VLAN problem and possible lack of understanding!
Posted on 2009-04-30
I have a problem connecting VLans, it appears to result in a broadcast storm on one of the switches and all the servers are unable to connect: Setup explained below:
I have an HP Switch 3400cl with a 3C_lan on id 1
I have an HP Switch 3400cl with 2 VLANs - 1 is 22 ports on 4D_Vlan id 1 and the is 2 ports on 3c_vlan on id 2
I have a Dell switch with 5E_Vlan on id 0, 4d_vlan on id 1 and 3C_vlan on id 2
If I connect to the 4D switch from the 5E switch I can link to all vlans.
If I connect to the 3C switch from the 5E switch I appear to get a broadcast storm at the 5E end and connection to the attached servers drops off.
Why is this happening?
I don't understand vlans very well so any help would be appreciated
