VBAS Configuration Example

As shown in "VBAS Typical Network", this example describes how
to set trust port of switch A as port 1, cascade port as port 2, trust
port of switch B as port 1.
Configuration of switch A:
zte(cfg)#set vbas en
zte(cfg)#set vbas trust_port 1 en
zte(cfg)#set vbas cascade_port 2 en
zte(cfg)#show vbas
vbas: enabled
trust port : 1
cascade port : 2
Configuration of switch B:
zte(cfg)#set vbas enable
zte(cfg)#set vbas trust-port 1 enable
zte(cfg)#show vbas
vbas: enabled
trust port : 1
cascade port : none

EPON

EPON Overview

With the development of network technology, the speed of back-
bone network and LAN is improved greatly. The last one mile is
the bridge between the network and family user, and now it is the
bottleneck to limit the network development.
The former accessing technologies such as T1/E1 or SONET/SDH
cost too much, and optical accessing technologies such as Cable
Modem requires high cost of network constructing, wireless ac-
cessing technology is restricted by environment and security and
is not easy to launch.
Passive Optical Network (PON) is an accessing technology, which
guarantees the user to obtain enough accessing bandwidth and
controls the network construction cost effectively.
Optical access includes two types:
� Active Optical Network (AON)
� Passive Optical Network (PON)
PON is a pure physical media network, the active device is not
required between the central office end and terminal, which ef-
fectively avoids electromagnetic interference of peripheral equip-
ments, reduces the failure rate of lines and devices, improves the
system reliability and saves the maintenance cost.
PON is transparent to services, so it is applicable to process
the signal with many modes and rates. APON/BPON, GPON
