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

Re: Regarding bandwidth usage

Do you have a means to capture top talkers?

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

Re: Regarding bandwidth usage

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.
