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.

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.
