Hi Everyone,
I need your help please.... I am trying to use the packet generator for
hicn interest packet.
I saw this example in the documentation (page 14-16):
https://docplayer.net/197638144-Hicn-documentation-release-luca-muscariello-jun-03-2020.html
.
Every time i run this set through the CLI, i get," unknown interface
'TenGigabitEtherneta/0/0 up'
PLEASE HELP ME GUYS!....
