*Hi Casperians,I have trouble to configure the 10gb ethernet to work on
roach2. The 10gb port (sfp+) is connected to a PC where the file system of
roach2 is mounted. I can use the DHCP server to configure the ip of roach2
ppc, but don't know how to configure the ip address (or interface?) of the
10gb port (roach2 ppc is read-only system). 'ifconfig -a' only shows the
ip (192.168.40.63) assigned by DHCP and a local loop. Could any one give me
some instructions of how to make the 10gbe connection work? *
*Some more info for diagnose: The bof file includes a ten_GbE_v2 block.*
*Parameters used for tap_start (python code which is working without
reporting error): *
mac_base = (2<<40) + (2<<32)
fabric_ip = 192*(2**24) + 168*(2**16) + 41*(2**8) +63 #
don't know what this should be?
fabric_port = 60000
dest_ip = 192*(2**24) + 168*(2**16) + 41*(2**8) +1 # the
address of PC
gbe0_name = 'gbe0'
roach.tap_start('gbe0',gbe0_name, mac_base+fabric_ip, fabric_ip,
fabric_port)
*roach.print_10gbe_core_details("%s" %gbe0_name, False, False) prints
following:*
