SCVMM 2008 R2 Operations Timeout

Sometimes, using SCVMM on a new Hyper-V cluster to deploy a new VM may result in an operational timeout. This is an example:

Although the error message did not state "timeout" directly, you would see the following exact error when you execute "winrm helpmsg" on the error code given (in this example 0x80338029):

C:\> winrm helpmsg 0x80338029

The WS-Management service cannot complete the operation within the time specified in OperationTimeout.
The Hyper-V hosts may need longer time to respond to the VMM server using Windows Remote-Management (winrm). To increase the time-out period and to increase more concurrent operations that can be performed by the VMM server, execute the following commands on the affected Hyper-V hosts:
winrm set winrm/config @{MaxTimeoutms = "1800000"}
winrm set winrm/config/Service @{MaxConcurrentOperationsPerUser="400"}
net stop winrm

net start winrm
net start vmmagent
For other "Not Responding" host status issues on SCVMM 2008 R2, refer to this useful guide on Microsoft official site.

New Cisco L2 Catalyst 2960S supports static routes

It's long overdue! Finally, we can now configure static route on our newly shipped Cisco Catalyst 2960S L2 stackable switches. By default, you can't configure any routes on it besides the "ip default-gateway". Hence, you have to switch the sdm template from the default desktop to lanbase-routing as follows:

Switch# config t
Switch(config)# sdm prefer lanbase-routing
Switch(config)# reload

Do note that the lanbase-routing template is only supported on C2960S LAN-based image and not on LAN-lite image. For more information, refer to this Cisco documentation.
