SnatConnDropPkg | Packets dropped due to port allocation failures | Packets dropped due to port allocation failures caused by exceeding the connection limit when accessing the same destination endpoint Note: A single EIP provides a finite number of ports for SNAT allocation. Port allocation failures can occur if the concurrent connections to the same destination endpoint exceed the limit and the number of EIPs configured in the SNAT rule is insufficient. If port allocation fails and packet loss keeps increasing, it is recommended to add more EIPs to the SNAT rule configuration. | - | natId | [60s, sum] [300s, sum] |
