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!

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
9.34b4)
MTU 1500 bytes, BW 10000000 Kbit, DLY 10 usec
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA
Port mode is trunk
Full-duplex, 10 Gb/s, media type is 1G
Beacon is turned off
Input flow-control is off, output flow-control is off
Rate mode is dedicated
Switchport monitor is off
EtherType is 0x8100
Last link flapped never
Last clearing of “show interface” counters never
0 interface resets
Load-Interval #1: 30 seconds
30 seconds input rate 0 bits/sec, 0 packets/sec
30 seconds output rate 0 bits/sec, 0 packets/sec
Load-Interval #2: 5 minute (300 seconds)
input rate 0 bps, 0 pps; output rate 0 bps, 0 pps

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!

N3K(config-if)# show int e1/45
Ethernet1/45 is down (Link not connected)

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.
