Regarding bandwidth usage

Hi All,

I am facing a problem here , ie,I have two E1 lines and I have created the mulitlink for this, so my total bandwidth should be 4 mbps. I am getting this bandwidth but now problem is that tx and rx load is increasing too much. i checked everything but not able to find the issue. I am posting a show command output for this.

Multilink1 is up, line protocol is up
  Hardware is multilink group interface
  Internet address is 10.88.31.21/30
  MTU 1500 bytes, BW 4096 Kbit, DLY 100000 usec,
     reliability 255/255, txload 15/255, rxload 2/255
  Encapsulation PPP, loopback not set
  Keepalive set (10 sec)
  DTR is pulsed for 2 seconds on reset
  LCP Open, multilink Open
  Open: CDPCP, IPCP
  Last input 00:00:00, output 00:00:00, output hang never
  Last clearing of "show interface" counters 00:09:15
  Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 132
  Queueing strategy: fifo
  Output queue: 0/40 (size/max)
  5 minute input rate 39000 bits/sec, 65 packets/sec
  5 minute output rate 250000 bits/sec, 23 packets/sec
     34333 packets input, 2587928 bytes, 0 no buffer
     Received 0 broadcasts (0 IP multicasts)
     0 runts, 0 giants, 0 throttles
     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
     16742 packets output, 16013759 bytes, 0 underruns
     0 output errors, 0 collisions, 0 interface resets
     0 output buffer failures, 0 output buffers swapped out
     0 carrier transitions

Please help me to sort out this issue.

Thanks

Taran

Do you have a means to capture top talkers?

thats one way to figure out what all the ttraffic is.

Based on what I'm seeing the bandwidth looks fine......You may want to enable ip accounting w/ top talkers on the interfaces. This would be a starting point. How many user are on the LAN, is someone on www downloading or streaming etc...? Also you don't have QOS either so it's a free for all when it comes to traffic. Oh you can setup netflow also along w/ ip accounting.
