duplicate IP address
On router, I noticed IP address duplication.When I see arp on router it shows one IP address with two different mac address.For IP_PBX, I configured this IP address and other mac-address that I noticed with this IP address that is of Netgear. I have netgear switches model NETGEAR M4100-D10-POE
connected to this router.When I log into the switch, I went to routing > arp > advanced settings and I noticed this MAC address Which I noticed on router.It is connected to Port vlan 1 and status management and type = local
How can I find out this switch is taking duplicate IP address?
Any suggestions or other reasons for this?
