------- Comment From abhir...@in.ibm.com 2018-09-07 05:39 EDT------- I agree that we need to switch to netplan, but that is currently not feasible approach for us. We will keep you updated once we have anything concrete on it.
We expect nmcli also to work as we get the rpm from ubuntu repo. While i was investigating the below case between RHEL and Ubuntu, i noticed the below behaviour. Test case : 1)Create bond 2)Create vlan 3)Deactivate bond #routes for both bond and vlan gets deleted## Hence vlan also gets deactivated 4)Activate bond #Routes get created for bond and not for vlan. ## Hence vlan continues to be in deactivated state? Where in case of RHEL, the route for vlan also was created in step 4, hence the vlan was in activated state. I monitored the system logs during above execution, i did not notice nmcli doing any explicit activation/deactivation logs for vlan when bond was deactivated or activated. So with this i suspect, its underlying kernel taking care of some sort of notification events which is black box to me. Could you please help us inspect on same lines and review the case? What is the expected behaviour with netplan for the above test case? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1790098 Title: vlan created on bond fails auto activation on updating parent network bond Status in Ubuntu on IBM z Systems: Incomplete Status in network-manager package in Ubuntu: Incomplete Bug description: Auto activation of Vlan created over network-bond fails if bond is deactivated and reactivated.

Created a network bond with static IP address (and no IPv6 address); active backup mode; ARP polling; single slave. 2. Created a VLAN using said network bond with static IPv4 address (and no IPv6 address). 3. Can ping from the appliance to a target on both links (the parent bond and the VLAN). 4. Switched to another slave for the created bond 5. Can still ping from the appliance to a target via the parent bond; however, cannot ping to the target via the VLAN. ============================================================================= Detailed steps: 1.
