In the configuration mode on the router or MSFC, issue the following to start NetFlow Export. First enable Cisco Express Forwarding: router(config)# ip cef router(config)# ip cef distributed And turn on flow accounting for each input interface with the interface command: interface ip flow ingress or use old (depricated) command: interface ip route-cache flow For example: interface FastEthernet0 ip flow ingress interface Serial2/1 ip flow ingress It is necessary to enable NetFlow on all interfaces through which traffic (you are interested in) will flow. Now, verify that the router (or switch) is generating flow stats - try command 'show ip cache flow'. Note that for routers with distributed switching (GSR's, 75XX's) the RP cli will only show flows that made it up to the RP. To see flows on the individual linecards use the 'attach' or 'if-con' command and issue the 'sh ip ca fl' on each LC. Enable the exports of...

Missing in Windows 8 is the ability to view and delete all wireless profiles from your PC.  For some unknown reason Microsoft removed that feature which is very problematic if you ever need to edit a saved profile or delete one. I recently had an issue with a wireless access point that had a hidden SSID.  I had to manually setup the connection but I forgot to check the box to connect even if the network is not broadcasting. So I was able to connect the first time but all other attempts failed because the network would not show up on the new wireless charm list. When I would try to re-add the profile again using the manually create wireless screen it would fail because there was another wireless profile with the exact same name.  Since Microsoft tore out the GUI t delete and edit profiles, I was stuck. After some research I found that there is a command line utility that will let you delete profiles.  To use that follow these steps: Open up an admini...

Fix Connectivity Issues It sounds crazy, but 95 percent of all Internet connectivity problems can be solved by power-cycling both the router and the modem. Turn them both off, and then turn the modem back on first. Once its "sync" or signal light comes on, turn on your router. Use Encryption You've probably heard this before, but it bears repeating: Always enable your router's wireless security! Wired Equivalent Privacy (WEP) encryption is the oldest (and weakest) form of security; the newer (and stronger) Wi-Fi Protected Access (WPA) and WPA-2 are the best protection available today for home users. Update Your Router's Firmware All routers include internal read-only chips with embedded instructions that can be updated by the manufacturer. Router manufacturers generally update a product's firmware to increase performance as well as to resolve bugs and security issues, so it's wise to keep your router's firmware up-to-date. C...

Note : In some cases a defective keyboard can cause problems logging into an ESX host. You might want to test with a different physical keyboard if you are having difficulties with known login credentials.   If you have forgotten or do not know the password for the root user on an ESX host, you may be able to change it without reinstalling.    Warning : This can be used maliciously and should be safeguarded against through proper physical access to the host, authenticated remote console access, monitoring and protection against reboot procedures (e.g. grub password) and limited access to the management network.   For more information on security best practices, see http://www.vmware.com/resources/techresources/726 .   Note : The procedure(s) below perform a password reset. This "blindly" replaces the existing root password with a new one. This is not a password recovery mechanism.

Network Basics: Ethernet Configurations Ethernet has a variety of possible configurations, standard, fast and gigabit. Each version operates at different speeds and use different types of media. All the versions of Ethernet are compatible with each other, so you can mix and match them on the same network by using devices such as bridges, hubs, and switches to link network segments that use different types of media. Standard Ethernet Standard Ethernet is the original Ethernet and the slowest. It runs at 10 Mbps, which was considered fast in the 1970s but is now considered slow and obsolete. Standard Ethernet comes in four incarnations, depending on the type of cable used to string the network together: 10Base5: The original Ethernet cable was thick (about as thick as your thumb), heavy, and difficult to work with. It's seen today only in museums. 10Base2: This thinner type of coaxial cable (it resembles television cable) became popular in the 1980s and l...
