Have you done a debug icmp trace on the cisco switch to see if the packets are making it to the switch? make sure to do a term mon and logging console or monitor on the cisco switch.

change the rule on the pa to deny any any and then check the PA traffic log to see if it's registering ICMP requests from your PC or Switch.

Hi Sue,

In order to ping the firewall's interface, you'll need to attach a management profile allowing ping.  Create a new management profile with ping enabled on the Network Tab > Network Profiles > Interface Mgmt page and then select this management profile on ethernet1/2's interface configuration page.

When you perform the ping operation on the firewall, be sure to specify the source interface IP address that is capable of reaching the switch's IP of  So the command would be "ping source host".  Without specifying a source, the firewall will default to using the IP address assigned to the dedicated management port.  I'm guessing that your management port cannot reach the subnet.
