Cisco OnePK Topology

OnePK-AllInOne-Topology
In my last post, I showed you how to get Cisco's free OnePK all-in-one VM to run inside Parallels for your testing.  I needed an easy-to-read topology map for quick reference as I do my tests.  The topology map that Cisco put in their documentation is less than ideal.  Below is my diagram.  Some quick notes: The brown ethernet segment (10.10.10.0/24) is the VM Guest segment.  This allows you to access the routers from within the VM using the static IP's assigned to the interfaces. The red ethernet segment (ETH1 / DHCP) is a DHCP-based segment for the VM Host.  This allow you to access th...

Cisco OnePK VM in Parallels

cisco-onepk-logo
Over the last couple of weeks, I've been bit by the "Automation Bug".  I want to automate everything.  Why?  Well, there are two reasons why I want to automate everything I can: Remove tedious, mundane, and repetitive tasks.  If I can do the same task over and over again, not only do I save time, but I remove any human errors from the equation. Abstract the complexities of the tasks at hand.  This is very useful when delegating the tasks to personnel who may not fully understand or know the intricacies of the steps. This week, I've started to learn about Cisco's OnePK software develop...

Intelligent Management Center Tacacs Fails to Authenticate

We all have our preference over AAA protocols. The most popular being RADIUS, with TACACS+ having a following only due to historical momentum of the company using it. DIAMETER is slowly coming to the market due to it’s more ‘enhanced’ capabilities, but it’s hard to change from “what works”. And TACACS+, my friends, just works. I won’t go into detail on why I love that protocol, but instead, tell you about what I learned today. Why move away from tac_plus? For years, I’ve been using the tac_plus daemon to do all of my AAA (Authentication/Authorization/Accounting) needs. It’s free, it’s so...

UCCX Scripting – Iterating Different Recordings

When scripting UCCX call center queues, it's common to put a caller on hold for a defined period of time, then do something with them.  Then, put them on hold again.  This could be to hear a "Thanks for holding.  We'll get with you shortly" every 2-3 minutes with hold music in between. Basic For example, here, you will see a basic call loop.  A call gets queued if the resource (call center queue) is not available.  I created a variable called "CallQueueHoldDelay".  This is set to 90.  Which means, the call is put on hold (hears hold music), waits 90 sec...

Getting user-mode after logging in with aaa user at privilege 15

Had an interesting issue today.  I enabled AAA Authentication on a used Cisco 3560 switch.  I then created a user with privilege 15.  But, every time I used either telnet or SSH, I was always getting User Mode.  I wanted Priveleged Mode. Since the highest level of privilege commands is 15, I should be getting full permissions if my user is ALSO set at privilege 15, right?  Well, it does, but first there was a tiny configuration that needs to happen.  First, let's enable AAA on the device: big-old-switch(config)# aaa new-model Now, let's create a user: big...

Collecting Cisco ASA VPN Tunnels on HP IMC

Just got asked the question on how I collected and graphed the number of active IPSec VPN Tunnels on my Cisco ASA with the HP IMC (Intelligent Management Center).  The OID I am collecting on is the number of active Phase1 IKE Tunnels:  .1.3.6.1.4.1.9.9.171.1.2.1.1.0 Here is a screenshot of my Performance Index that I'm collecting:   After that, click the TEST button at the bottom of the screen.  Type the IP Address of the ASA that you want to collect from and choose "Resolve". Once it resolves, you should see the instance populate from the data you input from...

IP Communicator dropping Contact Center Calls

There are always “gotchas” when working with Cisco Unified Communications systems, and they are not always obvious. UCCX (Contact Center) is no exception. PROBLEM: A VPN Call Center Agent receives a call from the Contact Center. Upon answering the call, it either just drops with dead air, or the agent hears a fast busy. ENVIRONMENT: The Agent uses IP Communicator to answer calls over the VPN. First, let’s find out what does work: Testing and troubleshooting took a total of 10 hours. I looked at the gateway, the agent settings, Contact Center, etc. All looks normal, and operati...

Surprise – Cannot access Cisco IMC

I had a Cisco UC upgrade project recently completed.  The move from UC 5.x to 8.x left me with a decision... do I keep with the old MCS hardware (of which are Proliants, which I love), or move to the new Cisco UCS systems. Well, being a techno-geek, I couldn't pass up learning something new.  And with the full backing of Cisco support, you can't go wrong. Today, we had an environmental failure, and the VM's on the UCS box would not start up.  Strange.  Being I'm in the server room, I access a server console, and browse to the CIMC (Cisco Integrated Management Controll...

Cisco – ip default-route VS ip route

ip default-route vs ip route Ran into a small problem yesterday, where a sub-contractor dispatched a technician to provision a new DSL line (on a Cisco 851) for me at one of our retail stores. It really was not a huge change. Mostly, just changing the ip address and default route. After 3 hours, the technician calls me back saying it’s not working, and if I gave him the right information. Not arguing, seeing as how I can screw-up a mechanical pencil, I check my information, and all seems right. I webex into his laptop, and requested him to console to the router. After doing a &ls...

Is Cisco Losing in Switching/Routing?

I'll start off by saying, I'm not an analyst.  I'm not going to quote or link you to analytical articles or mention Gartner's Quadrants (oh crap, I just did!).  What I am going to write about, is my personal opinions on where Cisco is going with their data networking in the enterprise, and why.  I do make many generalizations in this post, so please comment on your thoughts. First off, 4 years ago, Cisco was number 1 in any kind of enterprise switching and routing market (for the most part).  Even though there were other vendors in the industry, you boug...
