Cisco Cisco 2600 3600 High Performance ATM Advanced Integration Module トラブルシューティングガイド

With AIM−ATM or AIM−ATM−VOICE−30 module installed, you can install VWIC MFT cards in to those
slots. By configuring T1 controllers, you can make it to act like a regular ATM interface. Thus it can offer
ATM adaptation layer 2 (AAL2) and ATM adaptation layer 5 (AAL5) support for low−density T1/E1 data
and voice connections over ATM networks. AIM module allows service providers and enterprise customers to
take advantage of the reliability and quality of service (QoS) available with ATM connectivity.

The following is a sample configuration.

r06#conf t

Enter configuration commands, one per line.  End with CNTL/Z.

r06(config)#controller t1 0/1

r06(config−controller)#mode atm

r06(config−controller)#end

r06#sh int atm0/1

ATM0/1 is up, line protocol is down

  Hardware is ATM T1

  MTU 4470 bytes, sub MTU 4470, BW 1536 Kbit, DLY 20000 usec,

     reliability 0/255, txload 1/255, rxload 1/255

  Encapsulation ATM, loopback not set

  Encapsulation(s): AAL5

  255 maximum active VCs, 256 VCs per VP, 0 current VCCs

  VC idle disconnect time: 300 seconds

  Last input never, output never, output hang never

  Last clearing of "show interface" counters never

  Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0

  Queueing strategy: weighted fair

  Output queue: 0/1000/64/0 (size/max total/threshold/drops)

     Conversations  0/0/256 (active/max active/max total)

     Reserved Conversations 0/0 (allocated/max allocated)

     Available Bandwidth 1152 kilobits/sec

  5 minute input rate 0 bits/sec, 0 packets/sec

  5 minute output rate 0 bits/sec, 0 packets/sec

     0 packets input, 0 bytes, 0 no buffer

     Received 0 broadcasts, 0 runts, 0 giants, 0 throttles

     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort

     0 packets output, 0 bytes, 0 underruns

     0 output errors, 0 collisions, 0 interface resets

     0 output buffer failures, 0 output buffers swapped out

By default, AIM−ATM or AIM−ATM−VOICE−30 modules support 5 bits for VPI ( 0−31 ) and 8 bits for
VCI (0−255 ). However, VPI and VCI can be altered as required using the command  atm vc−per−vp 
under the ATM interface.
