Switch Administration 7-27
Enter the minimum number of packets that must pass through the device before an SNMP rate trap will be sent. It is
recommended to set this value no less than 1000.
Specifying a Network Time Protocol (NTP) Server
Network Time Protocol (NTP) manages time and clock synchronization in a network environment. The switch, which acts as
an NTP client, periodically synchronizes its clock with a master clock on an NTP server. Time synchronization is typically
optional (although recommended) for the switch’s network operations; however, for sites using Kerberos authentication,
time synchronization is required. Kerberos must synchronize the clocks of its Key Distribution Center (KDC) server(s).
Select System Configuration --> NTP Servers from the left menu to enable NTP. The NTP Server screen appars.
1. The field on the left of the Current Time area displays what the switch believes is the current time. Click the Refresh
button to update that time. If an NTP server is configured, the switch will go out to the network to update its current
time.
2. To enable time service on the switch, check the Enable NTP on WS 2000 checkbox and continue with the rest of the
steps below.
% Dropped
The maximum threshold for the total percentage of packets that are dropped for each of the
devices before a trap is sent.
% Undecryptable
The maximum threshold for the total percentage of packets that are undecryptable for each of
the devices before a trap is sent. Undecryptable packets can be the result of corrupt packets,
bad CRC checks, or incomplete packets.
Associated MUs
The maximum threshold for the total number of MUs associated with each of the devices before
a trap is sent.
