HUAWEI IP Phone 7920
Product Description
2.7.2 eSight Redundancy
HUAWEI IP Phone 7920 supports eSight redundancy. The domain name configured on the
DNS server is mapped to two eSight IP addresses, one active and one standby. When
HUAWEI IP Phone 7920 receives the IP addresses resolved by the DNS server, HUAWEI IP
Phone 7920 first initiates a connection request to the active eSight. If the active eSight fails to
respond, HUAWEI IP Phone 7920 connects to the standby eSight.
2.7.3 Authentication Server Redundancy (Only in EC6.X)
In the EC6.X network environment, HUAWEI IP Phone 7920 supports uPortal server
redundancy. During HUAWEI IP Phone 7920 login authentication, if the active uPortal server
fails, HUAWEI IP Phone 7920 automatically switches to the standby uPortal server to ensure
functional services.
2.7.4 Directory Server Redundancy (Only in EC6.X)
HUAWEI IP Phone 7920 supports directory server redundancy. During directory query, if the
active directory server fails, HUAWEI IP Phone 7920 automatically switches to the standby
directory server for a query.
2.7.5 NTP Server Redundancy
HUAWEI IP Phone 7920 supports NTP server redundancy. During time update, if the active
NTP server fails, HUAWEI IP Phone 7920 automatically switches to the standby NTP server
for time synchronization.
