我试图通过Cisco 2811上的T1端口启动PPP。我最近将固件升级到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个插槽，安装了T1 / E1端口（3个2端口模块和1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 ...
我已经将卡types指定为T1并重新启动。 我可以看到show run输出中的控制器接口，但我仍然没有任何show run或界面中的任何Serial interface ? 输出。 我在下面粘贴了我的完整configuration。 任何洞察力是赞赏。
谢谢，Nathan Alderson

弄清楚了。 只需要在我的控制器上创build通道组：
controller T1 0/0/0 cablelength long 0db channel-group 0 timeslots 1-24
现在我有串行接口！
