VWIC-2MFT-G703 and E1/PRI Card

Hi,

I'm using an AS5300 with 8E1/PRI Card and a Cisco 1721 with a VWIC-2MFT-G703. I tried to set a multilink connexion between them.

The Problem is that When they are on HDLC encapsulation, both Serial on the 1721 are up but when I set encapsulation PPP in order to set the multilink the serial went down, but if I delete the encapsulation it goes up.

Following my actual config :

AS 5300: controller E1 2 framing NO-CRC4 channel-group 0 timeslots 1-31 ! controller E1 3 framing NO-CRC4 channel-group 0 timeslots 1-31

interface Serial2:0 description LS-1 with Cisco 1721 bandwidth 1984 ip address 192.168.1.1 255.255.255.252 no fair-queue ! interface Serial3:0 description LS-2 with Cisco 1721 bandwidth 1984 ip address 192.168.1.5 255.255.255.252 no fair-queue

When I type sh controller :

Nas-Router#sh controller E1 3 E1 3 is up. Applique type is Channelized E1 - balanced No alarms detected. alarm-trigger is not set Version info of slot 0: HW: 1, PLD Rev: 11 Framer Version: 0x8

Manufacture Cookie Info: EEPROM Type 0x0001, EEPROM Version 0x01, Board ID 0x49, Board Hardware Version 3.1, Item Number 800-3883-02, Board Revision B0, Serial Number 19551402, PLD/ISP Version 0.1, Manufacture Date 10-Apr-2000.

Framing is NO-CRC4, Line Code is HDB3, Clock Source is Internal.

When I type Sh Serial :

Nas-Router#sh int s3:0 Serial3:0 is up, line protocol is down Hardware is DSX1 Description: LS-2 with Cisco 1721 Internet address is 192.168.1.5/30 MTU 1500 bytes, BW 1984 Kbit, DLY 20000 usec, reliability 220/255, txload 1/255, rxload 1/255 Encapsulation PPP, loopback not set Keepalive set (10 sec) LCP Listen Closed: LEXCP, IPCP, CCP, CDPCP, BRIDGECP, LLC2, BACP, IPV6CP Last input 00:00:00, output never, output hang never Last clearing of "show interface" counters 00:19:50 Queueing strategy: fifo Output queue 0/40, 0 drops; input queue 0/75, 0 drops 5 minute input rate 0 bits/sec, 1 packets/sec 5 minute output rate 0 bits/sec, 0 packets/sec 1207 packets input, 14492 bytes, 0 no buffer Received 0 broadcasts, 0 runts, 0 giants, 0 throttles 356 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 356 abort 1395 packets output, 17124 bytes, 0 underruns 0 output errors, 0 collisions, 0 interface resets 0 output buffer failures, 0 output buffers swapped out 0 carrier transitions Timeslot(s) Used:1-31, Transmitter delay is 0 flags

Did anyone face the problem? How can we solve it

Thanks

Are you trying to multilink these two interfaces above? If so, they do not require IP addresses. The multilink group will have the ip address as shown below. Hope this helps.

interface Multilink1 ip address 192.168.1.1 255.255.255.252 no cdp enable ppp multilink ppp multilink group 1

interface Serial2:0 no ip address encapsulation ppp ppp multilink ppp multilink group 1 ! interface Serial3:0 no ip address encapsulation ppp ppp multilink ppp multilink group 1

Hello John,

Thanks for your answer.

I do know that I don't have to put the ip adddress to setup a multlink, but my problem is just when I set PPP encapsulation my Serial goes down and when I delete ot it goes up.

Do you have an idea ?

Regards,

Hi,

Both ends needs to be configured likewise. When running HDLC, does the line protocol come UP? The interface status follows the status of the apropriate controller.

Hi Thomas,

Yes when running HDLC, both of them goes up but when I set PPP encapsulation on both ends I got Link UP Protocol Down.

I tried to reconfigure them on my Lab test and I always got protocol down when encapsulation is PPP, but when using HDLC they goes UP.

Again I took 2 Cisco 1721 and both of them have VWIC-2MFT-G703, I configure them on my Lab test with Encapsulation PPP and here both ends goes UP without any problem.

Maybe I misconfigured the AS5300, so if you have an idea about the correct configuration on Cisco 1721 and the AS5300, ie., What should be done on (Controller and Serial interface) to set PPP encapsulation and to get them work.

Thank you for your help
