vMotion Interface Is Not Configured On Source And/Or Destination Error on Nexus 1000

Nexus Leave a comment

When you received the following error: The vMotion interface is not configured (or is misconfigured) on the Source and/or Destination host, you need to enable vMotion interface.

Click on your host -> Configuration -> Hardware -> Networking ->Virtual Switch

Select the vSwitch for your Management traffic (in this case is vSwtich0) -> click on Properties

View all Port properties and find the one who has vMotion and check the status.

If vMotion is set to disabled, click on Edit

Select the check box to enable vMotion

Move the desired VM to different hypervisor.

Enable Radius Authentication and Accounting for Cisco Router

Must enable Radius on your server and get the key and port number (in this case is 1812 and 1813, and key is iwanradiuskey)

Router Config:

———————————————————————————————————————————————————

hostname iwan-router

aaa new-model

// My Radius server IP address is 172.16.1.1 (which I will group it on my Cisco router as iwan-radius-server)

aaa group server radius iwan-radius-server

server 172.16.1.1 auth-port 1812 acct-port 1813

// I’ll use my Radius server for my authentication and accounting methods (I’ll called it iwan-radius-method) and use local mode for my authorization

aaa authentication login iwan-radius-method group iwan-radius-server

aaa authorization exec default local

aaa accounting network iwan-radius-method start-stop group iwan-radius-server

// I’ll instruct it to not bother of trying to resolve name into IP address and my domain name is iwan.com

no ip domain lookup

ip domain name iwan.com

// I specify which interface (in this case is my wireless interface – BVI1) to use Radius, and I’ll also use NAS-Identifier on Radius

ip radius source-interface BVI1

Allowing Incoming Connection TCP Port 29146 On Public IP Address on Cisco router

Routers & Switches Leave a comment

This list is to allow incoming connection from outside/public to connect to the public-facing IP address (Ex: 1.1.1.1 on Fa0 interface) on Cisco router for specific TCP port: 29146 that will be translated to inside IP address (one public-facing server that has internal IP address of: 192.168.1.1 with the same port of 29146 that connect to the same Cisco router of Fa1 interface):

1. Create ACL (let’s called it ALLOWCONNECTION):

access-list ALLOWCONNECTION permit ip host 192.168.1.1 any

2. Create a route-map (let’s call it MAP):

route-map MAP permit 10

match ip address ALLOWCONNECTION

3. Create IP Nat:

ip nat inside source static tcp 192.168.1.1 29146 1.1.1.1 29146 route-map MAP

4. Specify NAT direction (incoming on Fa1 and outgoing on Fa0):

interface Fa0

ip nat outside

interface Fa1

ip nat inside
