Cisco Cisco Unified IP Interactive Voice Response (IVR) 8.0(1) Guía De Instalación

Before you can upgrade from a remote server, you must download the appropriate 
patch file from Cisco.com to an FTP or SFTP server to which your server (on 
which you are applying the patch) has access.

As a selection of SFTP or FTP requires that you configure network settings so that 
the server can connect to the network, this selection opens with the Auto 
Negotiation Configuration screen. 

To start upgrading from a remote server, complete the following steps:

The Auto Negotiation Configuration window displays. 

The installation process allows you to automatically set the speed and duplex 
settings of the Ethernet network interface card (NIC) by using automatic 
negotiation. You can change this setting after installation.

To use this option, your hub or Ethernet switch must support automatic 
negotiation.

To enable automatic negotiation, choose Yes.

The MTU Configuration window displays. Continue with Step 4.

To disable automatic negotiation, choose No. The NIC Speed and Duplex 
Configuration window displays. Continue with Step 3.

If you chose to disable automatic negotiation, manually choose the appropriate 
NIC speed and duplex settings now and click OK to continue.

The MTU Configuration window displays.

In the MTU Configuration window, you can change the MTU (maximum 
transmission unit) size from the operating system default.

The MTU represents the largest packet, in bytes, that this host will transmit on the 
network. If you are unsure of the MTU setting for your network, use the default 
value.

If you configure the MTU size incorrectly, your network performance can be 
affected.
