Hi,
I have seen some strange behaviour today with VLAN interfaces on bce
interfaces. I am running 6.2 Release on i386.
I have a bce interface setup on a gig-e network with an MTU of 8192 i
attach a vlan interface to this and chnage the vlan if mtu to 1500 as it
has 100Mbit devices on it. This does not seem to affect the MTU of the
bce interface, the VLAN mtu is reported as changed by if config but the
bce is not reported as changed. However I then start to get error
messages saying that the NFS server is not responding as it is sending
packets larger than 1500 bytes.
If I try to raise the mtu of the vlan interface (to 8192 which is the
value that ifconfig reports for bce0) at this stage ifconfig thows an
error saying that the value is incorrect. If I then 'raise' (it already
appears to be set to 8192 according to ifconfig) the mtu of bce0 to 8192
and then set the vlan interface mtu to 8192 the nfs server starts to
work again.
Is this a know bug/problem or should I raise a PR?
Thanks
Tom
