About NTP server status
NTP server state information appears in these server tables:
Requested NTP server table—Displays all of the configured NTP server addresses.
Connected NTP server table—Displays all of the servers to which the SteelHeads are actually connected.
When the SCC connects to an NTP server in a public pool (for example, *.riverbed.pool.ntp.org), the hostname doesn't resolve to a single, fixed IP address. Instead, it returns the IP of one server randomly selected from the pool. For example, resolving 0.riverbed.pool.ntp.org may return the IP of the first available server, and that IP is what appears in the connected NTP server table.
This information appears after an NTP server name:
Authentication information; unauthenticated appears after the server name when it isn’t using authentication.
When RiOS has no NTP information about the current server, nothing appears.
