Dell N3000 (N3048/N3024) – Unsupported LACP fallback

Dell N3000 series looks nice – it’s relatively cheap, supports 2x10G uplink ports, has two power supplies and many features in their spec sheet. Therefore I bought one to test it.

There are however some downsides, which made  this switch useless for me. One of them is missing LACP fallback. With this switch, you can’t configure LACP and have PXE provisioning working at the same time. The switch is in blocking state when there is no LACP connection established.

Unfortunately, lack of this feature is not mentioned on their site.

r1-sw1#configure terminal
r1-sw1(config)#interface Gigabitethernet 1/0/12
r1-sw1(config-if-Gi1/0/12)#channel-group 2 ?
mode       Configure the interface to port-channel mode.
r1-sw1(config-if-Gi1/0/12)#channel-group 2 mode ?
active       Force the port to port-channel with LACP.
on              Force the port to port-channel without LACP.
r1-sw1(config-if-Gi1/0/12)#channel-group 2 mode

Leason learnd: Before you buy a new switch, check the command reference in order to find out that the device you are about to buy supports everything you need.
