Cisco 2811 缺少串行接口

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 runinterface ?

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！
