From cd504035015dca62149b57bc07d8e002bd8723b1 Mon Sep 17 00:00:00 2001 From: Christian Poessinger Date: Sat, 15 May 2021 17:03:23 +0200 Subject: vyos.ifconfig: T3532: re-create Q-in-Q interface on protocol change It is not possible to change the VLAN encapsulation protocol "on-the-fly". For this "quirk" we need to actively delete and re-create the VIF-S interface. --- python/vyos/ifconfig/interface.py | 11 +++++++++++ 1 file changed, 11 insertions(+) diff --git a/python/vyos/ifconfig/interface.py b/python/vyos/ifconfig/interface.py index a08872509..048a2cd19 100644 --- a/python/vyos/ifconfig/interface.py +++ b/python/vyos/ifconfig/interface.py @@ -36,6 +36,7 @@ from vyos.template import render from vyos.util import mac2eui64 from vyos.util import dict_search from vyos.util import read_file +from vyos.util import get_interface_config from vyos.template import is_ipv4 from vyos.validate import is_intf_addr_assigned from vyos.validate import is_ipv6_link_local @@ -1308,6 +1309,16 @@ class Interface(Control): vif_s_ifname = f'{ifname}.{vif_s_id}' vif_s_config['ifname'] = vif_s_ifname + + # It is not possible to change the VLAN encapsulation protocol + # "on-the-fly".
