单个网卡上出现多个 IP 地址的奇怪问题 - OEL linux

然而我得到了两个IP地址。但是当我使用ifconfig命令时，我无法在 ifconfig 命令中看到辅助 IP 地址（10.10.20.51）。当我使用ip addr命令时，我可以在 ifconfig 命令中看到主 IP 地址 (10.10.20.50) 和辅助 IP 地址 (10.10.20.51)。

我的环境：

  • 运行 VMWare ESX 主机上的 OEL 8.3。

以太网配置：

NM_CONTROLLED="yes"
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=none
DEFROUTE=yes
IPv4_FAILURE_FATAL=no
IPV6INIT=no
NAME=ens245
UUID=cb98ce56-5d69-421f-9317-9c26085ea695
DEVICE=ens245
ONBOOT=yes
IPADDR=10.10.20.50
PREFIX=24
DNS1=10.10.20.2
GATEWAY=10.10.20.1
DNS2=10.10.20.3
IPADDR1=10.10.20.51
PREFIX1=24

ifconfig 输出：
