Select Vendor Specific on the left then click Add.Select and remove the Framed-Protocol and Service-Type attributes.Click Next then click No in the popup for viewing the help topic.Uncheck everything then select Unencrypted authentication (PAP, SPAP).Click Next and make sure Access Granted is selected.Click Add scroll all the way down and select NAS Port Type.For example if you specify a friendly name of switchx, cisco devices with hostnames of switch1, switch2, etc… will have this policy applied. Enter a client friendly name (This is the hostname of the cisco device) You can use pattern matching to reduce the number of policies.Click Add scroll down and select Client Friendly Name.Enter or select the AD group you want to allow access.Click Add select User Groups click Add again click Add groups.On the Specify Conditions page we are going to add three things Right click Network Policies and select New.Now that we’ve created a client it’s time to create the network policy that applies to that client. Copy the Shared secret over to notepad or somewhere else because you’ll need this when you configure the Cisco device.Select the Generate radio button then click the Generate button.Enter a friendly name and IP address of the device.Right click RADIUS Clients, then click New.Next we need to create records for the RADIUS clients Right click the NPS (Local) node on the left, then click Register in Active Directory.When it’s done open the Network Policy Server console from Administrative Tools.Select Network Policy and Access Services.Click Add Roles on the right – the add roles wizard starts.Now let’s start with the server configuration. Why Datacenter? Because Datacenter allows an unlimited number of RADIUS clients, which will be important when we get around to using 802.1x authentication. Since we don’t like multi-purpose servers we simply created a new VM using 2008R2 Datacenter for the OS. We have a cluster of 2008 R2 Datacenter servers running the Hyper-V role which allows an unlimited number of VMs. Later I’ll be trying to get 802.1x wired authentication going but this is a start.
#BYPASS PASSWORD CISCO 2950 SWITCH HOW TO#
I couldn’t find very many resources out there for how to set things up so after much trial and error I finally have it working so I’m posting it here in hopes it will help someone else. Amazingly it seems most passwords are either cisco or cisco123. From what I’ve seen, most network admins simply have passwords set on the vty lines and an enable password set. Configuring Cisco devices to authenticate via Active Directory isn’t a common practice.
