%IPADTBL-N-IPDUPLICATE: Duplicate IP address Cisco SG300

 

I'm getting this error on a cisco SG300

%IPADTBL-N-IPDUPLICATE: Duplicate IP address 192.168.120.137 from MAC e4:c7:22:e9:87:98 was detected on VLAN 1, port gi10, aggregated (6)

so I changed the Vlan1 address to 192.168.120.236 bit I get the same error

 %IPADTBL-N-IPDUPLICATE: Duplicate IP address 192.168.120.236 from MAC e4:c7:22:e9:87:98 was detected on VLAN 1, port gi10

also when I do a sh run it doesn't display each port's config as it would on say a 2960.

sh run

nmysw06
v1.3.0.62 / R750_NIK_1_3_647_260

Try configuring the following:

nmsp attachment suppress
no ip device tracking max

at the interface level on the device connected to SG300 on Gi10.
