My Boss’ DHCP Experiment on a 2950
My boss recently let me know of some interesting stuff he was doing with a Cisco 2950 24 port switch. Apparently you cannot make a 2950 a DHCP server, but if you flash the 2950 to use a 2960 lanbase image, it works just fine!
Below is my boss’ text. Any questions, tweet him @RayGodwin1
My first inclination would be to say no, but I went and checked on a 2950 running
(C2960-LANBASEK9-M), Version 12.2(25)SEE2 and it appears to work! I say appears as I am remote from the switch and cannot (yet) validate operation.
Below is the sequence to configure it. As its a layer 2 switch we are restricted to servicing only request from 1 VLAN (in this case the default vlan 1) I did a show command to see what the address was on int vlan 1.
Switch2950#show run interface vlan 1
Current configuration : 78 bytes
ip address 10.3.3.57 255.255.255.0
no ip route-cache
Enter configuration commands, one per line. End with CNTL/Z.
Switch2950(config)#ip dhcp pool test
Switch2950(dhcp-config)#network 10.3.3.0 /24
Switch2950(dhcp-config)#ip dhcp excluded-address 10.3.3.1 10.3.3.49
Switch2950(config)#ip dhcp excluded-address 10.3.3.60 10.3.3.254
Switch2950#show ip dhcp server statistics
