Firstimer using Cisco Router

Bryan Librojo
Level 1
Level 1

Hi Guys,

I'm Khris, and im new in cisco routers, i never been using cisco routers before and now i have to work for it because i needed to.

i have cisco c887va-w-e-k9 router and its already reset to its default config. as in no configuration at all, im new in cisco thats why i read a couple of websites about cisco until i know some basic commands from youtube, and i dont know what is the certificate that i will see in the running config is important because it say that it was expired. what i want to be done is below

1. internet access

2. dhcp

3. wireless connection

i tried to configure the internet and dhcp, but i got a problem in dhcp, it does not release any ip on the network, to try the internet is working i put static ip address on lan and its working fine, my problem is the dhcp that is not providing any ip in the network. i reset again the router to make it clear.. is there anyone who can help me, i know my problem is not that difficult because what i really need to be done in my router is just a basic configuration. but like what i said, its my firs-time configuring a cisco router thats why im having a hard time on it...if there's anyone who have their spare time to help me is to much appreciated..sorry for my english...english is our second language. im looking forward for someone to help me with my problem..thanks cisco.

Thank you Bryan,

The interface FastEthernet 0 looks down down, is the switch or PC connected to that port?

Thank you Bryan, I see up your interface and the SVI 10 as well. It is weird, you should be obtaining an IP address. Please let verify again.

It should not be a mandatory requirement but try including: ip domain name test.com

Also the configuration on the port:

interface fastethernet0
switchport
switchport access vlan 10
switchport mode access
no shutdown

if you like sir we can connect via teamviewer for you to see in actual my running config??

Hi Bryan,

Yes it could be but before could you please provide me the output for:

show vlan 

or 

vlan database.

Thank you in advance.

Apologies, try to verify if you are getting IP address through the switch or directly connected to the router.

Hello Sir, 

I lost electrical power yesterday that's why i cant reply... about the connection it still not working...and why this command line "switchport mode access" does not appear in my show run config? is that ok???

Hi Bryan,

No worries, I will be here to assist you anytime.

It could be normal on this kind of routers, may I know the IOS you have, it could be originated by license.

could you please share:

show version 

Thank you
