The most common problem I face when I check the links
status in every network here in sudan that some links
are *half* duplex.
Why? May be there is compatablity issue between
Huawei and cisco.
What is the impact? Huge packet loss and very slow
browsing experience.
How to solve it? I do not know, I just try randomly
all posible settings in both routers cisco & Huawei
till it get resolved.
For discussion:
Do you have this problem in your network? Or have you
faced it before. Please help if you know the right
settings for both routers.
Note: I am serious every network I checked it has this problem.
--------------------------------------------------
I have seen this on our network. For example, I have seen
100Mbps half-duplex be auto-negotiated between two devices
from different manufacturers. I go in and hard code them
when I find them. I use a script to look through the nightly
backups (I get the output from various commands as well as
the configs) to find them.
In cisco's routers:
conf t
int f1/0/1
speed 100
duplex full
exit
wr mem
exit
