What is the minimum configuration necessary to use...CCP?

[Chris Simon]

Now that I'm using CCP instead of SDM[1], there are a few details of the CCP Configuration Guide[2] that don't work on the 871w. The CCP Guide says there needs to be some minimum configuration in order to use CCP including the commands[3]:

Router(config)# int FastEthernet0
Router(config-if)# ip address 10.10.10.1 255.255.255.248
...
Router(config)# line vty 5 15

"% IP addresses may not be configured on L2 links." will come up if you are trying to assign an IP address on a layer 2 interface or "switchport".

I followed the instruction in this link[5] which explains once the vlan is configured it becomes the default for fe0-fe3,

Notice that we configured IP addresses only to fast Ethernet 4 and vlan1. By default, interfaces fast Ethernet 0 to 3 are assigned to VLAN1 so anything you connect to those interfaces (internal LAN hosts) will belong to vlan1 network range 192.168.10.0/24 and they must have as default gateway the address 192.168.10.1.

The router is connected by the console port to 9pin on my CentOS server using minicom and with straight-through ethernet between Windows Vista, Business Ed. running CCP 2.7 and FE0 (while I'm using WiFi to write this). Here is my IOS config[6].

So far discovery has failed in CCP. What am I missing?

UPDATE 08-18-2014:

After having created a successful install, and now needing to restore the 871 a second time, I now know what I didn't know before. The 871 is configured as a switch and not as a router despite the 871w being referred to as a router. The instructions for minimal install for a switch (with ip on vlan interface) described here Cisco Configuration Professional Quick Start Guide is successful. I can't be sure why it didn't work the first time, but I've since learned the minimum install for CCP is also the same for TFTP. Since tftp is simpler to verify using ping and tftp server app instead of CCP with Java, I would recommend using the CCP Quickstart steps for setup and TFTP for testing the connection.

Here's something I find weird. The newest version of the CCP End-User Guide for version < 2.8 seems to be 2.5[7]. While the "Cisco Configuration Professional Quick Start Guide" (link 2 above) has the section, "Configure the Router for Cisco CP", the End User Guide doesn't have this section despite its 1976 pages.

That would have been a good place to cover special case. I've spent the whole day trying to get the router configured for CCP to start configuring...go figure!

hi chris,

is this your 871w router? do take note FE0-3 ports are layer 2 capable ONLY.

you'll need to create a layer 3/SVI interface for routing.

int vlan x

ip add

int fx

switchport mode access

switchport access vlan x

[Chris Simon]

I didn't understand what fx meant (now I understand its one of the shortcut commands). A search for 871 vlan setup lead me to the most comprehensive config page I've found yet CISCO 871W configuration for small offices.

While I don't want the configuration this blog creates, the instructions were sufficient to enable CCP 2.5 to connect.

I also discovered there is some other problem where this configuration won't work. While applying only one of the vlans to the interface, I got an error "vlan cannot be added, maximum number of 2 vlans in the database".

hi chris,

the 'x' means any number, i.e. int f3.

i suspect your current IOS has a VLAN limitation. kindly post show version.

you'll need to run an avanced ip services image.

[Chris Simon]

"you'll need to run an avanced ip services image."

Isn't this behind a pay wall? This, er...7+ yro, router I got off ebay. i don't have a contract.

Some specifics of my router include,

IOS 12.4(15)T6

System file image: flash:c870-advsecurityk9-mz.124-15.T6.bin

871W processor with 116mb/12mb ?

128K of configuration memory

24mb system flash

[johnlloyd_13]

hi chris,

your current IOS is restricted to 2 VLANs only.

you'll get 10 VLANs if you downgrade to 12.3.

you can "google" to obtain the right IOS.

[Chris Simon]

The above settings were sufficient for device discovery, but also added other difficulties--failing other configuration within CCP.

I've revisited all the sites I've read and written the steps in long form CLI commands step by step.

I'm sure mine isn't a minimum configuration, but it appears sufficient to use CCP--so far.
