DHCP on Cisco Catalyst 2950 Switch

Hello

I need to configure my cisco catalyst 2950 series switch in order to act as DHCP server for devices connected to its ports.

Please say me, how to do that ?

Thank you

Hi Narek,

The DHCP server feature is not supported on the 2950 switches.

You would need atleast 2955 to act as a DHCP server.

check this link for more information

Thank you

Then please say me, how to do that on Cisco Catalyst 3550 series device.

Thank you

Re: DHCP on Cisco Catalyst 2950 Switch

Please find the sample DHCP configuration for one of the VLANs.

Interface Vlan1

description Cisco DHCP

ip address 10.10.2.1 255.255.255.0

ip dhcp pool cisco

network 10.10.2.0 255.255.255.0

default-router 10.10.2.1

domain-name mydomain.com

dns-server 10.10.2.10

netbios-name-server 10.10.2.15

lease 7

A 24 hour lease is the default if left out and the netbios-name-server is WINS in the Windows world.

If you want to use DHCP server for other VLANs as well create similar DHCP pools and assign the DG to the corresponding VLAN interface IP.

HTH, rate if it does

Re: DHCP on Cisco Catalyst 2950 Switch

I need to give DHCP addresses from 192.168.5.0 network , with exclusion of 5.1, 5.2 and 5.3 to FastEthernet port 0/20

Plase more detail

THANK YOU

Re: DHCP on Cisco Catalyst 2950 Switch

What do you mean by excluding the ip addresses to fa 0/20

If you want to exclude the IP addresses from the pool, it can be done.

Let me know the interface vlan ip address that will be assigned as the default gateway for the desktops

Re: DHCP on Cisco Catalyst 2950 Switch

Okay , let me formulate by another way.

I have Cisco Catalyst 3550 series switch with

IOS version : 12.1(14)EA1a

I need to connect to FastEthernet0/20 port one non-managable hub/switch so computers which will be connected to hub/switch (20-50 computers) may get IP address from ONLY that FastEthernet0/20 port DHCP service.

But for example, if I plug to FaEth0/15, I get no IP address, nothing.

And also I have 5 ports active on same switch FA0/1-0/5, and I don't want to disturb that servery anyhow.

Thank you

P.S.

I cannot put any PC for DHCP service for this solution.
