IOS and Syslog-NG

I have been trying to setup logging via tcp on syslog-ng. all the messages come in fine via udp, but when i configure a tcp source, assign it to the syslog-ng target, etc, then configure the router, i don't get any events. i can see the packets coming in via tcp dump, but syslog-ng won't collect anything. am i missing something. my logging config is below....

logging buffered 4096 informational


logging origin-id hostname

logging source-interface Serial1.1

logging host transport tcp port 5014

Re: IOS and Syslog-NG

Possibly the logging trap command. This can be set to several different levels so set to what best suits your needs.

an example of my basic config below:

logging on

logging #.#.#.#

logging source-interface Loopback0

logging trap notificati
