Q: Resolving duplicate IP addresses

Hi,

I get this msg:

0:33:23: %IP-4-DUPADDR: Duplicate address 10.0.0.11 on Ethernet0, sourced by
000
4.003c.0274
0:34:38: %IP-4-DUPADDR: Duplicate address 10.0.0.11 on Ethernet0, sourced by

0:34:58: %IP-4-DUPADDR: Duplicate address 10.0.0.11 on Ethernet0, sourced by
000
4.003c.0274

My config shows:

************* SanJose1#sh arp Protocol Address Age (min) Hardware Addr Type Interface Internet 10.0.0.11 - 00e0.1eb9.9616 ARPA Ethernet0 SanJose1#sh ip int brief Interface IP-Address OK? Method Status Protocol BRI0 unassigned YES not set administratively down down Ethernet0 10.0.0.11 YES manual up up Serial0 unassigned YES not set administratively down down Serial1 192.168.1.2 YES NVRAM down down SanJose1#

I checked all my LAN PCs and another router's Ethernet interface and there is no other 10.0.0.11. How can I tell where the conflict is coming from?

Thanks, V

A quick check on

Check IP on your printers

Thank you both!

Yep, it was one of the printers. Somehow they were forgotten about in my search...I'd say it's time to label my devices. The coffer link is now in my bookmarks. Nice little site.

Thanks again :) V

Mac-address 0004.003c.0274 is LEXMARK INTERNATIONAL, INC. So maybe its printer.
