验证提示为基本配置
首先我们必须确信，命令在 Cisco IOS软件版本支持。为此我们能执行show version。

7246VXR#show version

我们需要验证DOCSIS配置文件在闪存。

注意文件"silver.cm"使用 DOCSIS CPE Configurator 工具被创建了。对于在CMTS配置被构件您不需要语句"别名TFTP服务器slot0:platinum.cm platinum CM"的 platunum.cm归档因为没有"Cm"文件，它在配置之内驻留。

下一个步骤将验证有线调制解调器联机。我们能达到此带有命令show cable modem。

7246VXR#show cable modem

注意所有有线调制解调器联机。那个连接到接口电缆4/0/U0在网络10.1.4.0。我们能从配置发现他们的 IP地址从称为"cm 白金的" DHCP池被采取。

并且注意各自有线调制解调器带有MAC 地址 0010.7bed.9b23和0010.7bed.9b45，有CPE后边。那些有线调制解调器联机带有默认桥接配置。那些个人计算机用DHCP 配置以便他们能从网络获得他们的IP地址。

以下图片表示，那些个人计算机从称为"pcs-c4的池获得IP地址"。

我们能从此PC也发现TCP/IP设置是自动获得IP地址。
