  • Page 23: Stacking Vs. Standalone Operation (Release 4.01)

    DES-3226S Layer 2 Fast Ethernet Switch User’s Guide Stacking vs. Standalone Operation (Release 4.01) By default, the Switch configuration settings allow it to operate as a standalone device, or in a stacked group. It is not necessary to change any settings for the Switch to function in either capacity. However, it is useful to understand how the stacking mode operates in the Switch and the effects if any this may have on configuration settings in a Switch when its stacking status is changed.

  • Page 24: Managing Switch Stacks

    DES-3226S Layer 2 Fast Ethernet Switch User’s Guide For DES-3226S Switch stacks, changes made to the composition of a Switch stack group, that is, adding new Switches or taking Switches out of the stack, require all Switches to restart. The new stacking order is negotiated to reflect the changes made to the group.

  • Page 25: Convert A Standalone Switch To A Stacked Switch

    DES-3226S Layer 2 Fast Ethernet Switch User’s Guide NOTE: For a Switch that has already been configured with many settings already in place, it is a good idea to save the configuration files to a server before changing the stacking mode status. Configuration files can be saved using the CLI, SNMP manager or web manager interface.

  • Page 30: Forwarding And Filtering

    DES-3226S Layer 2 Fast Ethernet Switch User’s Guide • Topology Change A Topology Change trap is sent by the Switch when any of its configured ports transitions from the Learning state to the Forwarding state, or from the Forwarding state to the Blocking state. The trap is not sent if a new root trap is sent for the same transition.

  • Page 31: 802.1W Rapid Spanning Tree

    DES-3226S Layer 2 Fast Ethernet Switch User’s Guide Additional criteria are applied to the forwarding decision. Depending on what header information is being examined, forwarding is permitted or denied based on the packet’s source or destination, its protocol classification, DiffServ code, 802.1p level or VLAN.

  • Page 32: Link Aggregation

    DES-3226S Layer 2 Fast Ethernet Switch User’s Guide The edge port is a configurable designation used for a port that is directly connected to a segment where a loop cannot be created. An example would be a port connected directly to a single workstation. Ports that are designated as edge ports, transition to a forwarding state immediately without going through the listening and learning states.

    DES-3226S Layer 2 Fast Ethernet Switch User’s Guide Figure 5 - 4. IEEE 802.1Q Packet Forwarding 802.1Q VLAN Tags The figure below shows the 802.1Q VLAN tag. There are four additional octets inserted after the source MAC address. Their presence is indicated by a value of 0x8100 in the EtherType field. When a packet’s EtherType field is equal to 0x8100, the packet carries the IEEE 802.1Q/802.1p tag.

    DES-3226S Layer 2 Fast Ethernet Switch User’s Guide Ingress Filtering A port on a Switch where packets are flowing into the Switch and VLAN decisions must be made is referred to as an ingress port. If ingress filtering is enabled for a port, the Switch will examine the VLAN information in the packet header (if present) and decide whether or not to forward the packet.

    DES-3226S Layer 2 Fast Ethernet Switch User’s Guide Multicasting Multicasting is a group of protocols and tools that enable a single source point to send packets to groups of multiple destination points with persistent connections that last for some amount of time. The main advantage to multicasting is a decrease in the network load compared to broadcasting.
