Hi
I changed the vcl_test_server / client from TCP to UDP.
Question: Why does the UDP enqueued marked as error_drop?
I get the following in my setup:
how interface
Name Idx State Counter Count
GigabitEthernet0/7/0 1 up rx packets
6
rx bytes
488
tx packets
6
tx bytes
472
drops
6
ip4

GigabitEthernet0/8/0 2 up
local0 0 down
