    In normal usage (and typical implementations) there is no need to modify any of these parameters. The default values will result in the maximum number of aggregations possible. If the switch is placed in a configuration with its peers not running the protocol, no aggregations will be formed and the switch will function normally (that is, will block redundant paths).

Due to the functionality of a switch, if multiple links were active, a packet would end up “looping” around in those links indefinitely. This problem is well documented and is the reason that bridges implement the Spanning Tree Protocol (STP).

Also, assume that 100 users are attached to each 6C105 chassis through 100 Mbps Ethernet ports. If each user attempted to transfer data out of the wiring closet at the maximum possible rate, there could be up to 10 Gbps (100 users x 100 Mbps) of traffic attempting to leave the chassis over a single gigabit link.

  • Page 378 The port will drop all incoming frames that do not have a VLAN tag. This is a reference to a connection from a switch that passes only untagged traffic. By default, a port designated to pass only untagged frames has all VLANs on its Port VLAN List and is configured to transmit all frames as untagged frames.
  • Page 379: Vlan Operation

    The 802.1Q VLAN operation is slightly different than the operation of traditional switched networking systems. These differences are due to the importance of keeping track of each frame and its VLAN association as it passes from switch to switch or from port to port within a switch. 13.5.2 VLAN Components Before describing the operation of an 802.1Q VLAN, it is important to understand the basic...
  • Page 380: Configuration Process

    Before a VLAN can operate, steps must be performed to configure the switch to establish and configure a VLAN. Enterasys Networks VLAN-aware switches default to operate in the 802.1Q VLAN mode. However, further configuration is necessary to establish multiple logical networks.
  • Page 381: Vlan Switch Operation

    These VLAN tags are added to data frames by the switch as the frames are transmitted out certain ports, and are later used to make forwarding decisions by the switch and other VLAN-aware switches. In the absence of a VLAN tag header, the classification of a frame into a particular VLAN depends upon the configuration of the switch port that received the frame.
  • Page 382: Receiving Frames From Vlan Ports

    The switch receives a frame from Port 1 and examines the frame. The switch notices that this frame does not currently have a VLAN tag. The switch recognizes that Port 1 is a member of VLAN A and classifies the frame as such. In this fashion, all untagged frames entering a VLAN switch assume membership in a VLAN.
  • Page 383: Known Unicasts

    When the switch is powered up, the switch uses its default settings to switch frames like an 802.1Q switch. In this default configuration, all ports are a member of the default VLAN (VLAN 1) including the virtual Host Data Port of the switch, so any port can be used to manage the device as shown in Figure 13-3.
  • Page 384: Switch With Vlans

    Figure 13-3 Switch Management with Only Default VLAN 13.8.3 Switch with VLANs If the switch is to be configured for multiple VLANs, it may be desirable to configure a management-only VLAN. This allows a management station connected to the management VLAN to manage all ports on the switch and make management secure by preventing management via ports assigned to other VLANs.

    VLAN” (or other suitable name) and its VLAN ID. In this example, the VLAN ID is set to 2. An FDB ID is automatically assigned by the switch, so that the Management VLAN has its filtering database to make the VLAN secure. In this example, the FDB ID is 2 and no other VLAN is assigned to this FDB ID.
  • Page 386: Summary Of Vlan Local Management

    No matter how many switches are connected, a management station connected to any port on the same Management VLAN can be used to remotely manage any Enterasys Networks 802.1Q switch in the network as long as the Host Data Port of all the switches are members of the same Management VLAN.

    2. Use the arrow keys to highlight the Egress field of Port 3. NOTE: For the purposes of this walkthrough, Port 3 will be configured. As this port will connect to a single workstation, and is not to be used for switch-to-switch communications, the Egress will be set to UNTAGGED.
  • Page 390: Walkthrough Stage Two, Port 3 Egress Setting

    Now that Port 3 belongs to VLAN 2, we will designate one port as a trunk port for a connection to another VLAN-aware switch. This trunk port will carry tagged frames from all VLANs, allowing VLAN frames to maintain their VLAN ID across multiple switches.
  • Page 391: Walkthrough Stage Three, Port 10 Egress Setting

    NOTE: Since Port 3 will connect to a single workstation, and is not to be used for switch-to-switch communications, the acceptable frame types allowed through this port will be all frame types (tagged and untagged). Since Port 3 will not receive VLAN frames from the work station, it is not necessary to filter frames.
  • Page 392 NOTE: Since Port 10 will be used for switch-to-switch communications, the PVID is left set on the default VLAN value of 1. This associates Port 10 with all VLANs on the switch. Since Port 10 will be used as a trunk port, only tagged frames will be allowed through the port.
  • Page 393: Examples

    This effectively completes the configuration of a single VLAN, assigning it to a port, and configuring the switch to forward the frames received on that port to a trunk port. The trunk port in turn forward the frames as tagged to another switch.

