Hi
I've got some strange conflict occurring on my switch configuration. This is a new switch that's currently being configured, its a 3560 switch.
While setting up the switch I created the following vlan interface:
interface Vlan10
ip address 10.100.1.2 255.255.255.0
ip helper-address 10.1.1.3
standby 1 ip 10.1.3.1
standby 1 priority 120
standby 1 preempt
standby 2 ip 10.100.1.1
standby 2 priority 120
standby 2 preempt
The "2" portion of the hsrp config was copied into vlan 10 by mistake. I removed it by issuing "no" statements before then pressed "Ctrl-Z", I verified the config on vlan 10, so I now have:
interface Vlan10
ip address 10.1.1.2 255.255.255.0
ip helper-address 10.1.1.3
standby 1 ip 10.1.3.1
standby 1 priority 120
standby 1 preempt
I then created a new vlan interface vlan 20 and copied the following lines in:
interface Vlan200
ip address 10.100.1.2 255.255.255.0
ip helper-address 10.1.1.3
standby 2 ip 10.100.1.1
standby 2 priority 120
standby 2 preempt
Now the once I copied those in I get the following errors:
10.100.1.0 overlaps with Vlan10
10.100.1.1 overlaps with Vlan10
Now this is strange, as vlan 10 no longer contains these subnet statements, so my question is why is the switch getting confused, and how can fix the problem?
Thanks in advance

wr mem
reload
Sometimes devices retain configuration even after issuing no statements, in these cases the device must be reloaded to clear the stale lines.

Since you are implementing HSRP, I'm assuming you have another router/switch with a similar config, did you check you eliminated the 10.100.1.1 from that switch's Vlan10 as well ?
