Protection Scheme Description Suggestion
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.
Upstream Networking Protection
Protection Scheme Description Suggestion
Link aggregation
group
Multiple Ethernet ports are bound
together as an aggregation group to
increase the bandwidth and balance
the inbound and outbound load of
each member port. In addition, the
ports in an aggregation group back up
each other, which enhances the
reliability of links.
This protection scheme is
mandatory when the GIU
board is used to transmit
traffic upstream.
Protection group
(Ethernet/STM-1)
A protection group of upstream ports
contains a working port and a
protection port. In normal state, the
working port carries services and the
protection port does not. When the
link at the working port is faulty, the
system automatically switches
services from the working port to the
protection port to ensure normal
service transmission and protect the
uplink.
When the main control
board is used to transmit
traffic upstream, this
protection scheme is
mandatory.
This protection scheme is
recommended when traffic
is transmitted upstream
through STM-1 ports.
NOTE
Link aggregation group and Ethernet protection group usually are not configured at the same time. You are
advised to configure only one of the two protection schemes.
