网络工程 - Juniper EX4200 如何从 dot1q-tunneling 接入端口上的 c-vlan 中选择 s-vlan？ - 吾爱随笔录

我如何告诉瞻博网络 EX4200 在 q-in-q（dot1q-tunneling）端口上推送基于 C-VLAN 的特定 S-VLAN？

例如，我想指示 EX4200 使用以下规则执行 Q-in-Q：

1) If a single-tag frame is received on ge-0/0/0 with C-VLAN=41, push S-VLAN=4.
2) If a single-tag frame is received on ge-0/0/0 with C-VLAN=42, push S-VLAN=4.
3) If a single-tag frame is received on ge-0/0/0 with C-VLAN=51, push S-VLAN=5.
4) If a single-tag frame is received on ge-0/0/0 with C-VLAN=52, push S-VLAN=5.

相反，每当要在 ge-0/0/0 上发送双标签帧时，都应该删除（弹出）外部 S-VLAN。

这可以通过瞻博网络 EX4200 完成吗？如果有，请指出具体的配置命令。
