#分享达人# Catalyst 3850 不同 IOS 特性区别

[复制链接]
发表于 2017-9-8 17:35:07 | 显示全部楼层 |阅读模式
3850 是现在比较主流常用的三层交换机,小型企业网关完全没问题,中型企业的汇聚都很合适,性能高,稳定性好。我们在给客户选型或者配置的时候会发现3850软件授权有-L   -S  -E的区别,这三个分别代表的是LAN Base  IP Base IP Services, 那他们具体有什么区别呢?熟悉了他们的区别我们在配置的时候才不会陷入误区,比如你配置不上OSPF, 可能是-L的,你配置不了BGP是因为不是-E 授权。下图有个表格很清晰列出三者区别:
