Key Features The CenturyStack Dual Speed Managed Hub Series has many advanced features: 10/100Mbps Auto Sensing Ports All ports in the CenturyStack 8100 Series are dual speed auto sensing, including the MDI-II ports. Hubs automatically detect the transmission speed and set the port accordingly. Stackability Every model in the CenturyStack 8100 Series is compatible, and can be configured in the same stack with up to 6 hubs, using cascade cables.
RMON Probe Capability The Remote Network Monitoring (RMON) probe is an instrument that exists for the purpose of managing a network. The goals of the RMON probe are described in the following sections: Offline Operation, Proactive Monitoring, Problem Detection and Reporting, Value Added Data, and Multiple Managers. The CenturyStack 8100 Managed Series Hubs support RMON group (1) statistics, group (2) History, group (3) Alarm, and group (9) Event.
Redundant Link Capacity Redundant links can be configured enabling up to 24 pairs in a CenturyStack. For each pair of redundant links one port must be set as the primary and active, the other as backup and isolated. If the primary port fails, it is isolated and the backup port is set to primary and active. Address Tracking Capability CenturyStack provides MAC Address based tracking capability for traffic analysis to diagnose network problems such as Intrusion.

• Internal Switch (Bridge): The Internal Switch LED is always on when the internal switch (bridge) function is active and forwarding the data. • External Switch (Bridge): The External Switch LED is on when data is being forwarded from one segment to another segment through the external switch port. • Hub ID: Each linked hub is automatically assigned a hub ID number and this number is indicated in the ID indicator.
Mini Console The Mini Console is a high definition display with console keys that enables you to easily monitor and configure the system. The Mini Console provides watch diagnostic functions, including port settings, status monitoring, traffic utilization, collision, and error rate. With the Mini Console, you can configure each device in a CenturyStack hub and all of its ports. For more information see Chapter 3: Managing Through the Mini Console.
Chapter 1 Installation Choosing a Location The CenturyStack location should be less than 100 meters from servers, workstations, or switches. The CenturyStack can be desk mounted or rack mounted. CAUTION: Category 5 UTP/STP cables are environmentally sensitive. Make sure that the cable route is not too close to electrical noise sources such as power lines or fluorescent lights. Stacking The CenturyStack Managed Series are stackable in standard 19” racks. Up to six hubs can be stacked with cascade cables.
Cascading hubs with cascade cables to make a stack is as simple as connecting the Up port of one hub to the Down port of another hub as illustrated below. NMU Stackable Up Down Switch/ Transceiver NMU Stackable Up Down Switch/ Transceiver NMU Stackable Up Down Switch/ Transceiver Cascade Ports NOTE: To connect the cascade cable, the Up port on one hub connects to the Down port of another hub. Constructing a Management Hub Stack A stack can be constructed with up to six hubs in total.
• Console Management Refer to Chapter 4: Console Management • Web-BasedManagement Refer to the CenturyStack Network Management Guide • SNMP Management Refer to the CenturyStack Network Management Guide Slave Hub Role Slave hubs supply the stack with additional ports (12/24) and an additional expansion module slot. Slave hubs can be positioned above or below the master hub. The 8112-01-S and 8124-01-S can also act as stand alone unmanaged hubs.
10Mbps connections. All ports are hot pluggable. It is recommended you label each cable to identify the device or port at each end.
Connecting Fast Ethernet Switching Hubs Connect 100Mbps devices using UTP/STP Cat 5 cables with RJ-45 connectors, maximum length 5 meters, enabling sending/receiving to other fast Ethernet switching hubs. By default, each port is set to auto sensing mode. CenturyStack can detect a connected 100BASE-TX device and transmit/receive information to/from it. The distance between switching hubs can be extended up to 2km by connecting two hubs through expansion modules using fiber cable.
CenturyStack 8100 Managed Hub
Chapter 2 Using Expansion Modules Expansion Module Overview Expansion modules provide additional functions such as internal bridging of 10Mbps and 100Mbps segments and extended distances between devices.
Backpressure (flow control) When packets are passed from 100Mbps segments to 10Mbps segments the flow is restricted due to the lesser capacity of the 10Mbps segment causing backpressure and resulting in dropped packets. With flow control or backpressure enabled, packets are made to wait until the flow is unrestricted before being sent, reducing the number of dropped packets. Installing a Bridge Module Power down CenturyStack before installing a bridge module.
2. Remove the power from the hub by disconnecting the power cable from the AC outlet. 3. Remove the installed bridge module or blank cover of the expansion module slot (not the NMU slot, only the bottom slot is available) by turning the two knobs on the front counterclockwise as shown below. NMU Stackable Up AC LINE 100-240VAC 50-60Hz, 1.5A MAX Down Switch/ Transceiver Removing the Blank Module Panel 4. Insert the new module, ensuring that the edges slide through the guides, as shown below.
10. For a hub stack with a master present, you must configure the software for the installed bridge module to enable the internal bridge function because the software default setting is disabled. The default software setting will not allow the internal bridge function to enable. The software must be configured using a master hub. 11. Start a Console or Web-Based Management session and set the software configuration for the new module.
FX Module LED Indicators The LEDs on each module indicate port activity. All LEDs are green. • Link: On, indicates a link is up. • TX: On, indicates a transmission in progress. • RX: On, indicates receiving data. • FDX: On, indicates the port is set to full duplex. Off, indicates the port is set to half duplex. • Collision:On, indicates collision occurring. 2 3 Ports Switch Module LINK Link up Transmit Receive TX RX FDX COL Full Duplex Collision FX Module LEDs NOTE: Fiber Modules support 100Mbps only.

