Logging DHCP Lease information to a syslog server

[MRSOLO]

Hello
I am running DHCP on a Cisco 6500 for my wireless networks (each wireless network is a seperate vlan). For each ip address leased out i need to record/log to a syslog server the date, time, ip address, Mac address and lease expiration time. Can anyone advise how I can accomplish this. Also is it possible to log to more than one device i.e log info from specific interfaces goes to seperate syslog servers ?

Any help greatly appreciated.
Thanks
MRSOLO

Hi,

You could turn on debugging for dhcp...

'debug ip dhcp server events' then configure logging to a syslog server at the appropriate level. This will however send all syslogs of that level, which may include irrelevant messages.

Depending on the sylog server it should be possible to filter out the logs to only include the dhcp requests that you are interested in.

You may also be able to achieve this using SNMP polling/traps.

Can you do this?
router(config)#logging host x.x.x.x
router(config)#logging trap informational
