Access your EVE-NG server using an SSH client and create a uniquely formatted directory: Vios-adventerprisek9-m.vmdk.spa.157-3.m3

The adventerprisek9 feature set embedded in IOS 15.7(3)M3 makes this specific image a versatile tool for various networking scenarios:

: Statefull packet inspection directly inside the simulated router environment. MPLS and Quality of Service (QoS) : This denotes the version of the IOS

: SSH into your EVE-NG server and create a folder for the image:

qemu-img convert -f vmdk -O qcow2 vios-adventerprisek9-m.vmdk.spa.157-3.m3 virtioa.qcow2 Use code with caution. MPLS and Quality of Service (QoS) : SSH
