More subnet in DHCP Server

[wasiimcisco]

I have 3750 switch with Version 12.2(25)SEE3. I am running DHCP server on it for data/voice

I am running 172.28.92.0/24 for data and 172.28.93.0/24 for voice.

Ports are configured both for data/voice.

Now i want to add another subnet because users are getting IP address outage.

Please let me know how to add another subnet for voice and data and how to confiugre this subnet for DHCP server. How to configure the VLAN for this.

I will be very greatful to you.

Hi

U need to configure another dhcp pool along with the excluded address same as it is done for the earlier dhcp pool.for eg:

ip dhcp excluded-address 10.30.28.1 10.30.28.50

ip dhcp excluded-address 10.30.28.201 10.30.28.254

ip dhcp pool users-bldg10

network 10.30.28.0 255.255.255.0

default-router 10.30.28.250

dns-server 10.30.28.10 10.1.6.6

netbios-name-server 10.30.12.10 10.1.6.6

Thanks

Thanks for the reply,

but right now i have two vlan one for voice and one for data.

If i will include this pool in DHCP configuration. How to deal with Port configuration for vlan.

All ports are member of VLAN 100 and VLAN 110.

Will there need to add new vlan and assign the port to that vlan also.
