Length:
This field refers to the number of bytes to be configured from the
‘per_packet.txt’ file into PER packet. i.e if this field is given as
‘n’(maximum value of n is 1536bytes), then ‘n’ number of bytes can be
configured from ‘per_packet.txt’ file into PER packet.
Maximum allowed value for this field is 1536bytes.i.e PER packet can be
programmable upto 1536 bytes only.
Sequence number Flag:
This flag is used to enable or disable the sequence number from the
‘per_packet.txt’ file.
If this flag is set as ‘1’ then it will take the sequence number from the
‘per_packet.txt’ file. And each transmitted packet contains same
sequence number without any increment.
If this flag is set as ‘0’ then it ignores the sequence number value from
‘per_packet.txt’ file and sequence number will be incremented starting
from ‘0’.
Default value for this flag is ‘0’.
If the Length filed in ‘transmit_packet’ utility is given as ‘m’ and Packet
length in ‘transmit’ utility is given as ‘n’
Then
1.If m<n then, first ‘m’ bytes can be taken from ‘per_packet.txt’ file into
PER packet and the rest of packet (m-n length) contains default content.
2.If m>n then, ‘n’ bytes can be taken from ‘per_packet.txt’ file into PER
packet and transmitted.
3.If m=n then, ‘m’ bytes can be taken from ‘per_packet.txt’ file into PER
packet and transmitted.
User has to take care while filling per_packet.txt. i.e content should be in
hex format only.
