5.3.2 Configuring Symmetric Key

Symmetric keys are algorithms for cryptography that use trivially related cryptographic keys for both
decryption and encryption. The encryption key is related to the decryption key, as they may be identical or
there is a simple mechanism to go between keys. The keys represent a shared secret between the switch
and its time resource.
To review existing Symmetric Key configurations, and (if necessary) add a new one:
1. Select Services
2. Select the Symmetric Keys
3. Refer to the

Enter the estimated round-trip delay (between 1 and 999999 seconds) for SNTP
broadcasts between the SNTP broadcast server and the switch. Define the
interval based on the priority of receiving accurate system time frequently.
Typically, no more than one packet per minute is necessary to synchronize the
switch to within a millisecond of the SNTP broadcast server.
