I have a stack of two 2920 HP ProCurve switches. They have an IP assigned to them on VLAN 1 of 10.1.7.5 255.255.248.0
I want to change this to 10.1.7.147 255.255.248.0.
When I try to do this via a console connection using Putty I get the following error.
"An interface with the same IP address or subnet or an overlapping network 10.1.7.147/21 already exists."
What would cause this and how can I complete this change?
