RouterGod Celebrity Workshop Presents
Tonya Harding Configures The Cisco 700
Welcome to another of the Celebrity Workshop Series. This week we are proud to bring to you sports legend Tonya Harding. We selected the 700 series router from Cisco because of it's hardened case, quality construction and it's reputation for being able to take abuse. We asked Tonya Harding to configure it because of her ability to dish out the abuse. Truly a larger than life character, Tonya is a hard drinking, tough talking, iron pumping, truck driving woman who always seems on the verge of physical violence. We didn't like her at first but after we got to know her we all thought she the most fun guest we've ever had. She even gave McClenny her phone number, but he's playing it cool, acting like it's no big thing. If you would like to see more lectures from Tonya, let us know. As far as "The Gang Of Nine" here at RouterGod is concerned, it's unanimous, we loved her. And now, Ladies and Gentlemen, Tonya Harding:
"Ever wonder what happened to all those old obsolete 25 Mhz 386 Intel CPU chips? Don't ask!
Tonya on Model Numbers
"If it ends with an even number it has an S/T and a U interface. If it ends with an odd number, it only has an S/T interface, and boy, that's odd!"
"If the middle number is a 6, it only has one ethernet port. If the middle number is a 7, consider yourself lucky 'cause it has a 4 port ethernet hub"
"If the last number is 1 or 2, no analog ports for you! If the last number is 5 or 6, you have 2 analog ports to fix!"
"If it has the suffix M, that means it is packing an awesome 1.5 Megabytes of RAM"
Tonya Stepping Out.
"I was doing just great until my boyfriend and his dopey friends ruined everything. But it's not too late for you. Get your CCNP the honest way, through study and hard work. There's no need for violence, unless it's absolutely necessary"
Hey you guys! What's cooking? First I'd like to say thank you to RouterGod Online Magazine for inviting me here and thanks to all you for showing up! Alright, let's get down to business with this little puppy.
This little guy is the smallest router Cisco sells, it don't even run IOS. It is aimed at the telecommuter market. Cisco says this guy can be set up in 30 minutes by a non technical person, so here I go! It's an ISDN box that runs IP and IPX. At first I found it difficult to figure out but once I got used to it I kinda liked the little bugger. I'll bet Cisco sells a million of these puppies!
I was playing with the 772, it's got a 4 port Ethernet hub built in. Pretty Cool, you could have a remote site with 3 workstations and a JetDirect printer and you would only need cable. Also, their shape is perfect for wedging under wobbly tables and stuff.
Even though this little squirt is aimed at the Home Office, Small Office crowd, it does some pretty amazing tricks. Like PAT translation. It will track up to 400 PAT entries on your inside network using a single IP address. Imagine 400 users downloading MP3s and Warez across your BRI connection. Sounds like bottleneck city if ya ask me, and most folks do. Also the way it's setup, it's impossible to ping an inside address from the outside, even an inside global.
The 700 supports CHAP and PAP authentication and it can be a DHCP server or it can relay DHCP requests and stuff. It can do access lists and will run RIP and RIP2 or what I call "Son Of RIP". Oh Yikes! It also does Snapshot routing, that's pretty trick, ya gotta admit.
Yesterday I got it all configured and without thinking I shut it off, Oh No! I thought, there goes my configuration! But I'm not the sort of girl to lay there and whine "why me? why me?"...no way Jose, so I turned it back on and what do ya know! My config was saved in NVRAM, just like a switch! I was a happy camper.
Ok guys, here's whatcha gotta know, the 700 configuration is stored in what Cisco calls a profile. These profiles are kinda like sub directories in DOS. Each profile contains configuration parameters for a given connection. You can have a maximum of 16 "user profiles". The user profiles are can come and go, you can add and delete them all day long. There are 3 permanent profiles called Lan, Standard and Internal. There is one last profile called the System profile. So that makes 16 user profiles, 3 permanent profiles and the System profile for a total of 20 profiles. You can configure this router in 2 modes, System mode and Profile Mode. The System Mode (or System Profile) is for global configuration stuff like ISDN switch type and assigning a system name.
The LAN Profile is for configuring the Ethernet port and routing, since it's not IOS based the command syntax is kinda funny. Here is where you put in the IP address, Subnet mask and routing configuration.
The User Profile is to predetermine the characteristics of the interface when a connection is made to a specific site. As I said you can have up to 16 user profiles. One can be called "Downtown" when you want to connect to the downtown office or you can have another called "Warehouse" that contains the configuration setting necessary for dialing up the warehouse.
The Standard Profile is there to handle unknown, incoming ISDN calls.
The Internal Profile is used to configure how data is handled as it is passed between the Ethernet interface and the ISDN interface. You will probably never have to screw with this.
OK, let's configure this puppy! After you jam a cable into the DB-9F console port all you get is a prompt that looks like this: > Pretty dull. So lets give it a name:
> set system tonya_harding (enter)
Not too shabby! Lets create a user profile:
tonya_harding> set user downtown (enter)
When you create a new user profile like we just did, the context of your prompt changes and you are now in that specific user profile. Any thing you do will be done in the context of the "downtown" user profile. By default, your new user profile "downtown" is inactive. Let's activate it:
tonya_harding> set active (enter)
If it were an existing user profile, we could de activate it by using the "set inactive" command. You can create up to 16 user profiles and by default the router will only dial the one that is "active". If you wanted to, you could enable the router to dial multiple destinations by using the command "set multidestination on". To see which one that is, enter "show users".
To move your context from one user profile to another you use the "cd" command just like in DOS. Say you are in the profile named "downtown" and you want to configure the "warehouse" profile, you do this:
tonya_harding> cd warehouse (enter)
Sometimes you need to reboot this puppy, guess what the command is? Way to go boyfriend! The command is "reboot". If you want to restore to factory defaults the command is set default. Let's set some ISDN parameters while I'm on a roll.
tonya_harding> set switch 5ess
If ya need to configure SPIDs the commands are:
tonya_harding>set 1 spid
This little puppy can be set to autodetect the SPIDs:
tonya_harding>set autodetection on
In fact, I would try to let it autoconfigure first, then pound it in manually. Don't forget that you gotta configure ISDN at the user profile. And get this, boys, you gotta configure routing at the user profile too. Say you have 3 user profiles and you want to enable routing for each one, you guest'er Chester, ya gotta do it 3 times. Not only that, but you have to enable it for the active user profile AND the LAN profile too. Did you think you were gonna get away with just enabling it at the LAN profile? No way Dude! And wait to you see this crazy syntax:
tonya_harding>set ip routing
You can also enable bridging, but ya can't bridge and route the same protocol. Why would you want to? Here's how to configure IP on an interface:
tonya_harding>set ip address
Check your work:
tonya_harding>show ip config
To let the 700 forward BOOTP packets so it can talk to the DHCP server in the main office enter:
tonya_harding>set dhcp relay
You can also set it up to act as a DHCP server and it will give out the extra goodies like DNS server, WINS Server and you can configure the lease time and stuff. I'd recommend this book to get the skinny on this DHCP stuff as well has get up to speed for the BCRAN test:
Tonya Answers Questions
Doug If I use my 700 Series router for voice calls do I need to buy a special ISDN telephone?
Tonya Not even! It's got 2 RJ-11 jacks in the back, but make sure your ISDN line is provisioned for voice.
Irfan My remote PCs are configured with a WINS server, how can I keep them from bringing up the line every time they boot up?
Tonya Use NetBios Name spoofing to intercept those requests.
