    Configuration and Switch Management The BayStack 350 switch is shipped directly from the factory ready to operate in any 10BASE-T or 100BASE-TX standard network. You can manage the switch using any generic SNMP-based network management software; however, you must assign an IP address to the switch. You can set the switch’s IP address by using the Console/Comm Port or BootP, which resides on the switch.

    Desktop Switch Application Figure 1-5 shows the BayStack 350-24T switch used as a desktop switch, where desktop workstations are connected directly to switch ports. This configuration provides dedicated 100 Mb/s connections to the network center, to the server, and up to 26 users. This configuration uses the optional 400-4TX MDA (10BASE-T/100BASE-TX MDA).

    Segment Switch Application Figure 1-6 shows the BayStack 350-24T switch used as a segment switch to alleviate user contention for bandwidth and eliminate server and network bottlenecks. Before segmentation, 88 users had a total bandwidth of only 10 Mb/s available. After segmentation, 92 users have 40 Mb/s, four times the previous bandwidth, while adding 22 dedicated 100 Mb/s connections.

BayStack 350 switches allow you to assign ports to VLANs using the console or TELNET; VLAN assignment is not currently available through SNMP. You can assign different ports (and therefore the devices attached to these ports) to different broadcast domains.

  • Page 43: Ieee 802.1Q Tagging

    IEEE 802.1Q Tagging BayStack 350 switches operate in accordance with the IEEE 802.1Q tagging rules. Important terms used with the 802.1Q tagging feature are: • VLAN Identifier (VID) --- the 12-bit portion of the VLAN tag in the frame header that identifies an explicit VLAN.
  • Page 44 • Filtering Database Identifier (FID) --- the specific filtering/forwarding database within the BayStack 350 switch that is assigned to each VLAN. The current version of software assigns all VLANs to the same FID. This is referred to as Shared VLAN Learning in the IEEE 802.1Q specification.

  • Page 67: Multilink Trunks

    (up to 800 Mb/s in full-duplex mode). BayStack 350 switches can be configured with up to six MultiLink trunks. MultiLink Trunking software detects misconfigured (or broken) trunk links and redirects traffic on the misconfigured or broken trunk link to other trunk members within that trunk.

    Before Configuring Trunks When you create and enable a trunk, the trunk members (switch ports) take on certain settings necessary for correct operation of the MultiLink Trunking feature. These settings, along with specific configuration rules, must be considered before configuring your MultiLink trunk.
  • Page 80 • All trunk members must be configured into the same VLAN before the Trunk Configuration screen’s Trunk Status field can be set to Enabled (See “VLAN Configuration” on page 3-22). • When an active port is configured in a trunk, the port becomes a trunk member as soon as the Trunk Status field is set to Enabled.

    The Path Cost for T1 is 4 (Path Cost = 1000/LAN speed, in Mb/s). If a second three port trunk (T2) is configured with an aggregate bandwidth of 210 Mb/s, with a comparable Path Cost of 4, the switch software chooses the trunk with the larger bandwidth (T1) to determine the most efficient path.
  • Page 82 The switch can also detect trunk member ports that are physically misconfigured. For example, in configured correctly to trunk member ports 7, 9, and 11 of switch S2. The Spanning Tree Port Configuration screen for each switch shows the port State field for each port in the Forwarding state.

    Additional Tips About the MultiLink Trunking Feature When you create a MultiLink trunk, the individual trunk members (the specific ports that make up the trunk) are logically connected and react as a single entity. For example, if you change spanning tree parameters for any trunk member, the spanning tree parameters for all trunk members are changed.

  • Page 198: Diagnosing And Correcting The Problem

    Diagnosing and Correcting the Problem Before you perform the problem-solving steps in this section, cycle the power to the BayStack 350 switch (disconnect and then reconnect the AC power cord); then, verify that the switch follows the normal power-up sequence.

  • Page 199: Normal Power-Up Sequence

    Normal Power-Up Sequence In a normal power-up sequence, the LEDs appear as follows: After power is applied to the switch, the Pwr (Power) LED turns on within five seconds. The switch initiates a self-test, during which the port LEDs display various patterns to indicate the progress of the self-test.

  • Page 200: Port Connection Problems

    The BayStack 350 switch negotiates port speeds according to the IEEE 802.3u autonegotiating standard. The switch adjusts (autonegotiates) its port speed and duplex mode to match the best service provided by the connected station, up to 100 Mb/s in full-duplex mode.

  • Page 201: Port Interface

    • If the autonegotiation feature is not present or is not enabled at the connected station, the BayStack 350 switch may not be able to determine the correct duplex mode. In both situations, the BayStack 350 switch “autosenses” the speed of the connected station and, by default, reverts to half-duplex mode.
