Can't delete loopback interface

[dimbleby]

Here's an attempt to delete a loopback interface:

$ ip link show lo4
39: lo4: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1632 qdisc noqueue state UNKNOWN mode DEFAULT group default
    link/ether 02:a5:ea:e0:b1:a6 brd ff:ff:ff:ff:ff:ff

$ sudo nas_intf_set.py -o delete lo4
delete
lo4
ianaift:ethernetCsmacd
None
None

$ ip link show lo4
39: lo4: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1632 qdisc noqueue state UNKNOWN mode DEFAULT group default
    link/ether 02:a5:ea:e0:b1:a6 brd ff:ff:ff:ff:ff:ff

As you can see, it just isn't deleted.

I see this in syslog at the time, which I suppose is a clue:

Jan 24 10:24:25 opx_vm opx_nas_daemon[543]: [INTERFACE:NAS-COM-INT-GET], Get request handler was not registered for obj Category 0 and type 4

I imagine that this is related to #40 and #43?

Hello @dimbleby,

I'll look into this issue. Will keep you updated.

Thanks,

We need to fix the python utility script to pass the type as loopback for delete operation.

We can use following command to delete this.
e.g.
cps_set_oid.py -qua target -oper action dell-base-if-cmn/set-interface dell-base-if-cmn/set-interface/input/operation=2 if/interfaces/interface/name=lo4
if/interfaces/interface/type=ianaift:softwareLoopback

Please try the above utility to delete the loopback interface and let me know if you see any issues.

[dimbleby]

Yes, that does the trick - thanks!

Great. I am closing this issue since we have the solution.
