How do find the IP address assigned by a DHCP in my cisco catalyst 6513?

Hi

I am having trouble finding what DHCP is assigning the IP address to our new phones, I have a DHCP that i have access to that assigns IP address to all other devices, however the IP range of the phones is not listed and that might be because i have a second DHCP  most likely configured in one of my core switches. I am not sure where i can confirm this and i am needing to configure our phone system with a system set for multicast so we can send out alert notifications on all phones and intercom system in case of an emergency. please help !

I guess the question is does the ALGO get its IP via DHCP or is it statically defined, meaning you configure the IP on the ALGO?

Don't know how the ALGO works, but if it uses DHCP, just change the port its in to the voice VLAN and either bounce the port or reset the ALGO and it should then an IP in the voice VLAN. To get the IP of the ALGO then, do "sh mac address-table int X#/#", where X#/# is the ALGO port on the switch, then do "sh ip arp xxxx.xxxx.xxxx" where the x's are the mac address from the previous command.

If the ALGO IP is statically defined, give it an IP (again, outside the DHCP scope) and change its port to the voice VLAN.

If you need further help, just specify.

Thanks

Thank you, the algo is getting its IP from DHCP so i would need to move it to the voice VLAN.
