请教channel-group的配置

[jialingwang4038]

CISCO2811C/K9路由器添加了一块 HWIC-2FE板卡，2个外网口（interface FastEthernet0/0/0和interface FastEthernet0/0/1）链路已连通，请问新的板卡怎么配置controller E1 和channel-group

您好 @jialingwang4038 ，

请按照以下步骤操作。 C2811也有同样的情况。

请问HWIC-2FE板卡，即插即用的，不需要用于申明控制器类型，定义了这个接口吧？

card type e1 2 1 //用于申明控制器类型//数字2表示插槽号//最后的数字1表示模块号：注意不是端口号//

     controller E1 2/1/0  //用于生成接口//即是定义了这个接口

@jialingwang4038 ,

HWIC-2FE确实是2端口快速以太网接口卡，与E1或T1接口无关。

你好，Fast Ethernet HWICs和Multiflex Voice/WAN Interface Cards还是有区别的。

The Cisco Fast Ethernet HWICs are singlewide interface cards, available as a 1-port HWIC (HWIC-1FE) and as a 2-port HWIC (HWIC-2FE), that provide Cisco modular and integrated services routers with additional Layer 3 routed ports.

The T1/E1 Multiflex Voice/WAN Interface Cards are offered in single and dual port versions which can be used and then re-deployed as network requirements change, thereby addressing several applications

关于的支持，还是可以看看如下文档：

Cisco One and Two Port T1/E1 Multiflex Voice/WAN Interface Card

感谢楼上几位大神的回复！

建议先明确要实现的原始需求是什么？对端是什么设备？通过E1线路是要跑成帧还是非成帧？具体配置反而并不是什么大问题，都能找到参考和范例
