公司新增了一台CISCO7206,又新买了一张8口E1卡,型号是PA-MC-8TE1。于是打算把原来cisco7000上的一条帧中继割接到新的E1卡上。但是割接失败了,想请大侠们帮帮忙,看一下问题出在哪里:
7000上出来是铜轴电缆,BNC头那种,7206出来是RJ48口,中间用了转接口——不过这个应该不是故障点吧?且听我慢慢道来。
*********************
相关配置
*********************
原7000上相关配置如下:
----------串口---------------
interface Serial1/7
no ip address
encapsulation frame-relay IETF
bandwidth 2048
timeslot 1-31
frame-relay lmi-type ansi
----------子接口-------------
interface Serial1/7.7 point-to-point
description "Link to XXXXX "
ip address *.*.*.158 255.255.255.252
bandwidth 64
frame-relay interface-dlci 22
在7206上相关配置如下:
--------------在5/6上--------------
controller E1 5/6
framing NO-CRC4
channel-group 0 timeslots 1-31 speed 64
interface Serial5/6:0
no ip address
encapsulation frame-relay IETF
frame-relay lmi-type ansi
!
interface Serial5/6:0.1 point-to-point
bandwidth 64
ip address *.*.*.158 255.255.255.252
frame-relay interface-dlci 22
对端为一台CISCO2505,相关配置如下:
-----------------------------------------
interface Serial0
ip address *.*.*.157 255.255.255.252
encapsulation frame-relay IETF
bandwidth 64
frame-relay map ip *.*.*.158 22 broadcast
frame-relay lmi-type ansi

割接过程故障现象如下
*****************************************
线路割接到7206上之后,端口一开始显示DOWN(正常,晚些才起),过几秒钟之后,端口显示为UP

请各位大侠指点指点吧?怎么会明明起来了,又忽然断开了呢? |
