It appears that have a pretty high utilization rate on that 10MB port. It's running
close to 35% in that example, which is very high for 10Mb, half duplex. If you have a
2620 or 2621, set the ethernet port to full duplex.
Then again, now that I think about it, the collision rate, in this case, is acting as
a flow control for traffic headed out to your other sites. Since you only have two
T-1 lines, you're getting close to filling them up to, so changing to full duplex on
the ethernet ports may shift the bottleneck over to your serial lines.
Good luck!
<< I was curious if anyone else had seen this.
We have a 2600 with 2 T1's going to other sights. The
ethernet port connects it to a Bay 450 10/100 switch.
Both switch and router ports are set to 10 / half, but
we're still seeing a collision rate of about 19% This seems
pretty high to me. Anyone have any thoughts?
