PXE booting LACP hosts on Force10 S50N with FTOS
- by lolwutreddit
Hardware: S50N
Firmware: FTOS 8.4.2.6
Problem: We're trying to PXE boot some servers that are connected via port-channel interfaces with LACP.
Current Work-around: we PXE boot a server with a single interface (eth0), and then use a Perl script to turn up the port-channel interfaces after the server is built.
Details:
Is anyone doing anything similar on Force10 S50 switches with FTOS? If not, is anyone doing this on another S series, or larger chassis-based Force10?
I'm wondering if Native VLAN will solve this, since ports in a port-channel cannot explicitly have a VLAN set, and they don't seem to use the tagged or untagged VLAN that the port channel is in. I will confirm this next (I think it's the only thing I haven't tried)

Cisco: there are plenty of documented ways to solve this issue on IOS and Nexus
Update/Edit: since there seems to be no way to use interface or port-channel mode commands to get the individual interfaces to show up in spanning-tree (rtsp in this case), the ports should never go into a forwarding state. I'm not going to mess with it anymore unless a) someone that has experience passes it on, or b) Force10 comes up with a solution for this (I'm guessing it will only be introduced on other S platforms (S55, S60), since the S50 seems to be near EOL). I'm basing that on the fact that the Open Automation type features are only being supported on the newer switches.
