From 7a92d44bfa6aeb96f61b95a96b4248a80b5d4544 Mon Sep 17 00:00:00 2001 From: Slawek Kaplonski Date: Thu, 19 Jul 2018 16:00:04 +0200 Subject: [PATCH] [Docs] Add note about Floating IP QoS As it might be confusing for users that ID of QoS policy attached to FIP will be also visible in port's attributes after associate FIP with port this patch adds small note about that in QoS documentation. This patch clarify also rules from which QoS policy will be instelled by L3 agent in case when different QoS polies are associated with a port and a floating IP. Additionally this commit fixes also one typo found in qos configs document.
