Cisco Live Barcelona 2018 here i GO!

This is going to be my 2nd Cisco Live, and i’m very excited because i’ve learned a lot over the past 8 years and i’m in a different professional stage at the moment that 8 years ago it was just a dream. I’m a strong believer that these events are important to grow your “networking” and keep you updated on new trends/technology.

So how my calendar looks like so far?

  • CCDE Techtorial and Exam
  • Firepower
  • ISE
  • Multi-Cloud
  • SD-X
  • DevOps

If you are are around, lets grab a beer and crack some of the topics above

ACI anywhere with Virtual Edge (AVE)

The goal of extending ACI anywhere is becoming real with ACI Virtual Edge (EVE), the next generation of the Application Virtual Switch (AVS) for ACI environments. this should be available until the end of the year, AVE is hypervisor independent, offering consistent policy control across multiple hypervisors. For now the only target hypervisor is VMware.

AVS still supported but seems to be time for a change!

No tags for this post.

Don’t let your VMware VCP lapse

A VMware email come through about my VCP, 3 years it’s too short! No way i will let this expire. So what are the options?

(1) Upgrade to VCAP
(2) Update with the latest VCP exam
(3) Certify in a different technology track
At this point i will not move forwards to VCAP, just renew with VCP 6.5. See what’s New on 6.0 and 6.5 and do some labs. After that it’s time to schedule the exam :)

F5 REST API Resources

These are for me the best two resources if you want embrace Dev/Net/Sec Ops using F5 iControl

 

Just a sneak peak of what you can find:

  • Mesos Marathon Container Integration
  • Kubernetes Container Integration
  • RedHat OpenShift Container Integration
  • OpenStack Cloud Integration
  • F5 Application Services Proxy
  • Dockers

Really recommended

SFP validation failed on Nexus

If you come across to an issue like this you are about to fix before that you think. After plug in SFP (1 gig copper) on a SFP+ port i got an error saying “SFP validation failed”.

N3K# sh int e1/45
Ethernet1/45 is down (SFP validation failed)
Dedicated Interface
Hardware: 100/1000/10000/40000 Ethernet, address: 00d7.8fa9.34b4 (bia 00d7.8fa

Last link flapped never
Last clearing of “show interface” counters never

30 seconds output rate 0 bits/sec, 0 packets/sec

So we have to force the interface speed like old days.

N3K(config)# interface Ethernet1/45
N3K(config-if)# speed 1000
N3K(config-if)# no shut

Plugin the cable and done!

Next-Gen SAN reaching 32Gbps

Cisco MDS still evolving as a platform, and Cisco announced technology innovations for next-generation storage networking, giving 32Gb fibre channel performance across a unified MDS storage director and UCS. Cisco storage solutions can help the network adapt to new storage trends such as flash, NVMe, and converged infrastructure workloads.

You can see here the full announcement.
