我的 NX55 VPC 中存在持续的 VLAN 问题。我是 Nexus 环境的新手，所以我需要这方面的建议。
我在 Nexus 5548 VPC（其中所有网关都在我的 Core 6500VSS 中）中创建了 3 个 VLAN。
我的 NX55 中没有 L3 子卡，但我有 LAN_BASE_SERVICE_PKG 许可证来激活该interface-vlan功能。
有人告诉我，由于我没有 L3 子卡，我将无法在 NX55 中启动 L3，因此我将其保留为 L2，而路由将由我的 Core 6500VSS 和 Etherchannel VPC 处理它们之间。有人告诉我，没有 L3 子卡的 LAN_BASE 许可证会导致 SVI 出现问题，所以我已经将其删除，但问题仍然存在。
奇怪的是，3 个 VLAN 中只有 2 个处于 UP 状态，尽管它们都设置在相同的配置中。
