xterm串口设置 sja1105p 设置 switch 物理主接口 在 DSA (Distributed Switch Architecture) 架构中，end1 只是一个数据通道（Conduit）。当你连接了 SJA1105 交换机后，你不应该直接在 end1 上配置 IP 地址。
设置好netplan之后，直接设置网桥属性 设置端口隔离即可isolate_ports.sh 并执行
#!/bin/bash ethtool -K end1 rx-vlan-filter off echo "Enabling VLAN filtering on br0..." ip link set dev br0 type bridge vlan_filtering 1 echo "Clearing default VLAN 1 from ports..." bridge vlan del dev br0 vid 1 self for i in {1..4}; do bridge vlan del dev swp$i vlan 1 done echo "Assigning isolated VIDs to ports..." bridge vlan add dev swp1 vid 11 pvid untagged bridge vlan add dev swp2 vid 12 pvid untagged bridge vlan add dev swp3 vid 13 pvid untagged bridge vlan add dev swp4 vid 14 pvid untagged echo "Configuring CPU port (br0) to accept all VIDs..." bridge vlan add dev br0 vid 11 untagged self bridge vlan add dev br0 vid 12 untagged self bridge vlan add dev br0 vid 13 untagged self bridge vlan add dev br0 vid 14 untagged self bridge vlan add dev br0 vid 10 pvid untagged self bridge vlan add dev swp1 vid 10 bridge vlan add dev swp2 vid 10 bridge vlan add dev swp3 vid 10 bridge vlan add dev swp4 vid 10 echo "Isolation configuration complete."
禁用 CPU 网卡的 VLAN 接收过滤

🚀 后面的操作可以不用了，不用看
ip addr flush dev end1 ip link set swp1 up ip link set swp2 up ip link set swp3 up ip link set swp4 up sudo ip link add name br0 type bridge sudo ip link set br0 up ip link set swp1 master br0 ip link set swp2 master br0 ip link set swp3 master br0 ip link set swp4 master br0 ifconfig end1 0.0.0.0 ifconfig br0 172.16.2.100 netmask 255.255.255.0
ip link show type bridge bridge link show bridge fdb show dev br0 ip link set br0 up ip link del br0
switch 端口测试 内部通路测试：自环测试 (Loopback) 要测试 end1 (CPU) 与 SJA1105 内部端口是否通畅，最简单的方法是在 swp 端口上做回环。
ip addr add 10.0.0.1/24 dev swp1 ip addr add 10.0.0.2/24 dev swp2 ip link set swp1 up ip link set swp2 up ping -I swp1 10.0.0.2
如果能 Ping 通，说明：CPU -> end1 -> SJA1105 -> swp1 -> 网线 -> swp2 -> SJA1105 -> end1 -> CPU 这条路径全线贯通
使用 tcpdump 抓包观察 (验证 CPU Port 转发) 在 CPU 端启动监听：
注意：在 DSA 架构下，end1 上的包通常带有特殊的 Tag（SJA1105 专用头部），普通 tcpdump 可能识别为未知协议，但只要有流量计数增加就说明通路正常
