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.
