WHOA, that's some weird setup.

Everything should work fine on auto/auto. If not both sides of the link
need to at least match, or you will get duplex mismatches which will
cause a lot of problems

This is our standard at the moment

 

Switch ---------Phone Switch Port---------Phone PC Port-------   PC NIC

Auto/Full            Auto/Auto                           100/Full
100/Full  

 

There is a long convoluted history behind these settings but we have not
had any issues until recently.

When you hardcoded to 100/Full, did you hardcode on the switch end and
inside the phone?

 Has anyone run across the following scenario - 

 

 When large amounts of data are transferred between an IP Phone and an
attached PC such as during a Microsoft Office update the update fails.
When the failure occurs the phone shows the status of port 2 (PC Port)
as no link. it was working fine prior to the update starting. This fails
consistently when the phone PC port and the PC NIC is set for 100/full,
always seems to work when both are set to Auto/Auto or when the phone is
bypassed and the PC is plugged directly into the switch port.

 

Tried multiple phones 7941/61/11s. Current phone under test is running
phone load is 41.8-3-3SR2S and we are connected to a 3750 running
12.2.25 SEE2. Going to do more testing but wondering if any one else may
have run across this.

 

Thanks

Steve
