There is problem,that is about catalyst 3850.the topoloy as below:
array connect to c3850 vlan30,and server connect to c3850 vlan 100,interface vlan 100 is server's gateway. array can ping c3850 svi30.
this is the problem:
when i shutdown the server,it won't have arp info about server on c3850,i think it's right.But,when i test on array,use command "telnet 10.100.1.60 8080",the tcp session will be open,i do a capture,found that is gateway's mac address give a response,so,the array think server can work.But,that's a abnormal issue.
I don't know why is that.Do you know,we can discuss it.
