From 98d95b677867c27064d84033dc451ba04c9a2b7b Mon Sep 17 00:00:00 2001 From: Christian Poessinger Date: Tue, 15 Sep 2020 18:54:09 +0200 Subject: bonding: T2515: preserve interface admin state when removing from bond Removing a member from a bond/LACP will turn the physical interface always in admin-down state. This is invalid, the interface should be placed into the state configured on the VyOS CLI. Smoketest on bond interfaces is extended to check this behavior. --- python/vyos/ifconfig/bond.py | 22 ++++++++----- smoketest/scripts/cli/test_interfaces_bonding.py | 24 ++++++++++++++ src/conf_mode/interfaces-bonding.py | 42 +++++++++++++----------- 3 files changed, 59 insertions(+), 29 deletions(-) diff --git a/python/vyos/ifconfig/bond.py b/python/vyos/ifconfig/bond.py index 67dcd2b69..c33cf30bf 100644 --- a/python/vyos/ifconfig/bond.py +++ b/python/vyos/ifconfig/bond.py @@ -1,4 +1,4 @@ -# Copyright 2019 VyOS maintainers and contributors +# Copyright 2019-2020 VyOS maintainers and contributors # # This library is free software; you can redistribute it and/or # modify it under the terms of the GNU Lesser General Public @@ -381,9 +381,14 @@ class BondIf(Interface): # Some interface options can only be changed if the interface is # administratively down if self.get_admin_state() == 'down': - # Delete bond member port(s) + # Remove ALL bond member interfaces for interface in self.get_slaves(): self.del_port(interface) + # Removing an interface from a bond will always place the underlaying + # physical interface in admin-down state!
