DHCP on 2960

nowal1234 · ‎08-01-2007

I have ASA5505 and Catalyst 2960.

I want make 3 vlan on switch and make 3 network. Ip must be assign by dhcp on 3 vlan range of address 192.168.10.xx ports 1-10, 192.168.20.yy ports 10-15, 192.168.30.zz ports 15-20. It's really? How can i do it? If you write examples it be good.

Hi

AFAIK its not possible to make 2960 to act as a DHCP server.

You need a L3 device which can support DHCP server feature to do the same..

Hi Prem,

2960 can be configured as DHCP server.

HI Prem, [Pls Rate if Helps]

Cisco 2960 can only act as Relay agent for DHCP Services. Which can forward the Packets between clients and Servers. Relay agent forwarding is different from normal L2 forwarding.

You need a Windows / Unix DHCP Server which advertises the below subnet ranges:

192.168.10.xx ports 1-10, 192.168.20.yy ports 10-15, 192.168.30.zz ports 15-20

Whereas you need to enable DHCP Services on the Switch using "service dhcp" command to allow the Switch act as DHCP Relay Agent. For me by default this feature is enabled.

PLS RATE if HELPS

Hi Everybody,

2960 can only be configured for dhcp snooping and not as a DHCP server.
