DHCP Retry Mechanism
BMP can request different DHCP offers
BMP requests a different DHCP offer in the following scenarios:
• If you enter the reload-type jump-start config-download enable command, the DHCP offer
specifies both the boot image and the configuration file.
• If either the image or the configuration download is successful, BMP does not request another
DHCP offer.
• If the image download is successful but the configuration download fails, the switch boots up with
the default configuration.
• If the image download fails, the switch does not try to download the configuration file and starts
sending requests for a new DHCP offer from a different server. The previously offered server is
blacklisted.
• If the offer contains only a boot image that cannot be downloaded, BMP requests another DHCP offer.
• If you enable the reload-type config-download command and the configuration file in the offer
cannot be downloaded, the switch boots up and loads the startup configuration stored in local flash
memory.
DHCP Server IP Blacklist
If the process does not complete successfully, the DHCP server IP is blacklisted and the DHCP process is re-
initiated. A DHCP server is maintained in the blacklist for ten minutes. If a DHCP offer is received from the
blacklisted DHCP server, the offer is rejected.
File Server
Set up a file server and ensure connectivity.
You must configure the server that holds the boot and configuration files as the network source for the
switch. The switch recognizes HTTP, TFTP, FTP, and Flash URLs.
For example:
• tftp://serverip/filename
• tftp://hostname/filename
• ftp://user:passwd@serverip//mypath/filename
