Vulnerability
Solution Description and Usage
Suggestion
IP spoofing Enable the anti-IP spoofing
function for MDU.
After anti-IP spoofing is enabled, the
system can prevent users from forging
IP addresses to perform malicious
attacks.
Use this solution for new site
deployment.
13.2.6 Principle of Reliability Data Plan
Reliability planning covers planning of equipment reliability and upstream/downstream
networking protection. Reliability planning helps to achieve high reliability of private line
services.
Equipment Reliability
Protection Scheme Description Suggestion
Main control board 1
+1 protection
The system uses two main control
boards of the same model and
version. The two main control boards
work in the active/standby mode by
default. When the active main control
board fails, the system switches to the
standby main control board to
prevent service interruption.
Mandatory
Power board 1+1
protection
A subrack is configured with two
power boards of the same model and
version, which back up each other.
When one of the power board fails,
the other power board can still
provide power supply to the device
and so the system can still work
properly.
Mandatory
Upstream board 1+1
protection
The system uses two upstream
interface boards of the same model
and version. Each GIU board
provides one upstream port and two
upstream ports are bound together
using Link Aggregation Control
Protocol (LACP). When the active
upstream port fails, traffic will be
transmitted upstream through the
standby upstream port.
This protection scheme is
recommended when the
GIU board is used to
transmit traffic upstream.
