Generally, we enter in this mode while the password recovery process or Backing up of IOS on devices like TFTP server. We can enter this mode when we interrupt the boot process of the router. Assigning an IP address to an interface, bringing up the interface are the common tasks done in this mode. In this mode, only the configuration of interfaces is done. In this mode, different configuration like making a local database on the router by providing username and password can set enable and secret password, etc.
Commands enter in these modes are called global commands and they affect the running-configuration of the router. Different commands like show running-configuration, show IP interface brief, etc can run on this mode which is used for troubleshooting purposes.Īs we type configure terminal to the user mode, we will enter into the global configuration mode. This mode is limited to some monitoring commands.Īs we type enable to user mode, we enter into Privileged mode where we can view and change the configuration of the router.
Difference between Private and Public IP addressesĪs soon as the interface up message appears and press enter, the router> prompt will pop up. Difference between Synchronous and Asynchronous Transmission. nslookup command in Linux with Examples. Implementation of Diffie-Hellman Algorithm.

I don't think they would be opposed to spending a bit of money <$100 to get a program if it isn't possible to do otherwise, but scripting is not my field and i'm not sure if there is an easy way to do this. that they can just run that will login to the router and issue the reload command? That way they can have it on the IT guy's desktop and he can run it without having to login and reload it manually every time. The question is, is there an easy way for me to setup a script/batch file/etc. Now I realize that this isn't the best solution for the problem, but they don't want to spend much time/money on the problem and the tunnel isn't heavily used, so a reboot works for them. We don't have access to the main router terminating the VPN, so usually all they do to get the connection back up is reboot the router and the tunnels come right up. The problem is that about once a week, it stops passing traffic. I have a client that has an 871 router that connects to US customs via an EZVPN tunnel that we have no control over.
