unable to set mtu 1600


Hi All,

I am running vyos in vmware workstation 12

I have added a nic to vyos VM and trying to set MTU as 1600 … it is returning error

you can view the error on http://www.directupload.net/file/d/4667/jkzv9wvj_png.htm

snapshot attached as well

the error message is
RTNETLINK answers : invalid file
Error setting MTU on dev eth1
interface ethernet eth1 mtu failed

please suggest



Seems like the VMware NIC doesn’t allow > 1500.

Just tested on hyperv (running server 2012R2 , HP desktop PC), setting mtu to 1600 works fine (and broke OSPF neighbor relation…as expected)
