Étape 1. Confirmer l'incrémentation des CRC
Confirmez que les CRC s'incrémentent sur l'interface physique Ethernet1/1 en générant des
paquets ICMP de 8 000 octets de taille jumbo provenant de l'interface SVI 10 de N9K-1 (qui
possède l'adresse IP 192.0.2.1) destinée à l'interface SVI 10 de N9K-3 (qui possède l'adresse IP
192.0.2.2.3) ..