    Figure 13-10 Example 1, Single Switch Operation 13.12.1 Solving the Problem To set up this switch, users will be assigned to two new VLANs, red stations to the Red VLAN, and blue stations to the Blue VLAN. The information below describes how the switch is configured to create these two VLANs and how users are assigned to them.
  • Page 395: Switch Configured For Vlans

    Figure 13-11 Switch Configured for VLANs The switch will now classify each frame received as belonging to either the Red or Blue VLANs. Traffic from one VLAN will not be forwarded to the members of the other VLAN, and all frames transmitted by the switch will be normal, untagged Ethernet frames.

    R1. 1. Station R1 transmits the broadcast frame. The switch receives this frame on Port 1. As the frame is received, the switch classifies it. The frame is untagged, so the switch classifies it as belonging to the VLAN that Port 1 is assigned to, the Red VLAN.

    Example 2, VLANs Across Multiple Switches 13.13.1 Solving the Problem To solve the problem in this example, the users are assigned to VLANs using Switch 4 and Switch 2 as shown in Figure 13-12. Redco users are assigned to the Red VLAN and Blue Industries users to the Blue VLAN.
  • Page 399 By default the port remains as a member of the Default VLAN. With the original classification information inserted in the frame Tag Header, the receiving switch will maintain the original frame classification. GVRP is enabled on this port and will support dynamic VLANs created by GVRP.
  • Page 400 Ingress Filtering: ENABLED GVRP Status: DISABLED This causes the switch to classify all untagged frames received as belonging to the VLAN specified by each port PVID and to replace the previous PVID information in the port VLAN List with the new PVID information. This makes Port 1 part of the Blue VLAN, Port 3 part of the Red VLAN, and both are set to the VLAN frame format of untagged.
  • Page 401: Frame Handling

    Switch 4 updates its Source Address Table in FDB ID 2 if it didn’t already have a dynamic entry for MAC address “Y” in FDB ID 2. Because Switch 4 received the frame on Port 1, it does not forward the frame out that port, but does forward the frame to Port 4.

  • Page 411: Generic Attribute Registration Protocol (Garp)

    The purpose of GVRP is to dynamically create VLANs across a switched network. When a VLAN is declared, the information is transmitted out GVRP configured ports on the switch in a GARP formatted frame using the GVRP multicast MAC address. A switch that receives this frame, examines the frame, and extracts the VLAN IDs.
  • Page 412: How It Works

    A-1, Switch 4, port 1 is registered as being a member of VLAN Blue and then declares this fact out all its ports (2 and 3) to Switch 1 and Switch 2. These two switches register this in the Port VLAN Lists of the ports (Switch 1, port 1 and Switch 2, port 1) that received the frames with the information.
  • Page 413: About Igmp

    Internet Group Management Protocol (IGMP) is a multicast protocol used by routers. This protocol is supported by Enterasys Networks SmartSwitches when operating in the 802.1Q mode to “snoop” the IGMP frames. The multicast information is gleaned from the IGMP frame and a filter is created to send the stream of data only to those end stations that will receive it.
  • Page 414: B.2 Supported Features And Functions

    Ports that receive queries are marked as upstream ports. It is assumed a router exists somewhere off this port, and responses are sent here. If the switch detects a router protocol on a port, that port is also marked as a router port. This keeps the switch from blocking traffic to other routers.
  • Page 415: B.3 Detecting Multicast Routers

    The router(s) sends multicast routing protocol frames that get flooded throughout the network. By snooping on these protocol, the switch will mark ports as connected to a router. The port is put in a “forward all” mode where all multicast frames will be flooded. This allows all types of IP multicast traffic (including IGMP streams) to go to the router.
