Auto Negotiation Auto negotiation allows an Ethernet switch to advertise modes of operation. The auto negotiation function provides the means to exchange information between two Ethernet switches that share a point- to-point link segment, and to automatically configure both Ethernet switches to take maximum advantage of their transmission capabilities. Port advertisement allows the system administrator to configure the port speeds advertised. Jumbo Frames Support Jumbo frames are frames with

MAC Address Supported Features MAC Address Capacity Support The PowerConnect 2808, 2816, 2824 switches support a total of 8K MAC addresses, and the PowerConnect 2848 supports a total of 16K MAC addresses. Auto-Learning MAC Addresses The switch enables MAC address auto-learning from incoming packets. The MAC addresses are stored in the Bridging Table. Automatic Aging for MAC Addresses MAC addresses from which no traffic is received for a given period of time are aged out. This prevents the Bri

• Short-Reach — Reduction of power over Ethernet cables shorter than 40m. IGMP Snooping Internet Group Membership Protocol (IGMP) Snooping examines IGMP frame contents, when they are forwarded by the device from work stations to an upstream Multicast router. From the frame, the device identifies work stations configured for Multicast sessions, and which Multicast routers are sending Multicast frames. Port Mirroring The port mirroring mechanism monitors and mirrors network traffic by forwardin

Class of Service (CoS) Features The PowerConnect 28xx system enables users to define various services for traffic classes of service. The underlying mechanism for supporting bandwidth management and control is based on the use of multiple priority queues for classifying traffic. The switches support four queues per port. A CoS is defined by the user, whereby packets are related to the same Class of Service. After a packet has been classified, it is assigned to one of the queues. The PowerConn

2 Hardware Description Switch Port Configurations PowerConnect 28xx Front and Back Panel Port Description The Dell™ PowerConnect™ 28xx switches use 10/100/1000BASE-T ports on the front panel for connecting to a network. The Gigabit Ethernet ports can operate at 10, 100 or 1000 Mbps. These ports support auto- negotiation, duplex mode (Half or Full duplex), and flow control. The combo 1000 Mbps optical ports can only operate at 1000 Mbps, full-duplex mode. The following figures illustrate the fr
