Enable Jumbo Frame Support in vSphere Using PowerCLI in 30 Seconds. :)

This applies to virtual switches that have already been created.

I was trying to do this earlier this evening and found a few articles that talked about various methods to enable jumbo frame support on a vSwitch.  After reading some of the ‘hacks’ that are being used, I decided to dig into PowerCLI.  Amazingly enough, the solution is so simple that maybe it’ll get some of the people working with vSphere to move into PowerCLI further.  Here’s the 30 second or less solution to the issue.  As I wrote above, this applies for a vSwitch that’s already been created, but you can create a vSwitch with all the specifications you need from PowerCLI as well just the New-VirtualSwitch commandlet.

> $vs = Get-VirtualSwitch –name vSwitchX
> Set-VirtualSwitch –VirtualSwitch $vs –mtu 9000

> Get-VirtualSwitch –name vSwitchX

If you’re not familiar with PowerShell, get familiar with it. 🙂 It’s an excellent product and is expandable so many IT products are moving toward a PowerShell interface for its ease of use.

vSphere PowerCLI Commandlet Poster

Pablo Roesch, VMware, has put out a poster that their marketing department did, that has a listing of the PowerCLI commandlets.  This is a very useful tool for anyone working in PowerShell using the VMware Toolkit for Windows.

It’s originally posted in this forum a VMware forum: http://bit.ly/1602Au

I’ve placed a the file in my media library and linked to it from here, just in case it disappears. 😉

Windows PowerShell sticker, and /n Software for free

So after following a link from a buddy’s blog, Bobby Shea, I started browsing around /n software’s web site. I filled out the form for a free Windows PowerShell Sticker, again – yes, they didn’t send it months ago the first time I tried, and I found something else interesting on their site.

Months ago, the first time I visited /n’s site, I downloaded a trial version of Netcmdlets.  Netcmdlets is /n’s PowerShell snap-in that extends PS into remoting, SSH, and other network protocols.  I ended up uninstalling the software after the trial was over.  Now, the software is FREE for hobbyists!  Since I’m not using PowerShell for work with clients, restricting my PS activities to my home network and ‘playing around’, I’m qualified as a hobbyist!  I’m on my way to download right now!

If you’re not familiar with NetCmdlets, you should definitely check out the site, the description, fill out the form for your sticker and keep your fingers crossed, then download the hobbyist version, unless you’re planning on using it commercially in which case, pay /n some money. 🙂

A quick list of the features, taken from the /n site are:

Device Management SNMP device monitoring and management capabilities, complete with SNMPv3 Security.
Remote Access Secure Shell enabled remote execution using Rexec, Rshell, or SSH.
Directory Administration Access Active Directory or OpenLDAP servers through LDAP Directory Access.
Email Send & Receive Send HTML Emails or Emails with file attachments. Retrieve Email through POP or IMAP Connectivity.
File Transfer File transfer capabilities through FTP, TFTP, & RCP connectivity.
Instant Messaging Jabber Instant Messaging, SMS messaging, and Alphanumeric Paging.
Network Monitoring Listen and react to SNMP Traps and Syslog event messages or access raw Ethernet Packet captures.
Access to Web Services Connect to web services through HTTP and RSS client capabilities.
DNS Configuration Monitor DNS and other network configuration changes.
Encoding / Decoding A complete array of utility encoding and decoding capabilities including MIME, UUEncoding, URL, Hex, etc.
Zip Compression File compression including password protection, AES Encryption, and 4GB+ archive support.

This is really good stuff, at a great price, free!  Check it out.  If you type instead of click, and you know who you are, you really need these tools.
