Hi,
How can I do to create and use priority queues for packets with DSCP
field marked on Iron Core devices ?
The command qos-tos on "ve" is enough ?
Thanks a lot
Giuliano

Yes. The ServerIrons need to measure the RTT between the real servers
an the clients, so you need a ServerIron in the path between every
server and client, preferably very close to the servers. Hard to
imagine how to do this without having a ServerIron at each location.
But why not? It's a great SLB box anyway.

In theory. I practice they can only handle A records, and they will
not respond at all to requests for anything else (at least they didn't
with 07.1.21 and earlier SW)! This means that you *must* have a real
DNS server behind the ServerIron to serve NXDOMAIN answers to e.g.
AAAA requests, or clients supporting IPv6 will suffer a long delay
caused by DNS timeout.