transmissions. This counter is incremented by one each time that a port automatically isolates as a consequence of false carrier events. The conditions which cause a port to automatically isolate are defined by the transition from the False Carrier state to the Link Unstable state. The port automatically recovers. Symbol Errors (100Mbps only): Total symbol errors for 100Mbps transmissions.
Address Tracking Information The Address Tracking Information Menu provides per port based node tracking capability (MAC address based). This capability provides the basic traffic analysis function to diagnose network problems, such as Intrusion. The node tracking function records the source MAC of each data packet and provides the filters for data analysis. Address Tracking Menu Source Address Changes: This counter is incremented by one for each time that the Last Source Address for this port changes.
Source MAC Address (00-E0-95-00-00-00 for example) in the tracking list contains the value that is given by the Last Source Address for this port. This list can contain 15 entries. The list does not age out, the first entries are deleted to accommodate new entries when the list is full.
Address Search Information Selecting this option presents the Address Search Information Menu as shown below. Address Search Information Menu The CenturyStack provides per segment based source (MAC address) matching capability. The active address tracking capability is used to watch for a given MAC address and report on which port it was seen. This capability can also be used to collect the necessary information for mapping the topology of a network. Up to 8 MAC addresses can be searched simultaneously.
AddressSearchStatus • In Use: A management station has obtained ownership. • Not in Use: No other management station has obtained ownership. A management station first retrieves the values of the appropriate instances of the Address Search Lock and Address Search Status objects, periodically repeating the retrieval if necessary, until the value of Address Search Status is ‘Not In Use’. The management station then tries to set the Address Search Lock In Use.
Broadcast Storm Protection The Hub periodically monitors the broadcast counters of each hub port to detect a broadcast storm condition. If a hub port is detected to be causing a broadcast storm, it is automatically partitioned and a trap is sent to the network manager. The Hub continually monitors those ports that have been partitioned to check if the broadcast storm condition still exists. The partitioned hub port is auto recovered to normal operation once the broadcast storm condition is released.
Optional Module Broadcast Packet Rate Threshold: The number of broadcast packets received on a given optional module per second. The range is 0 to 14,880 packets per second. Port Broadcast Packet Rate Threshold: The number of broadcast packets received on a given port per second. The range is 0 to 14,880 packets per second.
Formula for calculating Broadcast packet rate Broadcast packet rate = Broadcast packet received Sampling Interval in Seconds Broadcast Storm Detected This menu displays a list of ports with a detected Broadcast Storm. Broadcast Storm Detected Menu Each broadcast storm is detected and the hub and port number are listed in this menu. If there have been no storms detected, this menu is empty. A maximum of 32 broadcast storms can be displayed, 16 per page.

Troubleshooting the Network Q: The local-console ‘login screen’ does not come up sometimes when a terminal (PC running terminal emulation) is connected to already booted master hub. Why? A: The screen must be refreshed, when CenturyStack is running and the terminal emulator is started. Pressing Ctrl + R refreshes the screen and the login menu appears. Q: Users of the 100Mbps segment cannot use Web-Based Management, however 10Mbps segment users can.
Q: Is there a loop detection and isolation feature available in CenturyStack, in case two switch modules (internal bridging enabled on the hardware) are installed in the same stack? A: No. The stack will go into a loop even before the software has booted. Therefore, the only control is on hardware (jumpers on the PC board) Q: In Web-Based Management, the Hub’s front panel is not displayed. A: For Netscape users, you need to clear the memory cache.
