Cisco Small Business 200 Series Smart Switch Administration Guide
• Preference—Priority of use for the SNTP server.
- Primary—Server with the lowest stratum level. Stratum level is the
distance from the reference clock. Time information is taken from this
server.
- Secondary—Server with the next lowest stratum level after the primary
server. Serves as a backup to the primary server.
- In progress—SNTP server that is currently sending or receiving SNTP
information.
• Status—SNTP server status. The possible options are:
- Up—SNTP server is currently operating normally.
- Down—SNTP server is currently not available.
- Unknown—SNTP server is currently being searched for by the switch.
• Last Response—Date and time of the last time a response was received
from this SNTP server.
• Offset—The estimated offset of the server's clock relative to the local clock,
in milliseconds. The host determines the value of this offset using the
algorithm described in RFC 2030.
• Delay—The estimated round-trip delay of the server's clock relative to the
local clock over the network path between them, in milliseconds. The host
determines the value of this delay using the algorithm described in RFC
2030.
