My switch won't ping my server. Both are directly connected with each other, and are in vlan 666.
When I initiate a ping from my switch to my server, the switch sends ARP requests. Then the server replies, and the switch adds the mac address in its mac address-table. But after that, it simply does not send a ping. I do not see them on my port monitor capture.
When I initiate from the server to the switch, the switch never replies back to the ARP requests. I have tried adding the entry manually, but then I simply never receive any ICMP echo response.
It should be noted that I can successfully ping another server from my switch.
What can be causing this ? Here is the configuration of the physical port connected to my server:
9300_1#sho run int ten1/1/1 interface TenGigabitEthernet1/1/1 description To DNA enp9s0 switchport access vlan 666 switchport mode access end 9300_1#sho run int vl666 interface Vlan666 ip address 10.168.66.5 255.255.255.0 end
My switch is a Catalyst 9300 Cisco IOS XE Software, Version 16.09.02.
