Just a quick note about a problem I ran into with adding data groups to an F5 system using tmsh. I wanted to add a string data group containing a list of URIs mapping to other URIs. This was for use in an iRule that will redirect these URIs.
So I thought that this tmsh script would do the trick:
modify ltm data-group redir_uris records add {"/first-uri" { data "/new-uri"}} modify ltm data-group redir_uris records add {"/second-uri" { data "/new-uri"}}
Every time I tried it, I got this result:
Syntax Error: the "create" command does not accept wildcard configuration identifiers
Hmm. But I don’t have any wildcards. So what’s the problem? I couldn’t figure it out at the time, and ended up having to resort to manually entering the data group via the web interface. A bit slow, but luckily it was only around 20 entries.
Today I found out what was going wrong: SOL12999: “Data group records beginning with a slash character cannot be added using tmsh.”
Description: You cannot add data group records that begin with a slash ( / ) character to data groups using tmsh.
This issue occurs when all of the following conditions are met:
- You Continue reading
A few months ago Gigamon did the right thing: they figured out that their true value lies not in the hardware boxes, but in the software running on them, and decided to start offering their GigaVUE-OS on whitebox switches.
So far, Arista is the only other networking vendor that figured out it doesn't make sense to resist the tide - Arista EOS is now available on Open Compute Networking whitebox switches.
Update 2015-04-02: If you followed the links in this blog post, you probably figured out that it’s an April Fools’ one. However, that’s not the end of the story…
Read more ...Life is about moving from one journey to the next. Today marks exactly one of those changes. Cisco announced their intent to acquire Embrane, which takes us to the next phase in our journey.
It’s been five exciting years since Marco and I founded Embrane. So many great memories come to mind – but I am even more excited about what we have in front of us.
Joining Cisco gives us the opportunity to continue our journey and participate in one of the most significant shifts in the history of networking: leading the industry to better serve application needs through integrated software-hardware models.
At Embrane, we have demonstrated the ability to build products that accelerate the adoption of more agile models for virtualization and automation of networking capabilities in the data center.
The networking DNA of Cisco and Embrane together drives our common vision for an Application Centric Infrastructure. We both believe that innovation must be evolutionary and enable IT organizations to transition to their future state on their own terms – and with their own timelines. It’s about coexistence of hardware with software and of new with legacy in a way that Continue reading

Day after day, an employee uses legitimate credentials to access corporate systems, from a company office, during business hours. The system remains secure. But suddenly the same credentials are used after midnight to connect to a database server and run queries that this user has never performed before. Is the system still secure?
Maybe it is. Database administrators have to do maintenance, after all, and maintenance is generally performed after hours. It could be that certain maintenance operations require the execution of new queries. But maybe it isn’t. The user’s credentials could have been compromised and are being used to commit a data breach.

After having a nice conversation with Josh Williams (@JSW_EdTech) and helping Eddie Forero (@HeyEddie) with some E-Rate issues, I’ve decided that I’m glad I don’t have to deal with it any longer. But my conversation with Josh revealed something that I wasn’t aware of with regards to the new mandate from the president that E-Rate needs to address wireless in schools.
The first exciting thing in the new rules for E-Rate modernization is that there has been an additional $1 billion injected into the Category 2 (Priority 2) items. The idea is that this additional funding can be used for purchasing wireless equipment as outlined in the above initiative. I’ve said before that E-Rate needed an overhaul to fix some of the issues with reduced funding in competition for the available funding pool. That this additional funding came through things like sunsetting VoIP funding is a bit irritating, but sometimes these things can’t be helped.
The second item that caught my attention is the new budgeting rules for Category 2 in E-Rate going forward. Now, schools are allocated $150 per student for a rolling five year period. That means the old “2 Continue reading
In an interview with Infinera's VP of Marketing Michael Capuano, we learn more about the Open Transport Switch (OTS) and how it's helping companies like Pacnet virtualize the optical layer.

Application integration has often been an exercise in frustration – long delays, high costs and over promises by vendors. How many ERP projects have you heard of that were canceled or shelved due to complex customization and integration challenges?
Integration though, is coming to a new place. Cloud technologies and open APIs are helping enterprises merge on-premise and off-premise systems without considerable coding and re-architecting. Instead of requiring specialists in SOA, enterprise service bus (ESB), extract transform and load (ETL) and data warehousing, organizations are hoping the concept of Integration Platform as a Service (iPaaS) can be used to integrate systems in half the time using technically-savvy generalists and increased involvement from lines of business.
