+> Arista devices use interface names in the a/b format (for example, Ethernet1/1). However, because ARM resource IDs use / as a delimiter, this format is not permitted in ARM‑based resource names. As a workaround, NNF employs an a‑b convention for interface resource naming (such as Ethernet1‑1) in ARM contexts.
+>Important: All metrics and logs will continue to report the interface using the original a/b naming format (e.g. Ethernet1/1), even though ARM resource names always substitute the slash (/) with a hyphen (-).
