I have an HP Procurve 2626 where all devices are on the default Vlan 1. I need to connect the Procurve to the Cisco 3560, but Vlan 1 is shut on the Cisco.
I also have another Procurve that I need to connect to a Cisco 3750. Also default Vlan on HP, but on the 3750, there are multiple Vlans.
Its all down to the vlan configuration on the HP procurve.
The quickest fix, (but a bit sloppy) would be to plug a port on the procurve which will be by default untagged into vlan 1 into a port on the cisco which is native (untagged) into the vlan you want to connect to.
you could also can go into configure mode on the procurve then type:
configure vlan (vlan num) untag (port number)
this will create a vlan and untag the ports you specify into the vlan. You may also want to add an
ip address x.x.x.x 255.255.255.x while under the vlan menu to allow management from that vlan.
