Sales) to the corporate backbone. It can alleviate bandwidth contention and eliminate server and network bottlenecks. All users that need high bandwidth can connect to high-speed department servers via the switch. You can provide a super-fast uplink connection by using a Gigabit Ethernet/mini-GBIC port on the switch.

There are two mini-GBIC (Gigabit Interface Converter) slots for mini-GBIC transceivers. A transceiver is a single unit that houses a transmitter and a receiver. The switch does not come with transceivers. You must use transceivers that comply with the SFP Transceiver MultiSource Agreement (MSA).
Page 37: The Reset Button
When you use the RESET button all of your configuration settings will be lost. Use the default IP address (192.168.1.1) and user name (admin) and password (admin) to log back into the switch. It may take up to 2 minutes for the switch to restart when you reload the default configuration file.
Page 38: Rear Panel
Make sure you are using the correct power source as shown on the panel. To connect the power to the switch, insert the female end of power cord to the power receptacle on the rear panel. Connect the other end of the supplied power cord to a 100~240V AC, 1.5A power outlet.

Page 63: Vlan
A tagged VLAN uses an explicit tag (VLAN ID) in the MAC header to identify the VLAN membership of a frame across bridges - they are not confined to the switch on which they were created. The VLANs can be created statically by hand or dynamically through GVRP. The VLAN ID associates a frame with a specific VLAN and provides the information that switches need to process the frame across the network.

Strict priority scheduling services the remaining queues using WRR. As traffic comes into the switch, traffic on the highest priority queue, Queue 3 is transmitted first. Only when that queue empties, traffic on the lower priority queues is transmitted using WRR scheduling.
Page 72: Qos Enhancement
The switch allows you to choose one of the following methods for assigning priority to incoming packets on the switch: Port Based QoS - Assign priority to packets based on the incoming port on the switch. See Section 11.4.1 on page DSCP Based QoS - Assign priority to packets based on their Differentiated Services Code Points (DSCPs).

This value changes depending on the number of Tokens Added Per Interval. Tokens The switch uses a “Token Bucket” algorithm to limit the outgoing rate on the ports and Added Per to limit the largest amount of packets that can leave the port in any one instance.
Page 81: Broadcast Storm Control Setup
Broadcast storm control limits the number of broadcast, multicast and unknown unicast (also referred to as Destination Lookup Failure or DLF) packets the switch receives per second on the ports. When the maximum number of allowable broadcast, multicast and unknown unicast packets is reached per second, the subsequent packets are discarded.

Page 133: Dynamic Arp
The ARP table is populated with MAC and corresponding IP address mappings in two different ways. • DHCP Snooping - The switch listens to traffic from a DHCP server on a trusted port and learns IP-to-MAC address bindings by parsing DHCP ACK packets.
Page 134: Viewing Arp Table Entries
Dynamic ARP Aging Time Specify how long (in hours) the switch remembers the learned ARP table entries. Specify “0” to have the switch remember the ARP table entries for an unlimited time period. Trusted ports Packets arriving on trusted ports bypass all Dynamic ARP validation checks, and those arriving on untrusted ports undergo the validation process.
Page 135: Adding Arp Table Entries
Item This is the ARP table entry number. MAC Address This is the MAC address of the device connected to the switch with the corresponding IP address below. IP Address This is the learned IP address of a device connected to a switch port with corresponding MAC address above.
