Hi All,
I have an interesting problem where I have an analogue signal coming in
which is processed by a MUX and encoder; it is a live broadcast system. The
MUX and encoder have resilient Ethernet ports which are patched into two
separate switches both going back to a resilient core. If one of the
switches reboots of fails the system fails over nicely and broadcasting
continues. The problem arises when the switches starts to come back online,
the mux and encoder fail back over as soon as they see a physical link, the
switch isn't ready to process packets for another 3 minutes, as you can
guess we lose the live broadcast and a lot of people get upset. The problem
doesn't occur if we use hubs instead of switches as they are dumb and
process as soon as they become live. Is they anyway of delaying the switch
Ethernet port until it is ready to process packets, i don't really want to
use hubs as this limits my monitoring options.
Many Thanks,
Wayne
