VXLAN config and show utilities by srj102 · Pull Request #870 · sonic-net/sonic-utilities

srj102 · 2020-04-08T10:33:30Z

- What I did

Added support for VXLAN config and commands as described in the PR sonic-net/SONiC#437

- How I did it

Modified the config and show main.py scripts for vxlan support.

- How to verify it

config vxlan add/del and config vxlan evpn_nvo add/del can be verified by using the
"show vxlan interface" command.
config vxlan map/map_range add can be verified by using the "show vxlan vlanvnimap"
command.
show vxlan remote vni/show vxlan remote mac can be verified by populating the
VXLAN_REMOTE_VNI and VXLAN_FDB tables in APP DB.
show vxlan tunnel can be verified by populating the VXLAN_TUNNEL_TABLE in STATE DB.

- Previous command output (if the output of a command-line utility has changed)

- New command output (if the output of a command-line utility has changed)
Please refer to the HLD for outputs.

should it throw error or is it a warning? If it is error use ctx.fail().

This is a utility function which is used by other functions and hence returning True or False.

Seems that this line is the cause of errors during test phase. Probably because of Python version
See an error log after build, i.e. make target/python-wheels/sonic_utilities-1.2-py3-none-any.whl:

... totally 22 times the same.

Probably the reason is #1128

Thanks for the comment. resolved now.

Suggest moving this functionality to separate file, like "vxlan.py" as there is lots of code being added.
Also can you provide some sample config/show output in the description so that can be used as reference?

Suggest use existing is_ipaddress function in this file

This API is not used currently. Removing it.

i think this is specific to vxlan case right? Suggest moving to vxlan.py?

This is a common API will be needed in both vxlan and vrf. So better to keep it in common.

+             click.echo(output)
+
+       vxlan_keys = config_db.keys('CONFIG_DB', "LOOPBACK_INTERFACE|*")


Is there any description to show that only loopback interface can be set to vtep

https://github.com/Azure/SONiC/blob/8645a6a3dd1467153b45ee4f9a08cbf7fd9183d0/doc/vxlan/EVPN/EVPN_VXLAN_HLD.md#512-show-commands

Apart from the show command output there is no other assumption in SONiC components. The VTEP IP should be reachable. Loopback interface is typically used.

No. Updated code.
