  • Page 40: Multiple Vlan Considerations, Single Forwarding Database Operation

    Static Virtual LANs (VLANs) Multiple VLAN Considerations Multiple VLAN Considerations Switches use a forwarding database to maintain awareness of which external devices are located on which VLANs. Some switches, such as the switches covered in this guide, have a multiple forwarding database, which means the switch allows multiple database entries of the same MAC address, with each entry showing the (different) source VLAN and source port.

    Static Virtual LANs (VLANs) Multiple VLAN Considerations drops the packet. This is not a problem for a switch with a multiple forwarding database because the switch allows multiple instances of a given MAC address; one for each valid destination. However, a switch with a single forwarding database allows only one instance of a given MAC address.

    Multiple Instance Spanning-Tree Operation Overview Multiple-Instance spanning tree operation (802.1s) ensures that only one active path exists between any two nodes in a spanning-tree instance. A spanning-tree instance comprises a unique set of VLANs, and belongs to a specific spanning-tree region. A region can comprise multiple spanning-tree instances (each with a different set of VLANs), and allows one active path among regions in a network.

Thus, these protocols map one loop-free, logical topology on a given physical topology.

    Multiple Instance Spanning-Tree Operation 802.1s Multiple Spanning Tree Protocol (MSTP) In a mesh environment, the default MSTP timer settings (Hello Time and Forward Delay) are usually adequate for MSTP operation. Because a packet crossing a mesh may traverse several links within the mesh, using smaller- than-default settings for the MSTP Hello Time and Forward Delay timers can cause unnecessary topology changes and end-node connectivity problems.

  • Page 108: How Mstp Operates, Mst Regions

    Multiple Instance Spanning-Tree Operation 802.1s Multiple Spanning Tree Protocol (MSTP) MSTI must initially exist in the IST instance of the same MST region. When you assign a static VLAN to an MSTI, the switch removes the VLAN from the IST instance. (Thus, you can assign a VLAN to only one MSTI in a given region.) All VLANs in an MSTI operate as part of the same single spanning tree topology.

  • Page 109

    Multiple Instance Spanning-Tree Operation 802.1s Multiple Spanning Tree Protocol (MSTP) Between regions there is a single, active spanning-tree topology. How Separate Instances Affect MSTP Operation. Assigning different groups of VLANs to different instances ensures that those VLAN groups use independent forwarding paths. For example, in figure 4-3 each instance has a different forwarding path.

  • Page 110: Common Spanning Tree (cst)

    Multiple Instance Spanning-Tree Operation 802.1s Multiple Spanning Tree Protocol (MSTP) Within a region, traffic routed between VLANs in separate instances can take only one physical path. To ensure that traffic in all VLANs within a region can travel between regions, all of the boundary ports for each region should belong to all VLANs configured in the region.

This means that if redundant physical links exist in separate VLANs within the same instance, MSTP blocks all but one of those links.

    Multiple Instance Spanning-Tree Operation 802.1s Multiple Spanning Tree Protocol (MSTP) Terminology BPDU — Acronym for bridge protocol data unit. BPDUs are data messages that are exchanged between the switches within an extended LAN that use a spanning tree protocol topology. BPDU packets contain information on ports, addresses, priorities and costs and ensure that the data ends up where it was intended to go.

  • Page 113

    Multiple Instance Spanning-Tree Operation 802.1s Multiple Spanning Tree Protocol (MSTP) MSTP BPDU (MSTP Bridge Protocol Data Unit): These BPDUs carry region-specific information, such as the region identifier (region name and revision number). If a switch receives an MSTP BPDU with a region identifier that differs from its own, then the port on which that BPDU was received is on the boundary of the region in which the switch resides.

    Multiple Instance Spanning-Tree Operation 802.1s Multiple Spanning Tree Protocol (MSTP) If a port on a switch configured for MSTP receives a legacy (STP/802.1D ■ or RSTP/802.1w) BPDU, it automatically operates as a legacy port. In this case, the MSTP switch interoperates with the connected STP or RSTP switch as a separate MST region.

    Quality of Service (QoS): Managing Bandwidth More Effectively Introduction QoS is implemented in the form of rules or policies that are configured on the switch. While you can use QoS to prioritize only the outbound traffic while it is moving through the switch, you derive the maximum benefit by using QoS in an 802.1Q VLAN environment (with 802.1p priority tags) or in an untagged VLAN environment (with DSCP policies) where QoS can set priorities that downstream devices can support without re-classifying the traffic.

    Quality of Service (QoS): Managing Bandwidth More Effectively Introduction Terminology Term Use in This Document 802.1p priority A traffic priority setting carried by a VLAN-tagged packet moving from one device to another through ports that are tagged members of the VLAN to which the packet belongs. This setting can be from 0 - 7.

    Quality of Service (QoS): Managing Bandwidth More Effectively Introduction Term Use in This Document outbound port For any port, a buffer that holds outbound traffic until it can leave the switch through that port. By queue default, there are eight outbound queues for each port in the switch. Queue 8 is the highest priority queue;...

    Quality of Service (QoS): Managing Bandwidth More Effectively Introduction A QoS configuration enables you to set the outbound priority queue to which a packet is sent. (In an 802.1Q VLAN environment with VLAN- tagged ports, if QoS is not configured on the switch, but is configured on an upstream device, the priorities carried in the packets determine the forwarding queues in the switch.) ■...

    Quality of Service (QoS): Managing Bandwidth More Effectively Introduction You can configure a QoS priority of 0 through 3 for an outbound packet. When the packet is then sent to a port, the QoS priority determines which outbound queue the packet uses: Table 5-2.
