Can ping from the Router but not the switch

[sean.a.mackenzie1]

Having an issue where we are not able to ping one of a clients systems (10.32.160.30) from the switch they are plugged into.  However, we can ping the system from router.  Can see the IP an MAC in the ARP table on the router and can see the MAC associated to the port on the switch. As a comparison, there is an identical system (10.32.160.19) that is plugged into another port on the same switch using the same vlan that is communicating just fine. Looking for any advice on what to check for the system that can't ping from the switch.

Can ping the both of the clients systems from the router:

Can't ping 10.32.160.30 from the switch, but can ping 10.32.160.19:

Any help would be appreciated,

Hello,

can the router ping the switch ? Post the full configs of both the router and the switch...

Hello

Seems a bit strange as they seem to be in the same subnet however Is it possible the switch or host has a different subnet mask then the other host that is reachable from switch and router?

Hi,

You can perform a packet capture on the switch to see what exactly is happening - if it is sending the ICMP packets.

Also check the arp table on the switch.
