Server (4)
 
This type of association is ordinarily created upon arrival of a 
client request message and exists only in order to reply to that 
request, after which the association is dissolved. By operating 
in this mode the host, usually a LAN time server, announces its 
willingness to synchronize, but not be synchronized by the 
peer.
Broadcast (5)
 
A host operating in this mode sends periodic messages regard-
less of the reachability state or stratum of the peers. By operat-
ing in this mode, the host, usually a LAN time server operating 
on a a high-speed broadcast medium, announces its willing-
ness to synchronize all peers, but not be synchronized by any 
of them.
 Note 
The mode of the switch in relation to the remote asso-
ciation is determined when you create the association. 
See NTP Configuration Menu on page 12-6 for more 
information on creating 
NTP
 associations.

The symbols at the very left of this table note the relationship (mode) of the switch to the 
remote association. The section below is a key for interpreting these symbols:
+
The switch is in symmetric active mode.
-
The switch is in symmetric passive mode.
=
The switch is in client mode.
^
The switch is broadcasting to this address.
~
The switch is receiving broadcasts from this address.
*
The switch is currently synchronizing with this address.
