Description
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.
The device supports boot image, software and configuration
upload/download via TFTP.
VCT detects and reports copper link cabling occurrences, such as open
cables and cable shorts.
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.
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.
