Connecting to and Configuring Cisco Routers with ‘Cisco Configuration Professional’
KB ID 0000512
It’s not often I work on Cisco routers, but as I tend to do most of the Cisco ASA Firewalls, I’m the unofficial “Cisco Guy”. Which is fine until someone wants a router or some complex switching, then I need to do some heavy duty frowning.
Last time I put in a Cisco router it was a baby Cisco 800 series (an 877W) so I assumed the 1921 ISR router I had to put in would be the same. Before I used the Cisco SDM console that’s now either depreciated or not used, and a quick look in the flash memory of the router told me there was nothing in there apart from the IOS.
Now for all your web based router needs, you use the “Cisco Configuration Professional” software, it comes in two flavours:
1. Express – this installs on the router itself and is a cut down version.
2. PC Version – the full suite of tools installs on a Windows PC (that has Java installed) Note: is does NOT need anything else installing on the router.
Note: If you get an error message like “IP address may not be configured on L2 Links” then assign the IP address to the VLAN (usually, but not always VLAN 1).This is seen on smaller 800 series routers, to resolve also make sure the Ethernet port is NOT shutdown like this;
interface FastEthernet0 ! <<<<<<<Note: Make sure the Ethernet ports you will use are NOT in a shutdown state! interface FastEthernet1 shutdown ! interface FastEthernet2 shutdown ! interface FastEthernet3 shutdown ! interface Vlan1 ip address 192168.1..1 255.255.255.0 <<<Or use DHCP as appropriate
4. So all being well, this is what you should see if you issue a “show run” command.
5. Lets make sure it got an IP address with “show ip interface”.
7. If discovery fails make sure you’re cabled correctly and select “Discover”.
8. It connects over https so it’s normal to see this, just click yes.
9. You can now configure the router as required.
10. If you have the Security/Firewall IOS you can also manage that from here.
