Hi everyone!
I've got router as vpn-concentrator which receives vpn site-to-site connections from 10 branches with cisco 881 and cisco 1941.
I started cacti monitoring and found out that there are too many errors on interfaces.

Post "show interface" in text form.

I forgot to mention that it's vyatta, debian + cli like cisco.
i restarted it 2 hours ago and this is the output:
