How to get logs from Cisco Router 2911?

[VCsupport17]

Hello Community,

Is there a way to get the logs from our Cisco 2911 router? I need to get the logs from the previous weeks to check if the interfaces went down or any issue related to the connectivity.

We don't have syslog server. Is there a simple commands to get the logs? 

Thanks in advance.

Hi

Logs are only available if you have set them up to store , by default it will store a buffer of 4096 , that will unlikely contain last weeks logs , that's the command below

to set them up for future use ... logging buffer 100000

also when a router reboots it loses its logs

show logs
