I am replaying too late . But just to add little more
..
We have 4 brocade switch ( on each fabrics ) ISL'd
together . 1 32 port main brocade and 3 HP Blade
minuture switchs ( 8 port ) .
ISL between brocade very simple ( as you already found
out ) by just connecting the fibre cable between
switches . Few points you need to make sure before
you connect the cable .
1. There should not be any zone config on new switch
you are adding . if any , remove it before you
connect the cable . ( if might work if there is some
zones , but you wil end up cleaning it and if for any
chance , wwn or fcid confcit with new and old , it
will affect your prod )
2. dom ID should be uniq . Easy way to do this is
keep all Blade switches above 20 .
3. update firmware on new switch to min what is on the
main switch.
I worked on brocade for 5 + years but I like the
cisco mds now because it has some cool featurs which
brocade does not have . We are going to get HP
Blades with Cisco switches now onwards . One cool
thing with Cisco - cisco ISL ( both switch should be
Cisco) is that if you saturate the san traffic ( with
blades it is possible ) all you need is to coonect one
more cable between these switches and cisco
automatically truck it to double the bandwidth .
Thanks

Thanks to Todd Willeat, and Richard Aranas:
Yes it is that simple. Just make sure your Firmware
levels are up to
date, Run a cable between the switches, and they act
like one switch.
Just keep an eye on: Domain ID, they must be
different on each switch in
an ISL, and which switch is Principal, and which is
Subordinate.

Subject: [HPADM] OT: Cascade Brocade Switches
List -
Sorry for the OT post, but this list is so good, I
had to give
it a try.
Ok... enough sucking up...
Has anyone cascaded two fiber channel switches
together? We have
a 32 port brocade, and want to cascade it to another
brocade. In essence
we want to "add" ports to a 32 port switch. All of
the info I've found
is in relation to trunking switches. That's not what
we want to do, we
want to ISL them. I want to take 1 port on the 32b,
and connect it to 1
port on an HP P-class internal switch, in an HP
Blade enclosure. The
blade enclosure switches have 8 internal ports, and
4 external. I've
heard that all I need to do is connect a cable from
one switch to the
other switch, and viola, ISL'd. Sounds too simple.
Any help appreciated.
Galen
