Stutch.
Ok, is there a quick way for me to allow access via SSH and web to access the Core on its public side?  That will give me a quick way to grab the config for you.

Easiest way. Browse to webadmin.
Under configuration|network you can enable/disable the internal firewall.
Thats the easiest way to activate access on public side.

Beware if your public side is directly attached to your DSL/internet router.
If it is not then I guess your internet router have a firewall configured.

there is also some options to open up just some ports on this page.

 switchport mode access (This tells the switch the a computer is attached to this port, vs another switch or router.)

not exactly. This tells the switch to not use 802.11q

Quote
bandwidth 10000000 (This manually sets the port to allow the use of maximum bandwith.)
wrong. This does not affect the bandwith of the port but adjust metrics for routing protocols.

Quote
spanning-tree portfast (this is essential for PXE clients as it disables the 45 second port diagnostic and spanning tree checks that each port typically goes through when a new device comes on line.)
this has nothing to do with port diagnostics. Btw, the default settings for spanning tree are 50second (2x15s+20s).

from my point of view the switch config looks fine. Any results from the port counters?

best regards,
Hari

you have your bandwidth set to 10Mb...?
No. Bandwidth = (10000000/raw bandwidth measured in Kb/s)

When I attempted to disable the firewall I got an ugly web error on the system.  I'm going to reload it and see if I Can get around that problem.  after that, I will post for you what I see.

Better to just only open port 22 for ssh, and everything else can be tunneled using ssh.

As hari says, there is not much to go wrong with the config.
 I would however recommend (sorry for sounding like a besserwisser/messerschmidt or whatever) to use Auto(speed,dup) on all the active ports. I have not seen the Cisco devices having the jumping link problem anymore.

If you want spanning tree to be faster, start using Rstp instead or even Mstp. The convergence times will be much faster..
For bandwith, you have already set it to 1000. If you want to control bandwith you do it with Qos policing  :P NOT Recommended however... (have seen major issues/bugs using that on several C devices(7204,7609,3550) in previous ios 12.2 releases, probarbly corrected now but I would not give it a try just because if the history.

Now show us the fresh 'sh int'  i.e. clear the interfaces and don't mess with the cables then let run for quite a while watching movies. and some wireshark results would be nice as well =)

It was raw paranoia that caused me to force the speed & duplex setting as well as the other settings on the switch to begin with.  I’ve been screwing with this issue for months; following numerous threads in this forum that I had hoped would help me to resolve my issue.   I should not need an enterprise class switch to stream movies… and yet, here I am. (Not complaining!)

Furthermore, I won’t need to mess around with QoS as this switch is dedicated to just the internal media network.  ;D
I will take your suggestion and reset the port settings for  speed and duplex.   This was just another example of me needing to verify that I was getting the speed that I was expecting.  I had already discovered cat5  patch cables that were not rated for gig speeds causing me headaches.

So for the sh int, do you need me to grab this a few times while a movie is running?  Do you just need it off the core, or the media device as well.  I’ll do sniffing as well.
I appreciate the assistance from all of you. 

You are all on the Christmas list now.

haha, paranoia is good  ;D

Don't forget to update the Core and MD with the same settings(speed, dup) though

sh int afterwards is fine. for both of the interfaces. Lots of Runts and drops are not good.
Take a quick look in the syslog as well just to make sure(that all is ok with the 3550).

Not sure how to do a similar in linux though =/ but that will give some hints if this is related to the network which I actually doubt.

(hari posted some nice commands to be run as well)

Btw, I assume you have everything on the inside of the Core, as recommended ?

Is it easy for you to move(copy) the same Movie to the hdd of the Core and view it from there as well?

Just to easily eliminate eventual troublecausers.
Also I posted a while ago about twitchy playback and got the recommendation to not use alpha blending.. Try changing that.(in case you are)

Good Luck!

I will reset all ports on the 3550 to the default configuration as suggested, but I'll leave the portfast enabled on the client ports.

I plan to reload the server again tonight and try both Hari, and your suggestions.

If you are referring to media directors and all that stuff being on the correct side of the core, then yes.  I have followed all recommendations as closely as possible on my configuration.

All my movies exist on the core.  I use the media directors as well as the core itself to rip movies.  I guess I am not sure what you mean?

I was a passionate viewer of that thread! :) as I had hoped that it would also uncover my issue. Immediately after it was suggested, I had turned off the alpha blending, but did not see any improvement.  I cried a little inside. :'(

yes, it should. Replug the cable (or shut/unshut the switchport) and see if autoneg works. Worst case you have to use fixed settings (Use "ethtool -s ethX speed 1000 duplex full" on the linux side and revert to the old duplex/speed settings on the switchport)

Please show me the ifconfig output of the NICs on the linux hosts.

On the core, issue a:

sudo -i

and then just

ssh moon##

to the MD... Get the Media Director's number from the web admin...
