The question here is we have a cisco 9200 that is doing our routing. When I plug in a printer into the 9200 with IP configured you are able to get to the IP address with no issue. When the printer is then taken to a Catalyst 1000 you are unable to get to the IP address anymore. When that printer is then brought back and hooked back up to the 9200 you are still unable to get to the IP address.
What would cause the IP to essentially become unusable?

Are you run any dhcp snooping or l2 security?

We do not run dhcp snooping, only l2 security would be ACL's and port security. We were able to put the printer on a different VLAN and it is working. It appears to be something with that vlan and once something is plugged into that switch.

One reason for this could be the vlan relating to that ip isn't being allowed to traverse trunk interconnect in path between the switches?

Seems a bit strange especially if it was working before, Are you re-attaching it to the same port?
What ACLs/L2 security do you have in place?
Do you have stp portfast applied to all edge ports?

Printer is being attached to the same port on the 9200 when it is working and when it is not working. We don't have any ACL's specific to that VLAN. We have verified that the VLAN isn't being pruned by STP.
It is odd that it will work but when connected to 1 specific 1000 it isn't able to connect but when brought back it still won't connect. Don't know if the traffic is getting there and is just being routed back or it isn't getting routed there at all.
