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

Hi, switchport nonegotiate ! interface GigabitEthernet4/32 [...] switchport nonegotiate Are you sure you want to disable autonegotiation? Unless the other side also configures this, the link will not come up. 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

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:

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
