Debian 11(Bullseye)에서는 하나의 IP 주소만 표시/사용 가능합니다.

Buster에서 Bullseye로 업그레이드한 후에는 하나의 인터페이스에만 유효한 IPv4 구성이 있습니다.

듀얼 NIC Intel PCIx 카드와 온보드 RealTec NIC(현재 BIOS에서 비활성화됨)가 있지만 NIC #2(및 #3)를 작동시킬 수 없습니다. 시스템은 카드를 감지하고 그에 따라 이름을 변경하지만 링크를 감지하지 않고 할당된 후에 IP 주소를 사용하지 않습니다(정적/dhcp).

dmesg에서:

두 인터페이스 모두 /etc/network/interfaces에 구성되어 있습니다.

allow-hotplug enp1s0f0
iface enp1s0f0 inet static

auto enp1s0f1

ifconfig /ip a는 lo 및 enp1s0f0만 보고합니다.

dhclient가 enp1s0f1을 시작했지만:

ifup이 말했다:

#> ifup enp1s0f1
ifup: interface enp1s0f1 already configured

인터페이스 이름을 지정하면 카드에 대한 정보가 표시됩니다.

#> ifconfig enp1s0f1 
enp1s0f1: flags=4098<BROADCAST,MULTICAST>  mtu 1500
        ether 1c:fd:08:73:60:e1  txqueuelen 1000  (Ethernet)
.
.

인터페이스를 수동으로 올리고,

#> ifconfig enp1s0f1 up

인터페이스에 대한 dhcp 주소를 제공합니다.

그러나 ifconfig는 여전히 IPv4 주소를 표시하지 않습니다.

enp1s0f1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet6 fe80::1efd:8ff:fe73:60e1  prefixlen 64  scopeid 0x20<link>
        ether 1c:fd:08:73:60:e1  txqueuelen 1000  (Ethernet)

그리고 iproute2에서는 라우팅 정보가 표시되거나 사용되지 않습니다.

tcpdump는 인터페이스에 트래픽을 표시합니다.

온보드 RealTec-nic을 사용하여 동일한 동작으로 동일한 단계를 시도했습니다. 또한 이전 Buster-kernel(Linux 버전 4.19.0-16-amd64([이메일 보호됨]) (gcc 버전 8.3.0 (Debian 8.3.0-6)) #1 SMP Debian 4.19.181-1 (2021-03-19) )
