DEPLOYMENT OF CISCO ISR 900 ROUTER, C921- 4PLTEGB MODEL

[BenedictOwusu72748]

Please my name is Benedict, i have procured a Cisco router ISR 900 series C921-4PLTEGB for failover solution and i want assistance on how to set it up through HTTP management. I am yet to order for an RJ45 to USB CONSOLE cable. I will really appreciate a kind gesture of opinions about implementing this device most especially if i can also be provided with the IP address of this device to be reached through http.

FAQ: What web-based or GUI tool is available for the 900 Series ISRs?
You can configure and manage the 900 Series ISRs with Cisco Configuration Professional.

The default configuration file assigns an IP address to a LAN interface on the router, and you must configure the PC to be on the same subnet as the router LAN interface. If the router is a fixed-interface model, it is configured as a DHCP server, and the PC must be configured to accept an IP address automatically. If the router can accept modular interfaces, it is not configured as a DHCP server, and you must configure the PC with a static IP address on the same subnet as the router.

If you are lucky you do not need to configure the ip-address

connect your PC to the router only and no other network !!! and check if you received an ip-address for the router (windows-> ipconfig /all, linux ifconfig -a)

in the dhcp information you will find the routers ip address in two fields as dhcp server and as default gateway

Thanks for your response and the heads up.
Will try it and give a feedback when I resume work at my office as I'm currently working from home.

Hi Pieterh and Ben, I bought the c921-4P, however I have difficulties setting up thru CLI. I have not much experience in Cisco CLI.

The link Pieterh provide, I cant seem to find the software download in Cisco https://software.cisco.com/download/home

I tried plug directly from my PC to the Router switchport or the WAN, i cant get any DHCP ip unless i set it static.

These are my configuration, hope to get reply from you. Thank you! =D

Hello,

what does your topology look like ? Is this router directly connected to the Internet, or is there an ISP (modem) on front of your 921 ?

What are your internal networks ?

Hi Georg,

Thanks for getting back! 

I manage to sort out thanks to Pieterh, what im missing is VLAN interface

int vlan 10

ip address 192.168.2.1 255.255.255.0

no shutdown

after setting above, my PC could get IP

hope can help someone in the future!

Hi James it would have been better to start a new thread, instead of replying your question to an existing thread

but that sayd....

1) the software can be found using

• Downloads Home
• Cloud and Systems Management
• Routing and Switching Management
• Configuration Professional
• <version>  e.g. Configuration Professional Software- 3.5.

2) are your DHCP clients connected to vlan10 ports?

- you have a pool ip dhcp pool vlan 10 and a pool dpool1

- you have a client port in vlan 10 like 
     interface GigabitEthernet3
     switchport access vlan 10

- but you have no interface vlan10 !  only interface Vlan1

  -> add an interface vlan 10 with ip-address from  192.168.2.1 (the default-router configured in this dhcp options)
      or an interface vlan 10 with ip-address 10.10.10.10  (the default-router configured in that dhcp options)

Hi Pieterh,

Apologize for not creating a new thread, i am so new to this =D

Much appreciate for your reply!

should I create a new thread and redirect it?

1) I tried the link you recommend, i only find 3.5 express, can it work? see attached

2) thanks Pieterh! it worked!

int vlan 10

ip address 192.168.2.1 255.255.255.0

no shutdown

1) looks like Cisco CP stopped at version 2.8, new versions are only Cisco CP-Express

there is a dependency with the device-model and IOS version on the device

version 2.8 does NOT list the 900-series , 3.5.3 list your model C921-4PLTEGB  

-> yes you can use this version,
