Description URL Example
Flash path relative to /f10/ash directory
option bootfile-name "flash://FTOS-
SE-8.3.10.1.bin";
##### Conguration le could be given in the following way
FTP URL with IP address
option config-file "ftp://
user:passwd@10.20.4.1//home/user/
S4810-1.conf";
HTTP URL with hostname (requires DNS)
option config-file "http://myserver/
S4810-1.conf";
TFTP URL with IP address
option config-file "tftp://10.10.4.1/
S4810-1.conf";
Flash path relative to /f10/ash directory
option config-file "flash://S4810-1.conf";
If a conguration cannot be downloaded, the following system messages are logged:
00:02:02:%STKUNIT0-M:CP %JUMPSTART-2-JUMPSTART_DOWNLOAD_ERROR: The config file download
failed due to unreachable server ip or invalid URL.
00:02:02:%STKUNIT0-M:CP %JUMPSTART-5-JUMPSTART_RELEASE: DHCP RELEASE sent on Te 0/10.
After 10 minutes of rediscovery attempts, the server IP address is blacklisted as shown in the system log:
00:05:45:%STKUNIT0-M:CP %JUMPSTART-5-JUMPSTART_DISCOVER: DHCP DISCOVER sent on Te 0/
47.
00:05:45:%STKUNIT0-M:CP %JUMPSTART-5-JUMPSTART_DISCOVER: DHCP DISCOVER sent on Ma 0/0.
00:05:45:%STKUNIT0-M:CP %JUMPSTART-5-DHCP_OFFER_REJECTED: Server IP address
10.11.197.39 was previously rejected.
00:05:59:%STKUNIT0-M:CP %JUMPSTART-5-JUMPSTART_DISCOVER: DHCP DISCOVER sent on Te 0/0.
00:05:59:%STKUNIT0-M:CP %JUMPSTART-5-JUMPSTART_DISCOVER: DHCP DISCOVER sent on Te 0/1.
MAC-Based IP Assignment
One way to use BMP mode most eciently is to congure the DHCP server to assign a xed IP address, Dell Networking OS image, and
conguration le based on the switch’s MAC address.
When this is done, the same IP address is assigned to the switch even on repetitive reloads and the same conguration le is retrieved
when using the DNS server or the network-cong le to determine the hostname.
The assigned IP address is only used to retrieve the les from the le server. It is discarded after the les are retrieved.
Following is an example of a conguration of the DHCP server included on the most popular Linux distributions. The dhcpd.conf le shows
assignment of a xed IP address and conguration le based on the MAC address of the switch.
