Hi all. I am setting up syslog from an older device (3550) that needs to send from information down to alerts to a syslog server. I have the following config.
show version
Cisco WS-C3550-12G
ios version
flash:c3550-ipservicesk9-mz.122-55.SE7/c3550-ipservicesk9-mz.122-55.SE7.bin
There is some log information showing on the remote destination but the syslog vendor indicates he should be getting more.
I know this is old architecture but need to send everything to a new syslog collector
show run | include syslog
notify syslog contenttype plaintext
show run | include logging
no logging queue-limit
logging rate-limit 50
logging enable
logging size 200
logging event trunk-status
logging event spanning-tree
logging event trunk-status
logging event spanning-tree
logging event trunk-status
logging event spanning-tree
logging history informational>>>>>>>>>>>>>>>>>this I assume will send everything and below
logging source-interface Loopback0
logging host 10.254.164.15 transport udp port 9516
privilege exec level 15 show logging
logging synchronous
When I display the show logging I get below
Trap logging: level informational, 96250 message lines logged >>>>>>>>>>Noted
Logging to 10.254.164.15 (udp port 9516, audit disabled,
authentication disabled, encryption disabled, link up),
4299 message lines logged,>>>>>>>>>>>>>>>>>>>>>>>>>>I would expect this number to be higher
0 message lines rate-limited,
0 message lines dropped-by-MD,
xml disabled, sequence number disabled
filtering disabled
Any/All help is greatly appreciated.

- You need Netflow for flow data.

- Use a more minimized configuration level concerning syslog-setup as in :
logging host 10.254.164.15 transport udp port 9516
logging trap level 6
The latter being an example the digit indicates the logging-level (how far you want to go), check this table concerning their description
Meaning for '7' everything will be logged and or you can expect a lot of syslog-messaging then.

I have another question. I think I know the answer but I want to confirm.
Does syslog show flow data or do we need to use NetFlow.

Thanks M for the quick response. I kinda knew that because I am a Juniper guy and use JFlow so I was just validating.
