XSM7224S Issue range of IPs to certain ports

I think you should rework your whole plan but if you must then here is one way you can accomplish close to what you are trying to do.

If you have pool range between 0.10.10.1 to 10.10.10.196 and 10.10.10.197 to 10.10.10.244

First figure out if we can even do a network for each one since the DHCP will be broadcast packet to the network and since you are addressing the ports into separate vlans we need to make sure we can get DHCP server in each network.

First let figure out the network. Since I can't do 1-196 via subnet-ting into 1 network, I will need to create pools to hande out address in 3 ranges.

10.10.10.0 /25 will get you address range of 10.10.10.0 - 10.10.10.127
10.10.10.128 /26 will get you address range of 10.10.10.128 - 10.10.10.191
10.10.10.192 /26 will get you address range of 10.10. 10.10.10.192 - 10.10.10.255

So you could split your port into 3 separate vlan and assign out address from the above ranges.

#Let make 3 vlans and assign routing interface to each to hand them DHCP address
#
vlan database
vlan 10
vlan 20
vlan 30
vlan routing 10
vlan routing 20
vlan routing 30
exit
config
#
#Let enable routing and make some routing interfaces for each vlan
ip routing
interface vlan 10
ip address 10.10.10.1 255.255.255.128
routing
exit
interface vlan 20
ip address 10.10.10.129 255.255.255.192
routing
exit
interface vlan 30
ip address 10.10.10.193 255.255.255.192
routing
exit
#
# Let enable DHCP and create the DHCP pools
#
service dhcp
ip dhcp pool vlan10
dns-server 8.8.8.8 4.2.2.2
default-router 10.10.10.1
network 10.10.10.0 255.255.255.128
exit
ip dhcp pool vlan20
dns-server 8.8.8.8 4.2.2.2
default-router 10.10.10.129
network 10.10.10.128 255.255.255.192
exit
ip dhcp pool vlan30
dns-server 8.8.8.8 4.2.2.2
default-router 10.10.10.193
network 10.10.10.192 255.255.255.192
exit
#
#Let exclude the address you don't want to give out from the pool.  The gateway address is auto excluded.
ip dhcp excluded-address 10.10.10.245 10.10.10.254
#

Thing I did not address in the above, I did not configure a default route or configure the ports. How you configure the port is up to you since I assume you plan to connect switches to XSM switch.



Now the real answer. If you read this much then I suggest you review your plan first since there are things you are not thinking about here.

Few things to keep mind.
1. Do not use Switch as DHCP server. Better to use a full DHCP server and use the switch to relay from each vlan to the DHCP server. If XSM is your core switch then you can do all your vlan routing on it as well.

2. DHCP is broadcast method so we need the DHCP to be able to respond to broadcast from different vlan, this is either done via relay or by having DHCP or switch interface on each vlan.

Example if I make a DHCP pool below on a switch which hands out address from 10.10.10.2 - 10.10.10.254 range

ip dhcp pool test
dns-server 8.8.8.8 4.2.2.2
default-router 10.10.10.1
network 10.10.10.0 255.255.255.0

exit

making the pool won't do anything since there is no way for the switch to talk to the network 10.10.10.x

Until we make a interface on the switch that can take an IP that belong to that network.

So i could make interface like this below

interface 1/0/1
ip address 10.10.10.230 255.255.255.0
routing
exit

OR we can do vlan 1 instead

vlan database
vlan routing 1
exit
config
interface vlan 1
ip address 10.10.10.230 255.255.255.0
routing
exit

Now if I connect something like a switch or PC to port 1 which is by default untagged vlan 1 then that computer or devices on that switch will get address from the dhcp pool.
OR if I connect a PC or switch to port that is tagged or untagged member or vlan 1. same applies.

Work out how many vlan you need since creating vlan means your separating broadcast (DHCP is broadcast by design) so you need to relay different vlan DHCP request to DHCP server or you need to have DHCP server sitting in each vlan either via physical connection or virtual interface as i did in first example.

Then figure out what network each vlan needs to be. Subnet the network as needed and the setup routing if needed to allow intervlan routing and setup dhcp pool for each network as needed.

If you are connecting switches to the XSM then dont' worry about ports since most port are uplinks to other switch that can hopefully understand vlans. So you can just tag all the vlans to every port and then on each closet switch you can configure which ports goes in which vlan and configure the port to XSM with all the vlans.

I hope the above helps.
