DGS-3100 Series Gigabit Stackable Managed Switch User Manual Managing Stacking Stacking enhances network flexibility by building virtual switches with more ports then are available in a single device. Stacks are managed by stacking member which called Stack Master., All other stacking members serve as ports only.
DGS-3100 Series Gigabit Stackable Managed Switch User Manual Stacking members maintain the assigned Unit ID even after the stacking member is rebooted. The Stack Master may reallocate IDs during system initialization to resolve duplicate ID conflicts. Manually assigned IDs cannot be changed by the Stack Master, even if there is a conflict. Unit ID assignments or modifications are effective only during system initialization, and do not occur during the system uptime.
DGS-3100 Series Gigabit Stackable Managed Switch User Manual Electing a Stacking Master Whenever a stacking member (or more than one) comes up, one of the stacking members is elected to be the stack Master. The Stack Master is selected as follows: • If one of the master enabled stacking members in the stack was set to Force Master by the system administrator (through the GUI – Stacking Master selector), that master enabled stacking member is the Stack Master.
DGS-3100 Series Gigabit Stackable Managed Switch User Manual These stacking members do not participate in the Master Election process, and if no Stack Master is present, the stacking members’ network ports are shut down. Only the stacking ports are operational. Both the Stack Master and all other stacking members carry out a continuous process of Master Discovery by frequently exchanging stack control messages. This allows the stacking members to discover when a stacking member fails or is unreachable.
DGS-3100 Series Gigabit Stackable Managed Switch User Manual Building Stacks – Quick Start The DGS-3100 series supports the following stacking scenarios: • Building a new stack from scratch • Increasing the stack by adding units to an existing stack This section contains the following topics: • Stack Resiliency • Managing a Self-Ordered Stack • Managing a New Manually Ordered Stack Stack Resiliency Topologies of stack can be either Ring or Chain.
DGS-3100 Series Gigabit Stackable Managed Switch User Manual This section contains the following topics: • Building New Manually Ordered Stacks • Adding Stacking Members to an Existing Manually Ordered Stack Building New Manually Ordered Stacks To build new a self ordered stack: 1. Connect the units physically through the stacking ports. 2. Turn on the units, one at a time. 3.
DGS-3100 Series Gigabit Stackable Managed Switch User Manual • – If the new stacking member has a Unit ID of 1 or 2, i.e. the stacking member is a master enabled unit, the new stacking member initiates the Master Election process. However, since the running Stack Master has a longer up-time, it remains the Stack Master and the new stacking member does not become a new Stack Master.
DGS-3100 Series Gigabit Stackable Managed Switch User Manual Unit ID 1, and serving as the stack Backup master, while the already running stacking member with Unit ID 2 remains the active Stack Master. • • • The Stack Master performs Unit ID Allocation and Conflict Resolution process. – If the new stacking member is in the Factory Default mode, the new stacking member is assigned the lowest available Unit ID by the Stack Master.
DGS-3100 Series Gigabit Stackable Managed Switch User Manual – If the Stack Master remains in this sub-group, the behavior is the same as described above. If the Backup Master remains in this sub group the behavior is the same as described in0 - Replacing a Failed Stack Master . NOTE: If a stack is divided into two parts with one section which containing the Stack Master, and the other section - Backup Master was operate.
DGS-3100 Series Gigabit Stackable Managed Switch User Manual Merging Stacks This example assumes that the user would like to merge two working stacks. This creates one stack from two separate stacks. There are two scenarios: If new stacking members are powered down during insertion and then powered up • This is identical to insert stacking members into a running stack, see Replacing Failed Stacking-Members in a Running Stack.
DGS-3100 Series Gigabit Stackable Managed Switch User Manual • A running stacking member group is added to an existing stack, assuming each one of the stack groups has an elected Stack Master. The total of existing stacking members and new stacking members exceeds the maximum allowed number of stacking members in a stack, which is 6 stacking members: – Master Detection and Master Election processes determine the master out of one of two combined stacking groups.

DGS-3100 Series Gigabit Stackable Managed Switch User Manual Configuring VLANs Understanding IEEE 802.1p Priority Priority tagging is an IEEE 802.1p defined standard function designed to provide a means of managing traffic on networks where many different types of data are transmitted simultaneously. It is intended to alleviate problems associated with the delivery of time-critical data over congested networks.
DGS-3100 Series Gigabit Stackable Managed Switch User Manual Term Description Untagging The act of stripping 802.1Q VLAN information out of the packet header. Ingress port A port on a switch where packets are flowing into the switch and VLAN decisions must be made. Egress port A port on a switch where packets are flowing out of the switch, either to another switch or to an end station, and tagging decisions must be made. IEEE 802.1Q (tagged) VLANs are implemented on the switch. 802.
DGS-3100 Series Gigabit Stackable Managed Switch User Manual 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.
DGS-3100 Series Gigabit Stackable Managed Switch User Manual Port VLAN ID Tagged packets (carrying the 802.1Q VID information) can be transmitted from one 802.1Q compliant network device to another with the VLAN information intact. This allows 802.1Q VLANs to span network devices (and the entire network, providing all network devices are 802.1Q compliant). Not all network devices are 802.1Q compliant. Such devices are referred to as tag-unaware. 802.1Q devices are referred to as tag-aware.
DGS-3100 Series Gigabit Stackable Managed Switch User Manual the ingress port. If it does not, the packet is dropped. If it has the same VID, the packet is forwarded and the destination port transmits it on its attached network segment. This process is referred to as ingress filtering, and is used to conserve bandwidth within the switch, by dropping packets that are not on the same VLAN as the ingress port at the point of reception.

DGS-3100 Series Gigabit Stackable Managed Switch User Manual Notes about Trunking on the DGS-3100 Series DGS-3100 series supports up to 32 LAGs per device (or stack). NOTE: A port must belong to the default VLAN when the user is adding the port to a LAG, After adding the port to the LAG, the LAG itself can be joined to other VLAN. When a port is added to a LAG, the port’s configuration is stopping to be active, this configuration will return to be active only after the port will be removed from the LAG.
DGS-3100 Series Gigabit Stackable Managed Switch User Manual Traffic Segmentation The Traffic Segmentation Page enables administrators to force traffic from source ports to bypass the Forwarding Database (FDB), and forward all Unicast, Multicast and Broadcast traffic to the forwarding port,.

Click 4. Define the Unit, Tx, and Rx. fields under Source Port Setting. 5. Click table. to activate the Port Mirroring function.
DGS-3100 Series Gigabit Stackable Managed Switch User Manual Configuring Spanning Tree Spanning Tree Protocol (STP) provides tree topography for any arrangement of bridges, as well as providing a single path between end stations on a network, thus eliminating loops. Loops occur when alternate routes exist between hosts. Loops in an extended network can cause bridges to forward traffic indefinitely, resulting in increased traffic and reducing network efficiency.
DGS-3100 Series Gigabit Stackable Managed Switch User Manual Defining Spanning Tree Global Parameters While Classic STP prevents Layer 2 forwarding loops in a general network topology, convergence can take between 30-60 seconds. This time may delay detecting possible loops and propagating status topology changes.
