+Unfortunately, the vethxxxxxx interfaces will cause the physical interface details at the top of the list out of the view of the console, so what we really need is a way to filter this result. This can be done using grep and a filter to format our output.
+    ip -br -c a |grep -v veth
+\\
+This will hide anything containing the letters veth.

+We could refine this output with multiple exclusions using the -e switch:
+    ip -br -c a |grep -v -e "veth" -e "cni0" -e "flannel" -e "kube" -e "internal" -e"lo"
+This give the following output.
