DELL PC2708 User Manual

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 PowerConnect 

2708/2716/2724/2748 system can classify according to IPv4 information (DSCP).

The IEEE 802.1p signaling technique is an OSI Layer 2 standard for marking and prioritizing 

network traffic at the data link/MAC sub-layer. 802.1p traffic is classified and sent to the 

destination. No bandwidth reservations or limits are established or enforced. The 802.1p is a spin-

off of the 802.1Q (VLANs) standard.

With a Web-based management interface, the Ethernet Switches’ system can be managed from 

any Web browser. The system contains an Embedded Web Server (EWS), which serves HTML 

pages, through which the system can be monitored and configured.

The PowerConnect 2708/2716/2724/2748 switches support software boot image and software 

download through TFTP.

Remote Monitoring (RMON) is an extension to the Simple Network Management Protocol 

(SNMP), which provides network traffic statistics. RMON defines current and historical MAC-

layer statistics and control objects, allowing real-time information to be captured across the entire 

network. The switches support one RMON group for Ethernet statistics. The system provides a 

means to collect the statistics defined in RMON and to view the results, using the Web 

management interface in the system.
