VPP不能加载UP状态接口

如下Ubuntu 20.04环境。

# cat /etc/issue
Ubuntu 20.04.3 LTS \n \l
#
# uname -a
Linux blackbat 5.13.0-52-generic #59~20.04.1-Ubuntu SMP Thu Jun 16 21:21:28 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

安装完VPP之后，显示接口信息，如下仅有local0接口，没有任何物理接口。

vpp# show interface
              Name               Idx    State  MTU (L3/IP4/IP6/MPLS)     Counter          Count
local0                            0     down          0/0/0/0

日志显示，由于接口处于UP状态，VPP跳过了UP状态接口。

使用nmcli查看网络配置，如下。

# nmcli networking
enabled
#
# nmcli device
DEVICE   TYPE      STATE        CONNECTION
enp6s0   ethernet  connected    Wired connection 5
enp10s0  ethernet  unavailable  --
enp11s0  ethernet  unavailable  --

ens5f1   ethernet  unavailable  --
ens5f2   ethernet  unavailable  --
ens5f3   ethernet  unavailable  --
lo       loopback  unmanaged    --

关闭networking，注意这里时使用的root用户。

# nmcli networking off
#
# nmcli networking
disabled

现在网络接口的状态变成了非管理状态，如下。

$ nmcli device

重启设备，现在VPP加载上了所有的接口：
