NOTICE: The four build-in combination ports on the front panel of the DGS-3312SR can be configured as stacking ports using the CLI. Each stacking module has a single Link/Act LED indicator on its front panel for each IEEE 1394 IN/OUT pair.
Page 17: Rear Panel Description
The Switch supports the D-Link RPS-200 or RPS-500 redundant power supply units. Plug-in Modules The DGS-3312SR Switch is able to accommodate optional plug-in modules in order to increase functionality and performance. Two modules may be installed and used in combination with any of the three available modules. Plug-in modules must be purchased separately.

CAUTION: Do not use the Switch with any redundant power system other than the DPS-200 or DPS-500. Connecting the Console Port The Switch provides an RS-232 serial port that enables a connection to a computer or terminal for monitoring and configuring the Switch.
Page 28: Password Protection
Password Protection The DGS-3312SR does not have a default user name and password. One of the first tasks when settings up the Switch is to create user accounts. If you log in using a predefined administrator-level user name you have privileged access to the Switch’s management software.
Page 29: Snmp Settings
The DGS-3312SR supports the SNMP versions 1, 2c, and 3. You can specify which version of the SNMP you want to use to monitor and control the Switch. The three versions of SNMP vary in the level of security provided between the management station and the network device.

Syslog state Switch Stack Management The DGS-3312SR Switch can be used as a standalone high-capacity Switch or be used in a stacked arrangement. There are two hardware requirements to use the Switch in a stacked group: 1. The proper module(s) must be installed. One or two DEM-540 Stacking modules must be installed in order to use the Switch in a stacked configuration.
Page 44: Configure Stacking
The current order in the Switch stack is also displayed on the front panel of each slave Switch, under the STACK NO. heading. The Stack ID LED display on the front panel of the DGS-3312SR will always display an F (15 in hex), regardless of whether the DGS-3312SR is the master Switch in a Switch stack or in standalone mode.

Page 68: Spanning Tree
The Switch supports 802.1d Spanning Tree Protocol (STP) and 802.1w Rapid Spanning Tree Protocol (RSTP). 802.1d STP will be familiar to most networking professionals. However since 802.1w RSTP has been recently introduced to D-Link managed Ethernet Switches, a brief introduction to the technology is provided below followed by a description of how to set up 802.1 d STP and 802.1w RSTP.
Page 69: Stp Switch Settings
DGS-3312SR Gigabit Layer 3 Switch Port Transition States An essential difference between the two protocols is in the way ports transition to a forwarding state and the in the way this transition relates to the role of the port (forwarding or not forwarding) in the topology. RSTP combines the transition states disabled, blocking and listening used in 802.1d and creates a single state Discarding.

Page 74: Vlans
VLANs are based on layer 3 information, however this does not constitute a ‘routing’ function. The DGS-3312SR and associated DGS-3312SR series Switches allow an IP subnet to be configured for each 802.1Q VLAN that exists on the Switch. That is, a VLAN can be associated or attached to an IP subnet. This represents an improvement in performance since it bypasses any routing functions, packets transferred between subnets are reduced to a “hardware”...
Page 75: Assigning Ip Network Addresses And Subnet Masks To Vlans
VLANs must be configured on the Switch before they can be assigned IP subnets. Furthermore, the static VLAN configuration is specified on a per port basis. On the DGS-3312SR, a VLAN can consist of end-nodes – just like a traditional layer 2 Switch, but a VLAN can also consist of one or more Switches – each of which is connected to multiple end-nodes or network resources.
Page 76: Q Vlan Tags
DGS-3312SR Gigabit Layer 3 Switch Figure 4- 27. 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.

DGS-3312SR Gigabit Layer 3 Switch 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.

Ingress Checking is used to limit traffic by filtering incoming packets that have a PVID does not match the PVID of the port.
Page 82: Qos
DGS-3312SR Gigabit Layer 3 Switch A Port VLAN Identifier is a classification mechanism that associates a port with a specific VLAN and is used to make forwarding decisions for untagged packets received by the port. For example, if port 2 is assigned a PVID of 3, then all PVID untagged packets received on port 2 will be assigned to VLAN 3.
