![Cisco 2811 缺少串行接口](https://linux22.com/image/522844/Cisco%202811%20%E7%BC%BA%E5%B0%91%E4%B8%B2%E8%A1%8C%E6%8E%A5%E5%8F%A3.png)
我正在尝试通过 Cisco 2811 上的 T1 端口启动 PPP。我最近将固件升级到了 12.4(24)T2:
cisco-2811#show ver
Cisco IOS Software, 2800 Software (C2800NM-ADVENTERPRISEK9-M), Version 12.4(24)T2, RELEASE SOFTWARE (fc2)
它有 4 个安装了 T1/E1 端口的插槽(三个 2 端口模块和一个 1 端口模块):
cisco-2811#show diag
Slot 0:
C2811 Motherboard with 2FE and integrated VPN Port adapter, 2 ports
...
WIC Slot 0:
VWIC2-1MFT-T1/E1 - 1-Port RJ-48 Multiflex Trunk - T1/E1
...
WIC Slot 1:
VWIC2-2MFT-T1/E1 - 2-Port RJ-48 Multiflex Trunk - T1/E1
...
WIC Slot 2:
VWIC2-2MFT-T1/E1 - 2-Port RJ-48 Multiflex Trunk - T1/E1
...
WIC Slot 3:
VWIC2-2MFT-T1/E1 - 2-Port RJ-48 Multiflex Trunk - T1/E1
...
我已将卡类型指定为 T1 并重新启动。我可以在输出中看到控制器接口,但输出中show run
仍没有任何Serial
接口。我已将我的完整配置粘贴在下面。任何见解都值得赞赏。show run
interface ?
谢谢,Nathan Alderson

答案1
搞清楚了。只需要在我的控制器上创建通道组:
controller T1 0/0/0
cablelength long 0db
channel-group 0 timeslots 1-24
现在我有了串行接口!
