Page 16: Topology
closet must be Category 5 certified. Where these blocks do not meet the standard, an upgrade is necessary. Topology A Fast Ethernet workgroup is configured in a star topology and is built around a maximum of two repeaters. Each workgroup forms a separate LAN (also known as a segment or collision domain), and these workgroups can be easily interconnected through switches, bridges, or routers to form one LAN large enough to encompass a high-rise building or campus environment. -
Page 17: Hubs
The maximum length of a twisted-pair segment (that is, distance between a port in the hub to a single-address network device such as a PC, server, or LAN switch) is 100 meters. The maximum diameter in a collision domain is about 205 meters using two Class II hubs and 200 meters using one Class I hub. -

Page 51: Controlling Individual Ports
Controlling Individual Ports The Port Configuration Menu, accessible from the Network Monitoring menu, allows you to view the status of individual ports and to control their settings. The available settings are: Port Determines which port is displayed. Port State This toggle determines whether the port should be enabled or disabled (manually partitioned). -
Page 52: Forwarding Configuration
You can also enter the port’s Port ID number. Forwarding Configuration The switch monitors all of the Ethernet segments to which it is connected. Since Ethernet frames include the MAC (Ethernet) address of the originating station, the switch can automatically learn what segment the frame’s destination is connected to, and forward the frame to only that segment. - Page 53 1 of this switch; the value “0” would represent that the station can not be connected to any port of the switch, and the switch will filter out all packets from the station.
-
Page 54: Spanning Tree Protocol And Configuration
6. Choose SAVE to add the entry to the forwarding table. Spanning Tree Protocol and Configuration The DES-2212 implements the IEEE 803.1d Spanning Tree Protocol (STP) to provide the following functions: Network loop detection and prevention. There should only be one path between any two stations on the network. -
Page 55: Introduction To Spanning Tree Protocol Parameters
Introduction to Spanning Tree Protocol Parameters The Spanning Tree Protocol works on two levels: the bridge (i.e., switch) and port levels. At the bridge level, the STP algorithm calculates a bridge identifier for each bridge and then determines the root bridge and the designated bridges. - Page 56 100, while a 100 Mbps port has a path cost of 10. In the following figure, three DES-2212 switches are used to bridge three LANs together. Switch 3 is selected as the root bridge because it has the lowest bridge ID.
-
Page 57: Setting Spanning Tree Protocol Parameters
2. Choose Protocol Parameters from the Spanning Tree Algorithm Parameters menu. 3. The Protocol Parameters menu displays the current status of the Spanning Tree Algorithm’s operation on the DES-2212, and allows you to change several of the bridge parameters. All of these settings are described below. - Page 58 STA root. Root Cost Displays the cost for the path between this switch and the root bridge. If the DES-2212 is the root bridge, then this field displays zero. Root Port Identifies the port (on this bridge) that offers the least path cost from this bridge to the root bridge.
- Page 59 DES-2212 still has not received a BPDU from the root bridge, it will start sending its own BPDU to all other bridges for permission to become the root bridge. If it turns out that the DES-2212 has the lowest bridge identifier, it will then become the root bridge. Bridge Max Age ranges from 6 to 40 seconds, with 20 seconds as the default value.
- Page 60 In STP, only root and designated ports are used. Designated Root Indicates the MAC (Ethernet) address of the switch/bridge that is the STP designated root for the network. Designated Cost Displays the path cost from this port to the designated root.
-
Page 61: Monitoring The Switch
ID used for selecting the root port. The lower the port ID, the more likely the port is to become the root port. Monitoring the Switch The switch supports several monitoring functions, allowing you to keep statistics on the operation of each port. Displaying Port Statistics The switch collects Ethernet transmission statistics for each individual port. - Page 62 Fragments Counts packets less than 64 bytes with either bad framing or an invalid CRC. These are normally the result of collisions. Jabber Frames Counts frames with length more than 1518 bytes and with CRC error or misaligned (bad framing). Collision Counts collisions on the Ethernet segment.
