[dhcp-relay] Add dhcp_relay show cli #13614

yaqiangz · 2023-02-03T08:49:27Z

Why I did it

Currently the show and clear cli of dhcp_relayis may cause confusion.

How I did it

Add doc for it: [doc] Add docs for dhcp_relay show/clear cli sonic-utilities#2649
Add dhcp_relay config cli and test cases.

show dhcp_relay ipv4 helper
show dhcp_relay ipv6 destination
show dhcp_relay ipv6 counters
sonic-clear dhcp_relay ipv6 counters

How to verify it

Unit test all passed

Why changing IPv6 helper table name?

yaqiangz · 2023-03-06T02:51:37Z

Why changing IPv6 helper table name?

Hi @yxieca, this is not table name in db, it's just test case name. Table name is in line 6, line 22 of mock_config.py ("DHCP_RELAY") which is not changed. Change in line 3 is shown in test results which is in bold below:

test_show_dhcp_relay.py::test_show_dhcp_relay_0_ipv6_with_header <- ../../../../usr/local/lib/python3.9/dist-packages/pyfakefs/fake_filesystem_unittest.py PASSED [ 92%]
test_show_dhcp_relay.py::test_show_dhcp_relay_1_ipv6_without_header <- ../../../../usr/local/lib/python3.9/dist-packages/pyfakefs/fake_filesystem_unittest.py PASSED [ 94%]
test_show_dhcp_relay.py::test_show_dhcp_relay_2_ipv4_with_header <- ../../../../usr/local/lib/python3.9/dist-packages/pyfakefs/fake_filesystem_unittest.py PASSED [ 97%]
test_show_dhcp_relay.py::test_show_dhcp_relay_3_ipv4_without_header <- ../../../../usr/local/lib/python3.9/dist-packages/pyfakefs/fake_filesystem_unittest.py PASSED [100%]

I think such a change is more reasonable and understandable.

Why I did it Currently the show and clear cli of dhcp_relayis may cause confusion. How I did it Add doc for it: [doc] Add docs for dhcp_relay show/clear cli sonic-utilities#2649 Add dhcp_relay config cli and test cases. show dhcp_relay ipv4 helper show dhcp_relay ipv6 destination show dhcp_relay ipv6 counters sonic-clear dhcp_relay ipv6 counters How to verify it Unit test all passed

@yaqiangz Any reason we use “helper” for ipv4 and “destination” for ipv6 ?

yaqiangz · 2023-03-10T01:43:34Z

@yaqiangz Any reason we use “helper” for ipv4 and “destination” for ipv6 ?

Helpers are DHCPv4 only concept, DHCPv6 it use relay destination.

Thanks, i understand we use this terminology is SONiC. Could you point me towards an RFC or something where this terminology is used/defined. I tried to search but couldn't find it.

helper address is first known as ip helper address (not only for dhcp), it's v4 only concept. Not sure which RFC mentioned it first, it may first mentioned in cisco ios-cli https://www.ciscopress.com/articles/article.asp?p=330807&seqNum=9
