I got the mac addresses form
enp> test macadd show....it displayed all 4 macs addresses..
in the ixsys*.config file i added these macadd to the ports 0, 1, 2,
3...
( i havent modified the route* file, like some had suggested to at the
GW, show
I? ) ...
did ./ixstart ixsys*.config....
ifconfig ..
for the l3 sample displays all 4 interfaces
for the count sample displays none of th interfaces ?
in both cases when i try pinging the port from another machine directly
connected by a crossover, it says network unreachable... any ideas??
when i did a tcpdump on the external machine it hung and now refuses to
reboot?
can i connect the port to a LAN through a straight cable and be able to
notice
activity??
thanx,
vikram
