I hanged it to invalid, feel free to reopen it if you have more details that point to that direction

After the upgrade, I am getting below mentioned logs in northd logs. 2022-09-08T23:08:15.791Z|00064|northd|WARN|Dropped 41 log messages in last 206 seconds (most recently, 201 seconds ago) due to excessive rate 2022-09-08T23:08:15.791Z|00065|northd|WARN|Unknown chassis '' set as options:requested-chassis on LSP '1332fae5-747f-46bd-bd2a-6c3dd47c5b82'. 2022-09-08T23:10:40.927Z|00066|northd|WARN|Dropped 20 log messages in last 145 seconds (most recently, 145 seconds ago) due to excessive rate 2022-09-08T23:10:40.928Z|00067|northd|WARN|Unknown chassis '' set as options:requested-chassis on LSP '1332fae5-747f-46bd-bd2a-6c3dd47c5b82'. 2022-09-08T23:13:12.395Z|00068|northd|WARN|Dropped 62 log messages in last 151 seconds (most recently, 136 seconds ago) due to excessive rate 2022-09-08T23:13:12.395Z|00069|northd|WARN|Unknown chassis '' set as options:requested-chassis on LSP '1332fae5-747f-46bd-bd2a-6c3dd47c5b82'. 2022-09-08T23:15:23.025Z|00070|northd|WARN|Dropped 272 log messages in last 131 seconds (most recently, 125 seconds ago) due to excessive rate 2022-09-08T23:15:23.026Z|00071|northd|WARN|Unknown chassis '' set as options:requested-chassis on LSP '1332fae5-747f-46bd-bd2a-6c3dd47c5b82'. 2022-09-08T23:24:46.723Z|00072|northd|WARN|Dropped 83 log messages in last 564 seconds (most recently, 564 seconds ago) due to excessive rate 2022-09-08T23:24:46.723Z|00073|northd|WARN|Unknown chassis '' set as options:requested-chassis on LSP '1332fae5-747f-46bd-bd2a-6c3dd47c5b82'. Digging it further these LSPs belongs to unbound port i.e the address x.x.x.2 reserve for that port. I have checked this port on OVN and its not showing the chassis binding. I think thats why its generating those logs. +-------------------------+----------------------------------------------------------------------------+ | Field | Value | +-------------------------+----------------------------------------------------------------------------+ | admin_state_up | UP | | allowed_address_pairs | | | binding_host_id | | | binding_profile | | | binding_vif_details | | | binding_vif_type | unbound | | binding_vnic_type | normal | | created_at | 2022-09-08T22:13:44Z | | data_plane_status | None | | description | | | device_id | ovnmeta-e08fb6c2-4a69-4eab-8a04-4be0906d7a69 | | device_owner | network:distributed | | device_profile | None | | dns_assignment | None | | dns_domain | None | | dns_name | None | | extra_dhcp_opts | | | fixed_ips | ip_address='172.16.10.2', subnet_id='2f0e63d0-4e91-4353-82e9-f0752222e443' | | id | d0990b61-8bf8-4ad6-a0a8-a3ccb406ed5f | | ip_allocation | immediate | | mac_address | fa:16:3e:bc:41:12 | | name | | | network_id | e08fb6c2-4a69-4eab-8a04-4be0906d7a69 | | numa_affinity_policy | None | | port_security_enabled | False | | project_id | 3ba8f3bb907448ef8e8f423f883a5303 | | propagate_uplink_status | None | | qos_network_policy_id | None | | qos_policy_id | None | | resource_request | None | | revision_number | 2 | | security_group_ids | | | status | DOWN | | tags | | | trunk_details | None | | updated_at | 2022-09-08T22:13:45Z | +-------------------------+----------------------------------------------------------------------------+ Ammad Ali To manage notifications about this bug go to: https://bugs.launchpad.net/neutron/+bug/1989155/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : yahoo-eng-team@lists.launchpad.net Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
