Trouble with trunk/LAG/aggregate between 5224 and 6248?
I have 4 switches, 2 are Dell 6248 (sw1 and sw2) and 2 are Dell 5224 (sw3 and sw4). I can create a 2-port trunk between the 6248's no problem, but I cannot create a trunk to the 5224's without it causing a broadcast storm. I have googled for examples and I don't see what I am doing wrong. For now I only have 1 port set as a trunk from sw2->sw3 and from sw3->sw4
Any help is appreciated, I have done this before without any problem with 5324's but I'm having trouble with the 5224's:

FYI - I entered the "switchport allowed vlan remove 1" because it was the only way to get it to allow me to add VLANs to the trunk.

And that is from a 5224? I can't use a port range on the 5224's - I seem to need a 5324 or higher for that.

Here is an example of one of my switches.
To disable the storm control you can try the following.
console(config)# interface ethernet X/gXX
console(config-if)# no storm-control unicast
or if you like to do all the ports.
console(config)# interface range ethernet all
console(config-if)# no storm-control unicast
interface port-channel 1
switchport mode trunk
switchport trunk allowed vlan add 1,101, 250,1000
exit
exit
interface ethernet 1/g37
spanning-tree portfast
mtu 9216
switchport mode trunk
switchport trunk allowed vlan add 1,101, 250,1000
exit
!
interface ethernet 1/g38
spanning-tree portfast
mtu 9216
switchport mode trunk
switchport trunk allowed vlan add 1,101, 250,1000
exit
Don't know if have already tried this, but was worth a shot. Good luck.

I don't have any 54XX switches, but try using individual ports instead of the range.
