This issue can be seen if there is a misconfiguration / mismatch in the UplinkHostSwitchProfile being used.
For example, from desired_state_manager.json file, below is the configuration for the two edges that are part of the same cluster:
Working edge node:"display_name": "edge01",
"failure_domain_id": "########-####-####-####-########aafb",
"host_switch_spec": {
"host_switches": [
{
"cpu_config": [],

{
"key": "UplinkHostSwitchProfile",
"value": "########-####-####-####-########d478"
}
],

{
"device_name": "fp-eth0",
"uplink_name": "uplink-1"
},
{
"device_name": "fp-eth1",
"uplink_name": "uplink-2"
}
Problematic edge node:"display_name": "

","failure_domain_id": "########-####-####-####-########aafb",
"host_switch_spec": {
"host_switches": [
{
"cpu_config": [],
"host_switch_id": "########-####-####-####-########6608",
"host_switch_mode": "STANDARD",
"host_switch_name": "Edge-NVDS",

"device_name": "fp-eth0",
"uplink_name": "uplink-1"
},
{
"device_name": "fp-eth1",
"uplink_name": "uplink-2"
}
From the above, we can see that, both the nodes are mapped to fp-eth0 and fp-eth1. However, the UplinkHostSwitchProfile is different. The working node uses "########-####-####-####-########d478
" and the problematic node uses "########-####-####-####-########4988
".
Now, checking the configuration of these UplinkHostSwitchProfile, we can see that, the working node's UplinkHostSwitchProfile, i.e. ########-####-####-####-########d478
has two uplinks. Whereas, the problematic node's UplinkHostSwitchProfile, i.e. ########-####-####-####-########4988
has four uplinks. However, still the problematic node reported only two uplinks mapped. This is the misconfiguration / mismatch."display_name": "host-uplinkprofile",

For the problematic edge node, using the below steps, change the uplink profile to the correct one:
