Well I got a S/H Cisco 857 but cannot configure the thing, as the Cisco software cannot find the router :(

Does anyone have an idiot's guide to getting this thing up and running? as the docs I have looked at (including Cisco's own) haven't helped much so far

Thanks
 
If you are not 100% on the IP address it's time to crack out the console cable.

Setup a terminal session on COMx (whatever you serial port is) and set it up as 9600,n,1,n and you should get into the router.

You might need to login at this point, you might not. If it prompts you to login, then enter the username and password.

You then need to go into enable mode - type EN and hit return, then it'll ask for the enable password. Enter this and then the prompt should change to a #.

Type "sh run" and it'll start outputting the running config. Scroll through until you see a reference to the ethernet interface (probably Ethernet0 or FastEthernet0 or FE0....something like that) and check the IP address. Also check that it's enabled (NO SHUTDOWN). If it's not the same as you expected then you can either setup your PC to match the routers subnet and SDM in and set it up that way, or change the interface address.

Sorry if there is an easier way - I'm no Cisco expert (I've had a 837, 1721 and 1841 in the past) - but I didn't really have to do much on them.
 
Console is the only true way.

Pretty much all Ciscos have one and it's much easier than trying to connect via network stuff, plus saves frustration when you change something that causes the connection to drop.

Usually they ship with a "light blue cable of win" in the box. Though i couldn't say for sure as I only really deal with enterprise stuff; 1800/ 2650 /2800 and so on, but it's unlike cisco to break the habit of a lifetime.

If you're unsure on serial settings, putty.exe works on it's default settings.
 
Yeah I have had a play with the console before, but to be honest, I don't really know Cisco gear... ANyway, no IP assigned:

interface FastEthernet0
!
 
If you need help there's plenty on here who can. Just let us know what you want to do and we can tell you how.
first steps would be adding an enable password, ip address and telnet password via
enable
conf t
enable secret <your-chosen-password>
int Fa0
Ip address <desired ip> <subnet mask>
no shutdown
line vty 0
password <desired password>
login
end
service password-encryption
copy run start


Quickest way is to copy that into notepad, replace the values with the ones you want, copy it then do a "paste to host" in hyperterminal.
Then you can connect to it via telnet on it's ethernet interface and possibly with the software.
 
You don't configure the VLANs on the router itself, only the trunking which is done with sub-interfaces I believe.

The actual VLAN setup is done on the switch.
 
Ok I tried following your commands, but I get:

Router(config-if)#ip address 10.10.0.1 255.255.255.0

% IP addresses may not be configured on L2 links.

This is my config:

ahh right, this router has an integrated managed swtich. You will need to apply the IP address to VLAN1

config t
int VLAN1
ip address 10.10.10.1 255.255.255.0
 
Hi,

Thread resurrection, but I am unable to get my ADSL working. It just cannot connect to anything (i,e, the DNS server, all connection tests fail when pinging, etc)

I am on O2 and using a fixed IP- any ideas?

Hey got it now, never mind :D

I will post my config up in a bit in case others need help with this in the future

Actually, ironically, the enterprise stuff seems often to ship without console cables. I've had quite a few 6500s and 7300s which have shipped without a console cable seemingly. All the low end stuff always has it though...
 
My working config is here... This is for O2 Broadband with a fixed IP on a Cisco 857 if it is any use to anyone in the future.

Thanks for the help all- Only took nearly 10 months, two broken O2 modems, and lots of irate phone calls to said ISP for me to pull my finger out and get this working! :D

All the stuff I've gotten recently had a naff quality RJ45-RJ45 cable and a RJ45-DB9 adaptor - Not seen a blue cable since I bought my 1841 about 3 years ago

I didnt think the 857 supported ADSL2? Or are you only on the access package?
Click to expand...

Yeah I can't get anything better on this line :(

But the router is a great bit of kit- and I actually thought ADSL 2 was supported :confused:
 
I think ADSL2+ support came with the 877, hence why i got one :)

*EDIT* It seems it does, if you have the correct firmware! Learn something new everyday!
