Need another SRX

Looks like the EX2200's don't have the layer 3 capabilities I'd need to have it be set up with provider bridging functions. I wasn't sure, but now know.

So... I'll be needing to pick up another SRX sooner than later, as the SRX does.

Need to be able to run this configuration to emulate the MX commands:

user@beb1> show configurationrouting-instances {pbn-1-for-eline {instance-type virtual-switch;interface ge-2/0/0.1;interface pip0.0;bridge-domains {bd1 {vlan-id 10;}eline-svlans {vlan-id-list [ 2100 ];}}pbb-options {peer-instance pbbn-1;}service-groups {eline1 {service-type eline;pbb-service-options {isid 10100 interface ge-2/0/0.1;}}}}}

Carrier Ethernet topology a bit more set

Gotta luv local liquidation companies...

The Haul yesterday:

2950g EI
Dell powerconnect 3024 (new in box)
Cyberpower 1350 AVR UPS

All for cheap...

With the Cyberpower setup protecting my Main PC(Core i5 680, Nvidia GTX560Ti), the Network rack PC(Core2Duo 2.4ghz, Nvidia 7950Gt), and three 23" monitors, and a few peripherals, it's running 235watts. or 29% of the Cyberpower's capacity.

I have always wanted one with the LCD diplaying output. Not bad for $21.00. I think they run $150.00 new. We'll see how long the batteries last. The are charging to 80% and are showing at 235watt output to have 12 minutes of up time.

Even if it dies, Used UPS are almost always a good deal, as you can run down to a battery store and pick up new replacements for around $40.00, or even cheaper online. For $60.00, I could essentially have a new $150.00 UPS.

First week of Introduction to Python Programming complete

The assignment submission familiarization week is over, and we get on to our first real project:

Rock, Paper, Scissors:

In our first mini-project, we will build a Python function rpsls(name) that takes as input the string name, which is one of "rock""paper""scissors""lizard", or "Spock". The function then simulates playing a round of Rock-paper-scissors-lizard-Spock by generating its own random choice from these alternatives and then determining the winner using a simple rule that we will next describe.
While Rock-paper-scissor-lizard-Spock has a set of ten rules that logically determine who wins a round of RPSLS, coding up these rules would require a large number (5x5=25) of if/elif/else clauses in your mini-project code. A simpler method for determining the winner is to assign each of the five choices a number:
  • 0 — rock
  • 1 — Spock
  • 2 — paper
  • 3 — lizard
  • 4 — scissors

SFP interchangeability

Well, the ADVA 850mm SFP's that apparently weren't compatible with the Cisco 3560,

DO WORK in a Juniper EX2200. This is a HUGE savings, as I picked up 6 ADVA SFP's for $35.00, and the cheapest Juniper compatible SFP's I could find were $45.00 a piece.

root@Juniper# run show chassis pic pic-slot 1 fpc-slot 0
FPC slot 0, PIC slot 1 information:

Obviously, ADVA branded, but actually, a Finisar product...

EX2200 password recovery

Enter configuration mode in the CLI:
user@switch> cli
Set the root password. For example:,
user@switch# set system root-authentication plain-text-password

whoops...Anyway, it's here: and you may need to have a (free) Juniper account set up to get to it. I have a J-TAC account due to work.

Jist of it is, you power the device on, hit the spacebar when you get this prompt:

Hit [Enter] to boot immediately, or space bar for command prompt.

Then, once it gets to this prompt: loader>, you type boot -s, which starts it in single user mode

Then, you will get this prompt:

Enter full path name of shell or 'recovery' for root password recovery or RETURN for /bin/sh: recovery

Then, in my case, it went to a normal, non-configure prompt, where I moved to configure mode, and then set a new system, plain text password:

user@switch# set system root-authentication plain-text-password

Then, obviously, commit and reboot.

EX2200 in the rack...

came last night, but had to get caught up in my Python class. Still need to password restore it.

Pics or it didn't happen...

Carrier Ethernet topology

This is the topology I'll be working with for now. (well, once the EX2200 arrives and the SFP's)

Pressure to complete the CCNP off, back to Python

Having moved into an Engineer position, and work requirements really making Juniper and some Layer 2 technologies being more important for the time being, I'm going to back off the CCNP for a bit, and focus more on my overall Network engineering knowledge and education.

That said, I'm going to give a non-shameless plug again to

I am starting the Rice University "An Introduction to Interactive Programming in Python" again.

right Heah...

Class started Oct 6th, but I believe they may still be taking sign-ups.

One can now pay $49.99 and get a certificate from Rice University stating that you have taken the course.

I believe I could likely have it paid from our training fund at work, so I may do that.

Juniper EX2200 on the way

Barring any of the occasional EBay/Paypal issues, I should have an EX2200 added to the Carrier Ethernet rack within the week possibly. Surely by next week.

I have the devices partially set up now, and am working on an E-line configuration through the SRX210 from the ADVA 825.

Once the EX2200 comes in it will be run (Rack Server)HOST A -(1gig copper)- ADVA825 -(1gig copper)- SRX210 (1gig copper)- EX2200 -(1 gig MM fiber)- ADVA 206v -(1gig fiber)- HOST B(Cisco 3560)
