Brocade ICX7750s

Very powerful 7750s went in to replace two core SuperXs.  I went in to the customer with a local partner. He did almost all the work and did very well. This project was a success.

Brocade VDX: Three Important Commands For Verifying The Fabric

You got three good commands for verifying the fabric.  Here they are in action:

Notice the link interfaces in the command below.
VDX1# show fabric trunk

Rbridge-id: 1

Trunk    Src      Source         Nbr        Nbr
Group   Index   Interface       Index   Interface               Nbr-WWN
-------------------------------------------------------------------------------
 1      64      Te 1/0/1        64      Te 2/0/1        10:00:C4:F5:7C:58:F2:3C
 1      65      Te 1/0/2        65      Te 2/0/2        10:00:C4:F5:7C:58:F2:3C
 1      66      Te 1/0/3        66      Te 2/0/3        10:00:C4:F5:7C:58:F2:3C
 1      67      Te 1/0/4        67      Te 2/0/4        10:00:C4:F5:7C:58:F2:3C


Notice the bandwidth and the primary interface of the ISL link.
VDX1# show fabric isl

Rbridge-id: 1   #ISLs: 1

 Src       Src           Nbr       Nbr
Index   Interface       Index   Interface               Nbr-WWN           BW   Trunk  Nbr-Name

Notice the mode we are operating in, along with the VDX MACs, IPs, and status.

What Is A Mellanox Adaptor?

In some cases, you might need a "Mellanox" adaptor. It's a 40gig QSFP to 10gig SFP+ adaptor.  In some cases, it's very useful.

An Early Sunday Thought For Both Sides Of The Racial Ilse

No matter who we are or what color God made you to be, let us remember what God said through the apostle Paul. If you dispute this, then you need to have a talk with God.

Brocade Datacenter VDX 6740 Install

I did a Brocade VDX install last week of two 6740s in a small data center. This was to get the initial install in place and get them up and running on the new gear.  Phase II will be to hook into VMWare and connect a few other physical servers in. Currently the SANs and VM environment is in place and the customer said they notice a difference in performance already. I'm very happy to hear that.  Notice below, I have 20 gig to form the VCS fabric (although I added two more for 40 gig after this picture).

Brocade VDX: What Is A Breakout Cable And How To Configure For It?

It's not as hard to grasp once you see it. It's a 1 QSFP to 4 SFP+ (40gig to 10gig).  Notice the larger 40 gig side on the left, and the four 10 gig on the right.

VDX1(config)# interface FortyGigabitEthernet 1/0/50
VDX1(conf-if-fo-1/0/50)# shut
VDX1(conf-if-fo-1/0/50)# exit
VDX1(config)# interface FortyGigabitEthernet 2/0/50
VDX1(conf-if-fo-2/0/50)# shut
VDX1(conf-if-fo-2/0/50)# exit
VDX1(config)# hardware
VDX1(config-hardware)# connector 1/0/50

Home Projects: Installing IKEA Cabinets

This wasn't too bad, but getting that back rail that keeps everything lined up correctly and level is the whole key. And oddly, took the most time.


I'll put up a finished kitchen picture when it's all said and done when I actually get it all finished.

Home Projects: Building IKEA Cabinets

For the '35 house, we are redoing the kitchen as well. We have mostly built the cabinets and are ready to put them in.

Home Projects: Installing A Dryer Vent

Just to get that title straight, where I'm from, we say that like "dri'r". That's one consonant.
Anyway, in that old '35 house, there was no dryer vent in the new laundry room (which was an add on to this house at one time. So, I added one. Below are some pictures of what I did. I used a saws-all, a drill, and jig saw.

Brocade Network Advisor: Need To See The Front Panel, But Dont Have Physical Access?

I know I have had several BNA posts here lately, but it is a pretty cool tool.  Ill plan on having more in see future as well.  One quick thing here.  If you need to see the front of the box for some reason, just go into BNA and it will show you for any gear you have loaded in. I know most other vendors do this as well, but still pretty cool.
Notice below, I have a CAT5 patch cable in port 1/1/35 (designated just like you would see as if you were looking at it).

Brocade Network Advisor: Can Not Backup Configuration Of Switches

BNA is a really good tool for the network engineer to have.  And its a fraction of the cost of something like SolarWinds.  There are a few things to do when trying to get backups of the config, but one thing in particular I ran into recently is that you DO have to create a crypto key.

L3_Switch(config)#crypto key gen rsa mod 1024
L3_Switch(config)#
Creating RSA key pair, please wait...

RSA Key pair is successfully created

I kept getting a failed notification for one switch in particular.  I retyped in the logging host IP, community strings and even my username.  But when I put in the command  up above to create the crypto key, it was then successful in doing the backup from BNA.  Its one option should you have issues.
In case you wonder, from the switch perspective, this is what it sees:
00 days 05h15m21s:I:Security: SSH logout by shane from src IP 10.10.10.1 from src MAC f8ca.b855.7e7c from USER EXEC mode using RSA as Server Host Key.
00 days 05h15m21s:I:SCP transfer from device completed
00 days 05h15m20s:I:scp -f runConfig
00 days 05h15m20s:I:Security: SSH login by shane from src IP 10.10.10.1 from src MAC f8ca.b855.7e7c to USER EXEC mode using RSA as Server Host Key.

This Is Very Concerning For The USA

This concerns me. We have seen what happens too many times elsewhere when the national debt gets too high.
