View Current IP's address in Use?

[youngoz2002]

hey Guys

What commmand would I use to view the current IP addresses being use. I'm having a problem with IP address conflicting.Please note this is the fist time I'm working with a Cisco router. I have the proper access to get to the router. Thank You in Advnace

Hi,

You can check the localy configured IP addresses in several ways:

show interface brief

show running-configuration

But these commands just check the local router, on the other router there can be the same IP set, so you need do this checking on your all manageable devices.

Please rate me if I helped.

there are a few ways to see what IP addresses a cisco router is aware of:

1) do a 'show arp' at the router prompt. (to view all arp entries the router has)

2) check the DHCP server if the router is running one with 'show dhcp server | lease | pool (to view any DHCP pools/leases the router is handling)

3) do a 'show ip interface' to get a list of interfaces running IP. (to view all interfaces, and their addresses, configured for IP)
