N5K-C5548UP,SVI起不来

shanghaiyunji

Level 1
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

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
