Ethernet speed and duplex configuration in IP Phone


We need to disable ethernet auto-negotiation in about 1000 IP Phones, because many PCs that will be connected to them fail to properly auto-negotiate (old ethernet cards).  We will configure them as 100Mbps/Full Duplex.

The problem: We don´t find any related place to configure this in CUCM Web Admin, so we just use the settings interface in the phone itself.  That isn´t scalable to 1000 phones.

Does any one know some place in web admin to set speed and duplex in phones?? or maybe some 3rd party software??

Thanks and regards

Ethernet speed and duplex configuration in IP Phone

The setting on the device configuration page I think you're looking for is called "Switch Port Remote Configuration", default is disabled, other options are Auto / 10 Half / 10 Full / 100 Half / 100 Full / 1000 Full.  If this is what you're looking for the Bulk Administration Tool (BAT) can be used to change this in bulk on all your phones.
