From 871dc4287d8c05ff76106dba4f5f8654c24347fe Mon Sep 17 00:00:00 2001 From: Neale Ranns Date: Thu, 29 Mar 2018 01:28:09 -0700 Subject: Detailed stats collection feature Use device-input and interface-output feautre arcs to collect unicast, multicast and broadcast states for RX and TX resp. Since these feature arcs are present only for 'physical' interfaces (i.e. not su-interfaces) counter collection is supported only on parent interface types.
