Hi,
I have a 3750-X that is configured to log to a syslog server. When I issue the 'show logging' command, the output tells me that the link is 'up' as shown below
Logging to 172.20.1.1 (udp port 514, audit disabled,
authentication disabled, encryption disabled, link up),
28 message lines logged,
0 message lines rate-limited,
0 message lines dropped-by-MD,
xml disabled, sequence number disabled
filtering disabled
Does this mean that the switch knows the syslog messages it is sending out are reaching the destination syslog server because it gets an acknowledgement from the destination?
TIA,

No the switch does not know for sure that the syslog server is up. And there are no acknowledgements if your router is using the normal transmission using UDP on port 514 (which your output says is the case). What the message means is that the switch has a route to the address of the syslog server and that it believes that the link toward the next hop is up.
