Hi guys,
Here is what I came up with based on what you all told me yesterday. Does
this look correct for routing both tagged and untagged VLANS (one of each
shown here) to the Linux host?
I really appreciate the pointers on this. Since the software isn¹t working
right on the Linux side and

Are you sure you want to disable autonegotiation? Unless the other side
also configures this, the link will not come up.

oh, that looks fine. Just make sure you have the vlans defined on your
switch, otherwise it won't work.

The other side is hard wired to GigE so it's OK in this case.
'switchport nonegotiate' is more tricksie than that - it stops the ends of
the link from negotiating whether they are trunk or access - ie it stops
a host from asking an access port to become a trunk...or a trunk
link from providing just an access layer. its a security mechanism
and isnt to

Indeed yes. You're completely correct on both counts.

That's not link autonegotiation, that's VTP negotiation.
Mostly DTP, to be precise, as others have

All hail SXI which brought in the no vtp enable command!
That's if you aren't using vtp mode transparent already.

I haven't ever tried to make this work before so this is a new application.
I want to use VLAN tagging so that I can create VLANs with numbers like 999,
1000, 1001 and send those VLANs (in different non-overlapping subnets) all
to a Linux machine over a bonded LACP link.
Here's a config snippet
CJ,
We do something similar to this all the time in our HPC environment,
though not with LAGs. You don't need to set an access VLAN, and you do
need to set the portchannel to be in trunk mode - switchport mode trunk.
Here's a snippet from our config for one of our (non-LAG) ports:
It sounds like you intend for the 10.1.1.0/24 subnet to be UNtagged?

I know that the LACP bonding works to the Linux bond0 interface, I think the

.1q tagging works fine over link aggregates (port channels in Cisco speak,
bonded interfaces in linux). Just

According to Cisco Press, the problem is bigger than just VLANs 1002-1005:
Numbers 1001 to 1024 are reserved by Cisco and cannot be configured.
Bonded interfaces aside (I haven't done it with bonded interfaces, so
I'm not sure)
You'll want to use the vconfig command in linux to create your vlan
sub-interfaces. Different distributions package it under different
names. I think it's vlan under debian.
Basic syntax will be something
