To let the customers aware about an expected behavior when trying to add dublicate entry of pool-member-IP+port combination in same pool.Symptoms:
1. You are using NSX-T Load-Balancer to host Virtual-Servers2.
Over UI or API you are trying to add a pool-member to a pool and you are getting the similar error,
UI:API:
{
"httpStatus" : "BAD_REQUEST",
"error_code" : 502001,
"module_name" : "policy",
"error_message" : "Errors validating path=[/infra/lb-pools/Test-Pool].",
"related_errors" : [ {
"httpStatus" : "BAD_REQUEST",
"error_code" : 502017,
"module_name" : "policy",
"error_message" : "There are more than one IpAddressPortPair in the IpPortList which have the same IP address 172.16.10.100 and port 22."
} ]
}
3. Additionally on the 'nsxapi.log' on NSX-T Manager you would be seeing the similar error as well,
