i have some questions:
1. How can i configure the router ip address (not interface ip address), so i can telnet into the router acn connect the router using Internet Explorer. I know the command ip address subnetmask,but from which prompt can i use this command.
2. I like to use the Internet Explorer to connect to the router, which software i need to add to the router so that it can be connected using IE?
3.which bit in the configuration register that made the router loading IOS in flash memory?
best regards and thanks
#1 Not sure what you mean by a router IP address that's not an interface IP address. Closest thing to a router IP address that come to my mind is using a loopback address but that's also an interface address.
To be able to telnet into the router, you'll need at least one interface address (that's reachable to/from the device you're going to telnet from - usually on the same subnet as the physical port's IP works), VTYs defined (usually 5 by default), VTY's that don't block or limit telnet access with an ACL (usually don't by default), VTYs must allow telnet transport (usually do by default), VTYs need password (usually NOT by default).
The ip address command would be used similar to this:
interface fastethernet 0/1
ip address x.x.x.x x.x.x.x
If you can not telnet to the router, you connect via the console port unless security settings block/restrict console access, if they do, you'll need to follow the console password recovery procedure (and also hope it's not a very recent IOS with security configured to defeat normal password recovery).
#2 As Narayan notes, SDM can be installed on many routers to provide an advanced web interface, however, I recall most offer a limited command line web interface without need for software installation.
In addition to needing IP addresses and insuring ACL don't block access to HTTP, you'll also need to insure that the web server (ip http server) is active (default, whether active or not, I believe varies per IOS) and what port it's using (usually port 80). Depending on IOS feature set, HTTPS can also be provided. (Don't recall the default authentication requirements for HTTP access. Might be able to use telnet prompts, might require at least a local user account on the router.)
#3 Bits 0..3, see http://www.cisco.com/en/US/products/hw/routers/ps133/products_tech_note09186a008022493f.shtml for more information on the configuration register.
1. The router needs an ip address on any one of its interfaces to telnet or http into it (your machine should be a part of the same subnet)
2. You need SDM on the router to connect to the router via HTTP
3. if you meant the configuration that should be loaded, it is 0x2102
Have a look here for the boot sequence
