Hello,
I have 2 Cisco 2811 with 1 AIM module (slot 0) and
1 VWIC-2MFT-E1 module (HWIC 1).I connected them with a back-to-back cable. The pinout of the cable is: 1 ---- 4 2 ---- 5 3 ---- 3 4 ---- 1 5 ---- 2 6 ---- 6 7 ---- 7 8 ---- 8
The picture of the network is:
R1-------------------------------------------R2 ATM0/1/0.100 ATM0/1/0.100 192.168.0.1/24 192.168.0.2/24 E1 0/1/0 E1 0/1/0
On R1, I configured:
--------------------------------------------------------- controller E1 0/1/0 mode atm aim 0 ! controller E1 0/1/1 ! interface ATM0/1/0 no ip address scrambling-payload no atm ilmi-keepalive ! ! interface ATM0/1/0.100 point-to-point ip address 192.168.0.1 255.255.255.0 no snmp trap link-status pvc 1/31 protocol ip 192.168.0.2 broadcast encapsulation aal5snap
---------------------------------------------------------
On router R2, I configured:
--------------------------------------------------------- controller E1 0/1/0 mode atm aim 0 ! controller E1 0/1/1 ! interface ATM0/1/0 no ip address scrambling-payload no atm ilmi-keepalive ! interface ATM0/1/0.100 point-to-point ip address 192.168.0.2 255.255.255.0 no snmp trap link-status pvc 1/31 protocol ip 192.168.0.1 broadcast encapsulation aal5snap
---------------------------------------------------------
I can not ping from R1 to R2. Also, I can not ping from R2 to R1.
Here are some debug output from R1:
--------------------------------------------------------- R1# show ip interface brief Interface IP-Address OK? Method Status Protocol ATM0/1/0 unassigned YES unset up up ATM0/1/0.100 192.168.0.1 YES manual up up

So, on R1 I did: R1(config)# controller e1 0/1/0 clock source line
and R2, I did: R2(config)# controller e1 0/1/0 clock source internal
but, I still have the same problem (I can not ping). Can someone help me??????????????????
Thank you very much.
Eric.
