Network Running Slow
Posted on 2009-05-01
We have 4 sites here connected by an mpls network managed by a third party supplier.
2 of these sites are identical in terms of amount of users, speed of connection and servers they have to connect to remotely.
However one of the sites is particularly slow, ping runs at the same speed across both the sites, (29ms - 35ms) with no packet loss. However windows share and telnet sessions are very slow at one of the sites.
On reporting this to the third party supplier in typical fashion they have said the line is fine and it is a local issue. Yet no of the other sites are experiencing this, and the servers local to the site are functioning fine. In my mind this proves the issue is with the line, maybe due to something happening locally but this is where the bottleneck is.
I have a feeling something may be using all the bandwidth that shouldn't be, so my question is
Is there some way i can view which IP is using the most bandwidth? I have access to the public snmp strings for the routers (cisco's), I also have remote access to all the computers on the site, i am fairly new to this but could wireshark or a similar product tell me this information?
