已解决: N5K-C5548UP,SVI起不来

shanghaiyunji · ‎08-31-2016

网络架构：一台N5K上联两台N7K（VPC），下挂两台N2K，VPC和FEX目前看来状态都正常。
就是配置了一个INTERFACE vlan 251协议down（Vlan251 10.17.251.251 protocol-down/link-down/admin-up）
1、feature inter-vlan已经enable了，
2、相应端口已经划到VLAN 251了，
3、没有配三层卡（是否和这个有关？）
请论坛高手帮忙分析下是啥原因

n5k需要layer 3子卡才能使用3层功能。

CONFIG T
VLAN 251
int vlan 251
5K 55 开始默认都是三层如果是5000 系列必须加三层卡！

要L3的子卡和lanbase的license，至少我之前在N5K物理接口上配IP就遇到过这种问题
