Auto Image and Configuration Update
379
If the switches are to be assigned a static IP address included in a specified
configuration file (.text) or by a DHCP server, the entries in the *.setup file
that assigns a specific configuration file and image to each switch has the
following format:
MAC_Address Config_File Image_File
For example:
0180.c200.0010 switch-Y.text PC7000vR.5.4.1.stk
1180.c200.0011 switch-Z.text PC7000vR.5.4.1.stk
After a line has been read and implemented by the Auto Configuration
feature, it automatically adds "in-use" to the end of the line to ensure that the
information is not used for the next switch. To replicate the entire USB auto
configuration process, the "in-use" statements from the .setup file need to be
removed. Then, if the process is restarted, the MAC address/IP address
combinations will be ensured for any switch that has previously attempted
upgrade and all other switch upgrades can take place as if for the first time.
What Is the DHCP Auto Configuration Process?
If the USB Auto Configuration fails or is not used, the switch can use a
DHCP server to obtain configuration information from a TFTP server.
DHCP Auto Configuration is accomplished in three phases:
1 Assignment or configuration of an IP address for the switch
2 Assignment of a TFTP server
3 Obtaining a configuration file for the switch from the TFTP server
Auto Configuration is successful when an image or configuration file is
downloaded to the switch from a TFTP server.
Obtaining IP Address Information
DHCP is enabled by default on the Out-of-Band (OOB) interface. It is
disabled by default on VLAN 1, which is the default management VLAN and
includes all switch ports as members. If an IP address has not been assigned,
the switch issues requests for an IP address assignment.
NOTE:
The downloaded configuration file is not automatically saved to startup-
config. You must explicitly issue a save request (copy running-config startup-
config) in order to save the configuration.
