本帖最后由 xy411381121 于 2018-8-10 16:19 编辑 做自环测试的时候,正常情况应该是端口显示looped吧,为什么会出现端口被都down掉,并反复出现AIS日志?
左边端口现象正常:
NetTime-WAIBU-R2#sho int ser 0/1/1:0
Serial0/1/1:0 is up, line protocol is up (looped)
Hardware is DSX1
Description: DZ
Internet address is 192.200.100.25/30
MTU 1500 bytes, BW 2048 Kbit/sec, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation HDLC, loopback not set
右边端口则被down掉,且反复出现AIS的日志
NetTime-WAIBU-R2#sho int ser 0/1/0:0
Serial0/1/0:0 is down, line protocol is down
Hardware is DSX1
Description: GY
Internet address is 192.200.100.21/30
MTU 1500 bytes, BW 2048 Kbit/sec, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation HDLC, loopback not set
*Aug 8 08:05:54.193: %CONTROLLER-5-UPDOWN: Controller E1 0/1/0, changed state to up

*Aug 8 08:05:56.601: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/1/0:0, changed state to up
*Aug 8 08:05:59.193: %CONTROLLER-5-UPDOWN: Controller E1 0/1/0, changed state to down (AIS detected)
*Aug 8 08:06:01.193: %LINK-3-UPDOWN: Interface Serial0/1/0:0, changed state to down
*Aug 8 08:06:02.193: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/1/0:0, changed state to down
端口配置也都是同一种模版:
controller E1 0/1/0
channel-group 0 unframed
controller E1 0/1/1
channel-group 0 unframed
interface Serial0/1/0:0
description GY
ip address 192.200.100.21 255.255.255.252
interface Serial0/1/1:0
description DZ
ip address 192.200.100.25 255.255.255.252
请问为什么右边在做自环测试时,会出现AIS并端口down掉?
