•
System Information
To enter system information, do the following:
STEP 1 Click Configuration > System Management > System Information
STEP 2 View or modify the system settings
System Description—Displays a description of the device
•
System Location—Enter the location where the device is physically located
•
System Contact—Enter the name of a contact person
•
System Host Name—Select the host name of this device
•
Default—The default host name (System Name) of these switches is
•
switch123456, where 123456 represents the last three bytes of the device
MAC address in hex format
User Defined—Enter the host name Use only letters, digits, and hyphens
•
Host names cannot begin or end with a hyphen No other symbols,
punctuation characters, or blank spaces are permitted (as specified in
RFC1033, 1034, 1035)
STEP 3 Click Apply to save the values in the Running Configuration file
Management Session Timeout

Overview
Synchronized system clocks provide a frame of reference between all devices
on the network Network time synchronization is critical because every
aspect of managing, securing, planning, and debugging a network involves
determining when events occur Without synchronized clocks, accurately
correlating log files between devices when tracking security breaches or
network usage is impossible
Synchronized time also reduces confusion in shared file systems, as it is
important for the modification times to be consistent, regardless of the
machine on which the file systems reside
For these reasons, it is important that the time configured on all of the devices
on the network is accurate
NOTE:
The device supports Simple Network Time Protocol (SNTP) and when
enabled, the device dynamically synchronizes the device time with time
from an SNTP server The device operates only as an SNTP client, and cannot
provide time services to other devices
