters, 5 segments. With bridges we can have a signal path of 7 bridges, 8 networks. The bridge count includes both local and remote bridges. Spanning Tree Algorithm Since bridges play a very important role in the transfer of data from one network to another, a helpful feature would be the ability to set up a redunda

CHAPTER 1: INTRODUCTION If Bridge 2 fails to receive the Bridge 1 BPDUs during the period defined by "Hello Time", Bridge 2 will initiate a re-span by transmitting a topology change BPDU and eventually come on line to carry the network load. Bridges using STA can be utilized to create very fault tolerant networks. This section has presented only basic information about bridges and Spanning Tree Algorithm. For additional information, refer to the IEEE 802.1d draft specifi

CHAPTER 2 INSTALLATION This chapter contains instructions for installing your BRIM-E6 into a Media Interface Module (MIM) or stand-alone product. It also explains how to install an EPIM into the BRIM-E6. Caution: Observe all static precautions while handling MIMs and EPIMs. 2.1 UNPACKING THE BRIM Unpack the BRIM as follows: 1) Remove the shipping box material covering the BRIM. 2) Carefully remove the module from the shipping box. Leave the module in its non-conductive bag until yo

CHAPTER 2: INSTALLATION 2.2.1 Installing a BRIM-E6 in a MIM To install a BRIM-E6 in a MIM that supports BRIM technology (e.g., EMM-E6 or ESXMIM): Note: We recommend that you power-down your hub even though Cabletron MIMs have “hot swap” capabilities. 1. Power-down your MMAC hub. 2. Disconnect all cables from the MIM. Note the ports to which these cables attach. 3. Unscrew the top and bottom knurled knobs of the MIM face plate. 4. Slide out the MIM, and place it on its side with the

INSTALLING BRIMs 6. Place your BRIM behind the MIM face plate. (See Figure 2-2.) Figure 2-2. Installing the BRIM 7. Insert the connector pins of the BRIM-E6 into the mother board connector on the MIM. 8. Press down firmly on the back of the BRIM until the pins slide all the way into the connector holes. Note: The BRIM-E6 connector must fit securely on the mother board connector. 9. Reinstall the faceplate mounting screws, and install the support post screws. Note: Faceplate and su

CHAPTER 2: INSTALLATION 2.2.2 Installing a BRIM in a Hub To install a BRIM-E6 into a stand-alone hub that supports BRIM technology (e.g., MicroMMAC or NBR-620): 1. Power-down your hub. 2. Disconnect all cables from the hub. Note the ports to which these cables attach. 3. Remove the hub chassis cover. Note: Refer to your specific hub documentation for instructions on removing the hub chassis cover. 4. Remove the BRIM coverplate screws and the BRIM coverplate. (See Figure 2-1.)
