Configuration on S3600 series switches
Client/server mode
Configure the local S3600 Ethernet switch to operate in the
NTP server mode. In this mode, the remote server serves as
the local time server, while the local switch serves as the
client.
Peer mode
Configure the local S3600 switch to operate in NTP peer
mode. In this mode, the remote server serves as the peer of
the S3600 switch, and the local switch serves as the active
peer.
