Hi gurus


I'm wondering is't possible to configure multiple DHCP pools to ciscos IOS     12.2(25)SG software.

I'm having multiple VLANS and would like to give every VLAN own DHCP pool, i.e.

VLAN 10  --> 10.1.10.0   /24
VLAN 20 -->  10.1.20.0   /24

....



Thanks for any help

No, this is not my case

First of all, I'm using 4503 with SUP II (IOS :12.2(31)SGA) and the command syntax is little bit different.

How ever, everything  should be OK:


----------------------------------
show running:
ip dhcp pool VLAN40
   network 10.71.40.0 255.255.255.0
   default-router 10.71.40.1
   dns-server 196.33.222.100
   domain-name foo.com
   netbios-name-server 196.33.222.100
   netbios-node-type h-node
   lease 14


Switch_2#sh ip dhcp server statistics
Memory usage         5911
Address pools        1
Database agents      0
Automatic bindings   0
Manual bindings      0
Expired bindings     0
Malformed messages   0

Message              Received
BOOTREQUEST          0
DHCPDISCOVER         2
DHCPREQUEST          13
DHCPDECLINE          0
DHCPRELEASE          0
DHCPINFORM           30

Message              Sent
BOOTREPLY            0
DHCPOFFER            0
DHCPACK              0
DHCPNAK              11
Switch_2#


Switch_2#sh dhcp server
   DHCP server: ANY (255.255.255.255)
    Leases:   0
    Offers:   0      Requests: 0     Acks: 0     Naks: 0
    Declines: 0      Releases: 0     Bad:  0


This look for me that it doesn't get any DHCP request at all ??

Buy the way, the VLAN switch is another switch, so is that the problem, ie. I need to configure to same switch bouth, VLAN and DHCP pool ???


Thanks  for any help

Found it !! becuase the switch is different network subnet, I needed to expand DHCP to another VLAN by giving a command

conf t
 int vlan 40
  ip helper-address "SWITCHS IP ADDRESS"

thast it.

I remembered, that DHCH broadcast messages dount go thru subnets.


Thanks all
