Port Based Address Allocation DHCP not Assigning Addresses

CarsonEdwards

I am setting up a new out of band switch with port based address allocation to help with an automation project. 

I thought I had everything correct, but the dhcp server (the switch) is not assigning addresses. 

My config is pretty short, but very repetitive.

 

I have included a .txt file to shorten up this post.

 

THANK YOU THANK YOU.

Hi,

In my view the interface short name is case sensitive. Can you please try to adjust your pool configuration accordingly, eg.:

address 10.10.10.1 client-id "Gi1/1" ascii

and see if that makes any difference.

Best regards,

Antonin

Hello

At first glance remove the following from the access- ports

ip dhcp server use subscriber-id client-id

Also the access-ports are currently assigned to vlan 1 but you don’t have any L3 address for that vlan and the only l3 address you do have isn’t the same as the dhcp scope!

dhcp -10.10.10.0/26
vlan 666 - 172.30.1.0/24

access-port
int x/x
switchport host
swithport access vlan x

DHCP is now assigning IPs, but it is assigning random IPs

I followed these instructions http://packetpros.com/per-port-ip-address-assignment/

 

I tried using a capital Gi1/1 but the configuration changes it back to gi1/1

 

THANK YOU!

I will give this ago shortly.

Hi,

Thanks for the reply. I have checked the configuration in my lab and my box keeps the commands as configured, ie. maintaining the case sensitivity. What you are experiencing may be an indication of a bug, so you may consider to upgrade.

I have always used the short interface name, not the full name in this case.

Best regards,

Antonin

THANK YOU folks,

address 10.10.10.1 client-id "Gi1/1" worked!

I guess starting over with a no ip dhcp pool pool1, helped me get the syntax right.

 

Thanks again!
