Description URL Example
Flash path relative to /f10/ash directory
option bootfile-name "flash://FTOS-
SE-8.3.10.1.bin";
##### Conguration 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 conguration 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 eciently is to congure the DHCP server to assign a xed IP address, Dell Networking OS image, and
conguration 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 conguration le is retrieved
when using the DNS server or the network-cong 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 conguration of the DHCP server included on the most popular Linux distributions. The dhcpd.conf le shows
assignment of a xed IP address and conguration le based on the MAC address of the switch.
