D-Link DES-3350SR Standalone Layer 3 Switch Gigabit Combo Ports In addition to the 48 10/100 Mbps ports, the Switch features two Gigabit Ethernet Combo ports. These two ports are 1000BASE-T copper ports (provided) and Mini-GBIC ports (optional). See the diagram below to view the two Mini-GBIC port modules being plugged into the Switch.

See the DES-3350SR Command Line Interface Reference Manual on the documentation CD for a list of all commands and additional information on using the CLI.
Page 22: Password Protection
Password Protection The DES-3350SR 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 23: Snmp Settings
The DES-3350SR supports SNMP versions 1, 2c, and 3. You can specify which version of 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.

Show switch command The Switch's MAC address can also be found from the Web management program on the Switch Information (Basic Settings) window on the Configuration menu. The IP address for the Switch must be set before it can be managed with the Web-based manager. The Switch IP address can be automatically set using BOOTP or DHCP protocols, in which case the actual address assigned to the Switch must be known.

D-Link DES-3350SR Standalone Layer 3 Switch RSTP is capable of more rapid transition to a forwarding state – it no longer relies on timer configurations – RSTP-compliant bridges are sensitive to feedback from other RSTP-compliant bridge links. Ports do not need to wait for the topology to stabilize before transitioning to a forwarding state.

Page 45: Vlans
VLANs on the DES-3350SR The DES-3350SR supports IEEE 802.1Q VLANs. The port untagging function can be used to remove the 802.1Q tag from packet headers to maintain compatibility with devices that are tag-unaware (that is, network devices that do not support IEEE 802.1Q VLANs or tagging).
Page 46: Static Vlan Entry

IEEE 802.1Q Tag The EtherType and VLAN ID are inserted after the MAC source address, but before the original EtherType/Length or Logical Link Control. Because the packet is now a bit longer than it was originally, the Cyclic Redundancy Check (CRC) must be recalculated.

Page 52: Sntp Settings
SNTP Settings The DES-3350SR supports Simple Network Time Protocol (SNTP), an adaptation of the Network Time Protocol (NTP). As specified in RFC-1305 [MIL92], NTP is used to synchronize computer clocks in the global Internet. It provides comprehensive mechanisms to access national time and frequency dissemination services, organize the time-synchronization subnet, and adjust the local clock in each participating subnet peer.

The DES-3350SR supports link aggregation groups, which may include from two to eight switch ports each, except for a Gigabit link aggregation group which consists of the two (optional) Gigabit Ethernet ports of the front panel.
Page 61 D-Link DES-3350SR Standalone Layer 3 Switch Figure 7 - 32. Link Aggregation Group Data transmitted to a specific host (destination address) will always be transmitted over the same port in a link aggregation group. This allows packets in a data stream to arrive in the same order they were sent. An aggregated link connection can be made with any other switch that maintains host-to-host data streams over a single link aggregate port.

Page 63: Lacp Port
LACP Port The DES-3350SR supports Link Aggregation Control Protocol. LACP allows you to bundle several physical ports together to form one logical port. After the LACP negotiation, these candidates for trunking ports can be trunked as a logical port. If any one of the connected port pairs does not have LACP capability, these two ports will stand as regular ports until the LACP negotiation is successfully completed.

D-Link DES-3350SR Standalone Layer 3 Switch Appendix B Understanding and Troubleshooting the Spanning Tree Protocol When the spanning-tree algorithm determines a port should be transitioned to the forwarding state, the following occurs: • The port is put into the listening state where it receives BPDUs and passes them to the switch’s CPU. BPDU packets from the CPU are processed.
Page 168: Listening State
D-Link DES-3350SR Standalone Layer 3 Switch Listening State The listening state is the first transition for a port from the blocking state. Listening is an opportunity for the switch to receive BPDUs that may tell the switch that the port should not continue to transition to the forwarding state, but should return to the blocking state (that is, a different port is a better choice).
Page 169: Forwarding State

D-Link DES-3350SR Standalone Layer 3 Switch Disabled State A port in the disabled state does not participate in frame forwarding or STP. A port in the disabled state is virtually non- operational.

Page 171: Troubleshooting Stp
D-Link DES-3350SR Standalone Layer 3 Switch Troubleshooting STP Spanning Tree Protocol Failure A failure in the STA generally leads to a bridging loop. A bridging loop in an STP environment comes from a port that should be in the blocking state, but is forwarding packets.
Page 172: Unidirectional Link
D-Link DES-3350SR Standalone Layer 3 Switch Full/Half Duplex Mismatch A mismatch in the duplex state of two ports is a very common configuration error for a point-to-point link. If one port is configured as a full duplex, and the other port is left in auto-negotiation mode, the second port will end up in half-duplex because ports configured as half- or full-duplex do not negotiate.
Page 173: Resource Errors
Resource Errors The DES-3350SR Layer 2 switch performs its switching and routing functions primarily in hardware, using specialized ASICs. STP is implemented in software and is thus reliant upon the speed of the CPU and other factors to converge. If the CPU is over- utilized, it is possible that BPDUs may not be sent in a timely fashion.
