Gsc3570 flapping Ethernet interface,


@witekprytek: I found following thread via Google:

Could you try to disable port-security to see whether it fixed the issue? Please help to advise the testing result. Sorry I did not have the Cisco switch in hand.

Thank you very much for using Grandstream products.


I have port security disabled

$urity interface GigabitEthernet2/0/18
Port Security : Disabled


@witekprytek: Thanks for the information. So you are saying even with port security disabled, the flapping still happening? If that is the case, it is the chip compatibility issue then. Thanks.


The GSC3570 Ethernet chip is a switch. Iā€™m wondering what spanning tree mode is configured by default in the GSC3570.
