Cisco 3925如何找到E1接口
作者:佚名    文章来源:本站原创    点击数:    更新时间:2012-2-7    

在项目实施中IT老民工也经常碰到一些简单问题,今天分享两个案例,一个是CISCO3925,一个是CISCO2901,两台设备都是前周设备到货后做加电验收发现,不过问题解决了,今天简单描述了。

      最近两家金融机构采购了两台3925,两台2901路由器,到货后我去现场做设备验收,所有准备工作完成后,加电质检,先拿Cisco2901来说,广域网增加两块WIC-1模块;加电完成后信息提示:

Cisco CISCO2901/K9 (revision 1.0) with 483328K/40960K bytes of memory.
Processor board ID FGL1529214L1

2 Gigabit Ethernet interfaces
DRAM configuration is 64 bits wide with parity enabled.
255K bytes of non-volatile configuration memory.
250880K bytes of ATA System CompactFlash 0 (Read/Write)
没有发现串口信息,通过show inventory:

          系统发现模块,但不支持,原因是Cisco 2901广域网接口是EHWIC接口,因发货错误发了两块WIC-1T 模块,新设备向下可以兼容,WIC-1T 已经停产了,思科不想对产品技术和模块支持,故导致上述问题,通知销售发了两块HWIC-1T模块,设备加电后信息是:

案例II:Cisco3925广域网接口类型是EHWIC,客户增加VWIC2 1MFT-G703板卡,设备加电后信息显示:

Cisco CISCO3925-CHASSIS (revision 1.0) with C3900-SPE100/K9 with 995328K/53248K bytes of memory.
Processor board ID FGL15321131
3 Gigabit Ethernet interfaces

DRAM configuration is 72 bits wide with parity enabled.
255K bytes of non-volatile configuration memory.
255744K bytes of ATA System CompactFlash 0 (Read/Write)

但通过show running命令查看时

没有发现通常看到的CONTROLLER E1 信息,开始认为是IOS不支持,我就升级了IOS,分别是

c3900-universalk9_npe-mz.SPA.150-1.M2.bin

c3900-universalk9-mz.SPA.150-1.M5.bin后,信息依然是没有发现,但通过show run发现一条有价值信息,!
!
! card type command needed for slot/vwic-slot 0/0
! card type command needed for slot/vwic-slot 0/1

通过资料发现,本产品是单独通过一条命令来激活,card type e1 0 0

通过这两次碰到的问题,大家在实施过程中应该提前去思科官网去查看产品手册资料,了解设备性能等,非常简单问题打断我的实施进度,所以各位要所有准备。
