The switch is a WS-C3850-12S. From a fresh startup config, I configured the management port (g0/0) with an ip address of 192.168.1.101, the subnet is 255.255.255.0. My PC has an address of 192.168.1.100, subnet 255.255.255.0.
When I ping the switch from the PC I get replies. When I ping the PC from the switch I get no replies. All antivirus and firewalls have been disabled on the PC.
I turned on debugging for ICMP and saw this:
Switch#
*Feb 13 09:37:13.976: ICMP: echo reply sent, src 192.168.1.101, dst 192.168.1.100, topology BASE, dscp 0 topoid 1

Switch#ping 192.168.1.100
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.100, timeout is 2 seconds:

Success rate is 0 percent (0/5)

Why am I seeing an ICMP echo reply rcvd and getting a success rate of 0 percent from the switch to the PC?

Can you check to make sure the OOB interface is not in its own vrf? If it is, when pinging the PC from the switch use the vrf name (ping vrf ?).

Are VRFs configured by default? I did a startup erase on the switch and reset with the mode button. As far as I can tell no VRF has been configured.

In most new switches, the OOB is in its own vrf, but since you have an older switch I don't remember if the OOB has its own vrf or its just part of the global routing table.
If you issue "sh run" and if there is one, you will see it. Usually it is called "Mgmt-vrf" or something like that.

That was it, I just needed to use the Ping VRF Mgmt-vrf [ip address] command. Thanks Reza
