According to this (from 2900XL configuration guide):
When you boot your switch, the DHCP client can be invoked and automatically
request configuration information from a DHCP server under the following
? The configuration file is not present on the switch.
? The configuration file is present, but the IP address is not specified in it.
? The configuration file is present, the IP address is not specified in it, and the
service config global configuration command is included. This command
enables the autoloading of a configuration file from a network server.
If I remove config.text from switch. The switch will boot with default configuration without sending out DHCP discovery.
If I have config.text with "service config" inside, the switch will send broadcast to look for bootp server but still not DHCP.
On 2912XL, I am using "12.0(5)WC17" (c2900xl-c3h2s-mz.120-5.WC17.bin); on 3524XL I am using "12.0(5)WC15" (c3500xl-c3h2s-mz.120-5.WC15.bin).
Can someone explain to me how to config this two switches for DHCP based autoconfiguration? Thanks
