Hi All,
i am using an 867vae router for my home DSL PPPOA connection. Everything works resonably well and bar a handfull of crc and header errors the connection is stable... but if i do a debug atm errors i get a constant stream of errors as shown below...
I have searched extensively on google for a clue to what this error means but have had no joy...
help please

This kind of messages, obtained during debug, are not indicative of anything wrong.
If you want to optimize you configuration a little, disable 'virtual reassembly'.

Thanks Paolo
Previously ive only used 1801/1841/877 routers and havent seen that error before! I assumed my config must be bad as its a little different using the VDSL controller.
I have disabled the virtual-reassembly as you suggested.
Thanks

Also since you are using PPP and not PPPoE, you can probably reset MTU and TCP MSS to default.
