TFTP server IP address (option 150), if it is available. If the TFTP server IP address is not available,

the DHCP client requests the TFTP file from the DHCP server.

The TFTP configuration download and update step

NOTE

This process only occurs when the client device reboots, or when Auto-Configuration has been

disabled and then re-enabled.

1. When the device reboots, or the Auto-Configuration feature has been disabled and then re-enabled,

the device uses information from the DHCP server to contact the TFTP server to update the

running-configuration file:

• If the DHCP server provides a TFTP server name or IP address, the device uses this information

to request files from the TFTP server.

• If the DHCP server does not provide a TFTP server name or IP address, the device requests the

configuration files from the DHCP server.

2. The device requests the configuration files from the TFTP server by asking for filenames in the

following order:

• bootfile name provided by the DHCP server (if configured)

• hostnameMAC-config.cfg, for example:

FCX001p-Switch0000.005e.4d00-config.cfg

• hostnameMAC.cfg, for example:

FCX002p-Switch0000.005e.4d00.cfg

• brocade.cfg (applies to all devices), for example:

brocade.cfg

• <fcx | icx>-<switch | router>.cfg (applies to Layer 2 or Layer 3 devices), for example:

fcx-switch.cfg

(FCX Layer 2)

icx-switch.cfg

(ICX Layer 2)

fcx-router.cfg

(FCX Layer 3)

icx-router.cfg

(ICX Layer 3)

If the device is successful in contacting the TFTP server and the server has the configuration file,

the files are merged. If there is a conflict, the server file takes precedence.

If the device is unable to contact the TFTP server or if the files are not found on the server, the

TFTP part of the configuration download process ends.

Supported Options for DHCP Servers

DHCP Client supports the following options:

• 001 - subnetmask

• 003 - router ip

• 015 - domain name
