SPAN

Found a great comprehensive tutorial on SPAN for switches. Maczen, I'll bet you'll love this.


By the way, Billy and Gene, I was watching this Star Wars deal (I remember the first one in what...1977? Saw it in the theater)---these out of order episodes...something about this east side gang called the Sith Dogs or something, and these dudes were sword fighting with light toy swords, and the planet was melting in a pool of lava, and the one good guy jumps to safety, and the evil dude catches on fire and gets all deformed, and this Chancellor dude saves him...the evil dude turns into Robo Gang Leader, and they call him Darth Vader (I remember him). Now I REALLY wonder about you guys, and your fascination with this...lol

I am grateful for Cisco. Happy friggin' Turkey Day!

Awesome tutorial! They forgot to mention that this doesn't work with PVLANs so I thought that I would mention it here! No IGMP snooping! I will play with this sometime this weekend!

Burt, I wish they would have made a TV series with that concept! The only thing I had to watch was a never-ending series about these space police in tights! They patrolled the universe boldly going where no man had gone before and usually hauled @$$ back out of there! LoL

I would have loved to see them beam down to a planet, just once, and butt heads with one of those Jedi dudes from the movies you were talking about.. Can you picture it? "Set phasers to stun! Fire!.... Fire, Fire.. Oh $&*#! Beam us up, BEAM US UP!!!" LoL

Happy Thanksgiving Everyone! Even the Trekkies! LoL

And you know, only the guys in the gold and blue tights would survive. The one's in red are bantha fodder.
 
All I have to say is that if you have kids, thank goodness for the triptophan...

Dalt,
They could not have paid me to wear a red suit and be a part of a scouting party! LoL

Buirt,
(This is from Wikipedia but apparently many believe that is it is high amount of carbs that cause drowsiness and not the tryptophan!)

"One widely-held belief is that heavy consumption of turkey meat (as for example in a Thanksgiving or Christmas feast) results in drowsiness, which has been attributed to high levels of tryptophan contained in turkey.[47][48][49] While turkey does contain high levels of tryptophan, the amount is comparable to that contained in most other meats.[14] Furthermore, postprandial Thanksgiving sedation may have more to do with what is consumed along with the turkey, in particular carbohydrates and alcohol, rather than the turkey itself. This is demonstrated in an episode of the sitcom Seinfeld when characters drug a woman using turkey and alcohol in order to play with her toy collection."

At least I am assuming that it's the carbs and not the alcohol.. LoL

Or is a Tryptophan some sort of Trekkie gadget? LoL

Leave it to you to Google "triptophan"...lol
I ate about a handful of turkey at my mom's because we had to go to my brother-in-law's house afterwards. I don't drink much (like 1-2 times a year, maybe, some years not at all), and so I did not drink on Thanksgiving. I was very tired 1/2 hour later. I take 5-HTP (5-hydroxytriptophan) supplements now and then for sleep, so that is what the purpose is. I know turkey has a lot more triptophan than any other meat, too.
As far as the trekkie thang...I'm no trekkie, but I'd rather see those trekkie chicks any day of the week over some 7'9" gal with a green oblong forehead, three noses and 17 toes on each foot. Noses on the face, not foot...lol

Burt
 
LoL.. Star Trek has alien chicks too but I am not going to start a "Who's got the hottest girls, Star Trek or Star Wars!!!" LoL Would never live that one down!

I admit that I did Google tryptophan! Initially thought it was some trekkie gizmo!

Weird...it was the other day...

That's nothing Burt...now today the site is getting blocked for me at work by our content filtering.

I've got a good one too with some monitoring. We have DS3's as our uplinks back to our corporate data centers. Recently we implemented some IPS devices and setup a VRF instance to route anything destined for the data center to route out a fiber interface, to the IPS, back into another fiber interface on the same router, then out the DS3. I can now span a port and see the traffic going across my DS3's. It's pretty cool how it's all working, but the VRF stuff is kinda goofy how you have to think about any show commands.
 
Dalt,
Why wouldn't they go:

Traffic-->Router-->IPS-->DS3

Instead of:

Traffic-->Router-->-|
DS3<--Router<--IPS<-|

It seems as if they are overworking the router! This is probably a newbie question by the way! LoL

The IPS doesn't have a ds3 interface so it has to get "converted".
 
OIC! Thanks!

Dalt,
You have any good links on DS3? Looks like I can get an ATM DS3 card for around $100. But will need a 72xx series router (non-VXR is fine) so just wanted to check and see if this would provide the same benefit for study as modern implementations (I know that you have a fiber setup etc.)

B Haines

I don't have anything good on DS3 really. That's a good price on a card...the router on the other hand is probably going to be steep. There's a lot to the 7200 to have just for it to work.

 
btw, I'm personally not a big fan of the 7200. Ran into some bigger limitations on the ones I had at work. Was pretty excited to get rid of them and move to flexwan cards in my 6500's for the ds3 and t1 interfaces. Only problem I have with the flexwan is the 6500 doesn't want to do traffic shaping. Will police the traffic, just not shape.

The 7200, we kept running into bandwidth point limitations. Basically, each side has so many points for bandwidth, and depending on the card you used on that side, it used x amount of points. Then either my npe or the i/o controller needed a memory upgrade and the places I all talked to told me that for what we had, it would actually be cheaper to buy a different npe or i/o controller (I can't remember which it was) than to try and find the memory for what I had.

I shouldn't knock the 7200, it did work great for several years, but then once the network really started to grow again, it was starting to not cut it anymore.

 
Was that a VXR model?

B Haines

both vxr and non vxr actually
 
I see! Thanks for the heads up!
