It can limit the number of broadcast packet allowed to pass Ethernet port per second.
When broadcast traffic exceeds the value set by the user, the system will discard
broadcast traffic, thus broadcast traffic will be reduced to a reasonable range to suppress
broadcast storm and avoid network congestion to assure network services of normal
operation. Broadcast storm suppression takes the set rate as the parameter. The smaller
rate means the smaller broadcast traffic allowed to pass.
Support such configuration as port rate, duplex mode and adaptation.
Support line diagnosis analysis and test
ZXR10 5250 supports cable line diagnosis analysis and test. It can check line and
connection and find the location of cable fault to facilitate network management and fault
locating.
GE electrical interface is connected to other devices via network cable. Network cable
has 4 twisted pairs. 100M network cable uses twisted pair 1-2 and 3-6, and 1000M 1-2,
3-6, 4-5 and 7-8. The status of each twisted pair can be detected in line check. Line
statuses are as follows:
1 Open: Open-circuit line
2 Short: Short-circuit line
3 Good: Normal line
4 Broken: Open-circuit or short-circuit line
5 Unknown: Unknown or no result
6 Crosstalk: Line coupling
7 Fail: Failed detection
3.2 Value-Added Service (VAS)
3.2.1 DHCP-based batch upgrade
ZXR10 5250 supports the DHCP-based batch upgrade. By supporting DHCP option66,
67 and 150, the device gets the server address, catalog and filename storing the version.
Option150 stores the server IP address, option66 the version path, and option67 the
version filename. With the information, the device can automatically get the version from
the designated location via FTP or TFTP, which simplifies upgrade procedure, facilitate
operation & maintenance and increase working efficiency.
3.2.2 IPTV
IPTV, known as interactive network TV and launched by carriers based on broadband,
uses IP broadband network and integrates Internet, multimedia and telecom technologies
