Native vlan mismatch

[WEERAKOO69BA]

Dear all,

I am getting the following message in our VSS.

Sep  2 05:56:18.501: %CDP-SW1-4-NATIVE_VLAN_MISMATCH: Native VLAN mismatch
 discovered on GigabitEthernet1/2/29 (304), with HQ-DC-CSW-VSS.abc.com
GigabitEthernet2/2/28 (300).

interface GigabitEthernet2/2/28
 description *** F5 Load Balancer Port 2 Primary ***
 switchport
 switchport access vlan 300
 switchport mode access

interface GigabitEthernet1/2/29
 description *** F5 Load Balancer Port 5 Primary ***
 switchport
 switchport access vlan 304
 switchport mode access

Can anyone explain me how I get this message although g2/2/28 and gi 1/2/29 are access ports.?How to fix this issue?Is this interrupt the network(loop)?

Thanks

Enter configuration commands, one per line.  End with CNTL/Z.
sw1(config)#no cdp advertise-v2
