In the example above, the BOOTP request was dropped because the number of seconds elapsed since the
start of the process was not incremented (secs=0), and the forward delay was set to 3 seconds.
We got in a tweaked zero IP address packet on BSD socket shown below:
Recvd on bsd socket pkt from 0.0.0.0, rtr-port addr=20.20.20.200, 0x336860360
Received request packet for the bootp service on bsd socket
hops=0x0
The BOOTP REQ field shows that we haven't waited long enough. (The seconds shown is 0, when it
should be greater than or equal to 3.)
handle_uevent_udprelay_cmm(d): received on
relayDebug
handle_event_ipc_Ludprelay_cmm: num oef bytes received = v368elCMM =-1
handle_event_ni_udprelay_cmm: Recieved message from the NI
handle_event_ni_udprelay_cmm: Recieved message from the NI for regular UDP pack
Finally, the Dshell command bootpSizeCheck turns on/off the bootpSizeCheck function. (By default it is
off.) To turn it on enter the following:
Working: [Kernel]-> bootpSizeCheck = 1
To turn it on enter the following:
Working: [Kernel]-> bootpSixeCheck = 0
Note. OS-6600 supports minimum of 64 byte size packets.
