base-ip/ipv4/enabled missing from query and does not work

[james-jra]

Setting base-ip/ipv4/enabled does not seem to do anything. I would expect it to act the same as base-ip/ipv6/enabled.

Also it is absent when querying configuration.

Reproduce

• Start with an oper-up interface with IPv4 and IPv6 addresses

  opxUser@opx221_vm:~$ sudo ip addr show dev e101-002-0
  14: e101-002-0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
  link/ether 08:00:27:2d:78:a2 brd ff:ff:ff:ff:ff:ff
  inet 172.28.128.12/24 scope global e101-002-0
     valid_lft forever preferred_lft forever
  inet 10.11.12.2/24 scope global e101-002-0
     valid_lft forever preferred_lft forever
  inet6 fd80:e105:4c24:c3ef::1/64 scope global
     valid_lft forever preferred_lft forever
  inet6 fe80::a00:27ff:fe2d:78a2/64 scope link
     valid_lft forever preferred_lft forever

• Disable IPv6, and the IPv6 addresses are removed (as expected)

  opxUser@opx221_vm:~$ sudo cps_set_oid.py -oper set base-ip/ipv6 name=e101-002-0 enabled=0
  Success
  Key: 1.22.1441815.1441805.
  cps/object-group/return-code = 0
  base-ip/ipv6/enabled = 0
  base-ip/ipv6/name = e101-002-0
  opxUser@opx221_vm:~$ sudo ip addr show dev e101-002-0
  14: e101-002-0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
  link/ether 08:00:27:2d:78:a2 brd ff:ff:ff:ff:ff:ff
  inet 172.28.128.12/24 scope global e101-002-0
     valid_lft forever preferred_lft forever
  inet 10.11.12.2/24 scope global e101-002-0
     valid_lft forever preferred_lft forever

• Disable IPv4, and the transaction succeeds, but nothing changes - it still has IPv4 addresses

  opxUser@opx221_vm:~$ sudo cps_set_oid.py -oper set base-ip/ipv4 name=e101-002-0 enabled=0
  Success
  Key: 1.22.1441814.1441812.
  base-ip/ipv4/enabled = 0
  base-ip/ipv4/name = e101-002-0
  cps/object-group/return-code = 0
  opxUser@opx221_vm:~$ sudo ip addr show dev e101-002-0
  14: e101-002-0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
  link/ether 08:00:27:2d:78:a2 brd ff:ff:ff:ff:ff:ff
  inet 172.28.128.12/24 scope global e101-002-0
     valid_lft forever preferred_lft forever
  inet 10.11.12.2/24 scope global e101-002-0
     valid_lft forever preferred_lft forever

• Query IPv6 configuration - base-ip/ipv6/enabled is present

  
  opxUser@opx221_vm:~$ sudo cps_get_oid.py base-ip/ipv6 base-ip/ipv6/name=e101-002-0

============1.22.1441815.1441805.========== base-ip/ipv6/forwarding = 1 base-ip/ipv6/name = e101-002-0 base-ip/ipv6/vrf-id = 0 base-ip/ipv6/autoconf = 1 base-ip/ipv6/enabled = 0 <------------ base-ip/ipv6/ifindex = 14

* Query IPv4 configuration - base-ip/ipv4/enabled is not present

opxUser@opx221_vm:~$ sudo cps_get_oid.py base-ip/ipv4 base-ip/ipv4/name=e101-002-0

============1.22.1441814.1441812.========== base-ip/ipv4/vrf-id = 0 base-ip/ipv4/name = e101-002-0 base-ip/ipv4/forwarding = 1 base-ip/ipv4/address/prefix-length = 24 base-ip/ipv4/address/ip = 0a0b0c02 base-ip/ipv4/address/prefix-length = 24 base-ip/ipv4/address/ip = ac1c800c base-ip/ipv4/ifindex = 14

Hi @james-jra , it seems this "enabled" attribute is meant for ipv6 only (though I understand it is part of common ip config param group which is bit confusing).

Please refer the description inside the yang model.

https://github.com/open-switch/opx-base-model/blob/dcadb2f62b44fc399b33eed0c0bd721334544569/yang-models/dell-base-ip.yang#L53

Do you have specific requirement to disable ipv4 ?

[james-jra]

Thanks for your feedback We do not have a specific requirement to disable IPv4

If the "enabled" attribute is only relevant for IPv6, do you intend to fix the dell-base-ip YANG model? (remove the "enabled" field from the "common-ip-config-param" group and make it specific to IPv6?)

Thanks James for your response. We will plan to fix the dell-base-ip YANG model.
