Hello there, As you can no doubt see I am new to this community. I currently have what I "hope" is a simple question. (Setup Cisco 1841 router with X2 Cisco 2960 Catalyst switchesconnected) We currently have a scenario on a Cisco 2960 Catalyst switch with a printer connected to a port on our VLAN1 (A static, non DHCP VLAN) whereby when the HP network printer is attached the printer resets itself every 20 seconds or so. The actual printer is supported by another company and unfortunately I don't have either telnet (from our router) or web access to the printer, but the company who supplied the printer are stating the issue is being brought about by either our router or switch and that the printer has been replaced. I believe they just configure the printers locally with the just the static IP, the DG and the subnet mask for our network, all I believe to be configured correctly. So in summary, a HP printer which has been replaced is connected to any port assigned to VLAN1 on either of the connected switches, configured locally with the IP,SM and DG and as soon as those settings are applied, the printer continually resets itself. So from the switch side, all I can see is: Apr  3 12:36:42: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/7, cha nged state to down Apr  3 12:36:43: %LINK-3-UPDOWN: Interface FastEthernet0/7, changed state to down Apr  3 12:37:09: %LINK-3-UPDOWN: Interface FastEthernet0/7, changed state to up Apr  3 12:37:10: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/7, cha nged state to up Apr  3 12:37:34: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/7, cha nged state to down Apr  3 12:37:35: %LINK-3-UPDOWN: Interface FastEthernet0/7, changed state to down Apr  3 12:38:01: %LINK-3-UPDOWN: Interface FastEthernet0/7, changed state to up Has anyone come across this before ? Any suggestions as to what I can change on the switch or router to prevent this ? Thanks ... View more
