I have a L2 Cisco IE4010 with management ip 172.18.16.51 and default gateway 172.18.16.1. A palo alto firewall is directly connected to the switch and the Vlans are correctly configured. The connected interface on the firewall has subinterfaces with ip 10.145.16.1 and10.145.17.1 I am not able to ping 10.145.16.1 from the switch, I create a loop back on the switch with IP 10.145.16.254 and did a ping to 10.145.16.1 with source 10.145.16.254 but still doesnt work. ICMP is allowed on the firewall
Please advise how to fix this
