Any Cisco switch/IOS Gurus here?

[omslaw]

OK, so I thought I'd rant a little...but then I guess this could turn in to a shameless attempt at getting some assistance

so...


My infrastructure is mostly 3Com....which I know VERY well.

I have this new Cisco Intelligent Gigabit Ethernet Switch Module for my IBM BladeCenter that I'm trying to get setup so it will talk to my 3Com gear...but I'm having no luck!

I'm familiar with IOS routers...but not the switches. The switch has IOS 12.1(22) on it..


Anyone know enough to help me out?


Thanks!

I'm not a routing/switch guy but I work at Cisco

Whats the issue, maybe I can search some internal pages for ya or some that you dont have access to on cisco.com (cuz I have pretty much full access)

 

[omslaw]

OK, some background...

My IBM BladeCenter supports 14 Blade Servers. These servers will need to be on different VLANs, ranging from VLAN 1 - VLAN 14.

The Cisco Intelligent Gig Ethernet Switch Module (CIGESM) for the BladeCenter has 14 INTERNAL ports (Gi0/1 - Gi0/14...one for each blade), 2 management ports (Gi0/15, 16) and 4 EXTERNAL ports (Gi0/17 - Gi0/20) for connection to 'the network'.

Since my blades will need access to different VLANs, I've setup the connected port on my 3Com 3870, 48-port Gig switch, to be a TAGGED member of all 14 VLANs.

On the CIGESM, I need port Gi0/17 to be a TAGGED member of all VLANs...and then I need to be able to assign the internal ports to a specific VLAN. ...now that I think about it, I may also need a couple of the internal ports to also be a tagged member of all VLANs because I'm going to let the OS determine the VLAN membership.

Again, I can do this...and I *AM* doing it today on my 3Com gear...I just don't know the IOS commands to make it happen on the CIGESM.


Does this make sense?

Thanks for your help!

geeepers. am I a nerd now?

Well, I'm not gonna go there, Greg!

But seriously, thanks for the links. That IBM Technote will help me once I have the switch *talking* on the network

 

[zukracer]

heres what I got from one of the switching dudes:

he should be able to go into enable mode
*at the prompt type enable and give the pw*

Then he would want to do the "set VLAN"

example: set VLAN 10 2/1-10

hope that helps, let me know if not.

 

[omslaw]

Hmmm. I appreciate the advice, but 'set vlan...' is a CatOS command. My switch is running IOS.

I get an error if I try the 'set vlan...' % Unrecognized command

 

[zukracer]

ok, goin back to the switch dude

 

[zukracer]

ok, here's the best I've found so far for ya, not sure if you have this or not cisco install guide

 

[omslaw]

Is that a Cisco Internal site? I can't get to it (error attached). Any way you could send me the PDF? omslaw@gmail.com

BTW, I've made a lot of progress (perhaps this doc will help?)

I now have traffic flowing over all VLANs EXCEPT VLAN 1. I can't get to anything on VLAN 1...which is where most of my servers are...

I really appreciate your help, Brian!

 

[zukracer]

its on the way

 

[omslaw]

Thanks, I'll take a look at it!


BTW, what's the 'Garage Door Opener Mod' that you have listed in your sig?

 

[zukracer]

I put the pics up somewhere on here once, basically just took a remote control for garage door and tap into the control button with a wire to a momentary switch, put the switch somewhere you can reach it and you have instant bat cave control

 

[omslaw]

Ahhhh. Me likey! I have an extra opener...I'll hafta do that! Thanks!

 

[zukracer]

how'd that doc help? any?

 

[omslaw]

Yes, it did. Thanks, Brian!

I've got all but one VLAN working...but I think I have a workaround for that.

I really appreciate your help!

....Man this site's great! Not only can we discuss the Best Bike around...but one can also get Networking issues resolved!

np, always glad to help out where I can

depends on your service contract but you can always shoot the tac an email and they can help you with the remaining issue

 

[TruWrecks]

You need to change the port type to a 'trunk port' so it will do the VLAN tagging as it sends data out. Try something like this:

configure terminal

interface vlan 1
ip address x.x.x.x

interface vlan 2
ip address x.x.x.x

and so on...

interface FastEthernet0/1
no switchport access vlan
switchport mode trunk
switchport trunk allowed vlan 1,2,3,4,...
exit

That will set the port to send all VLAN traffic to the 3Com.

I hope that helps.

Oh great! Did I just hit "Computer Geek" status?

At least I a "Fast Computer Geek"!
