Dell PowerConnect 6224 User Manual

128 Configuring System Information
• If more than one Unicast device responds, synchronization information is preferred from the device
with the lowest stratum.
• If the servers have the same stratum, synchronization information is accepted from the SNTP server
that responded first.
MD5 (Message Digest 5) Authentication safeguards device synchronization paths to SNTP servers. MD5
is an algorithm that produces a 128-bit hash. MD5 is a variation of MD4, and increases MD4 security.
MD5 verifies the integrity of the communication, authenticates the origin of the communication.
