TCP                     

 

Transport Control Protocol (TCP). TCP connections are defined between 2  

 

 

 

 

 

ports by an initial synchronization exchange. TCP ports are identified by an IP  

 

 

 

 

 

address and a 16-bit port number. Octets streams are divided into TCP  

 

 

 

 

 

packets, each carrying a sequence number.

TFTP Trivial File Transfer Protocol  

The device supports boot image, software and configuration  

 

 

 

 

 

upload/download via TFTP.

Virtual Cable Testing    

 

VCT detects and reports copper link cabling occurrences, such as open  

 

 

 

 

 

cables and cable shorts.

VlAn Support          

 

VlAns are collections of switching ports that comprise a single broadcast  

 

 

 

 

 

domain. Packets are classified as belonging to a VlAn based on either the  

 

 

 

 

 

VlAn tag or based on a combination of the ingress port and packet  

 

 

 

 

 

contents. Packets sharing common attributes can be grouped in the same  

 

 

 

 

 

VlAn.

Web-based Management    

With web-based management, the system can be managed from any web  

 

 

 

 

 

browser. The system contains a Web Server, which serves HTMl pages,  

 

 

 

 

 

through which the system can be monitored and configured. The system  

 

 

 

 

 

internally converts web-based input into configuration commands, MIB  

 

 

 

 

 

variable settings, and other management-related settings.
