路由

最多支援16條靜態路由
交換機型號如下：

Switch#sh inventory 
NAME: "1", DESCR: "WS-C2960X-48FPS-L"
PID: WS-C2960X-48FPS-L , VID: V02  , SN: FOC1849S5YM

> 這裡是引用
關於型號的說明：
WS-C：cisco交換機字首```
2960X： 2960X系列
FP: Full POE供電  740W，埠POE功率支援15W和30W （802.3af， 803.at）
S：uplink為4個SFP介面
L：LAN-Base

以下是配置靜態路由步驟
配置多於16條並不會報錯，但多於16條以上的配置會直接丟失
以下以刷入20條為例， 刷完後我們看實際生效幾條

當前這臺硬體為LAN-base，如果是LanLite硬體，則完全不支援靜態路由。

另外LAN-BASE與LAN-LITE可以通過換IOS而實現功能互換嗎？
沒戲，硬體寫死的，換不了
