DHCP Manual binding issue

Hi everyone,

I created a manual binding for my DHCP service but it never worked. It always receives the dynamic PI from its parent pool.

ip dhcp pool parentPool

network 10.1.1.0 255.255.255.0

default-router 10.1.1.254

dns-server 139.130.4.4 61.3.133.192

option 42 ip 128.250.36.2 128.250.36.3

!

ip dhcp pool manualPool

host 10.1.1.250 255.255.255.0

hardware-address 0010.4918.1225 ieee802

client-name myVoiceSwitch

I even tried to stop and start DHCP service again. Is there anything I missed?

Best regards,

Triet

Re: DHCP Manual binding issue

if the DHCP client is a Microsoft client, replace

the "hardware-address 0010.4918.1225 ieee802"

command with

"client-identifier 0100.1049.1812.25 " command where the first 01 represents

a media type of Ethernet.

Re: DHCP Manual binding issue

How do you define a Microsoft client? This is a ShoreGear switch (ShoreTel VoIP switch), I guess it is not Microsoft.

However I tried this option, doesn't work either.

Could you please advise another option?

Thank you

Re: DHCP Manual binding issue

Have you tried it without the ieee802 appended?

Re: DHCP Manual binding issue

Yes I have, with either "ieee802" and "ethernet" option.

I even reloaded the router just to be sure.

Re: DHCP Manual binding issue

Here is a static reservation config that works--just scrambled the names and numbers.

ip dhcp pool local-network-pool

import all

network 10.20.30.128 255.255.255.248

default-router 10.20.30.129

dns-server 10.20.20.10

domain-name not-real-domain.org

netbios-name-server 10.20.20.10

!

ip dhcp pool static-ip-for-device

host 10.20.30.130 255.255.255.248

hardware-address 0024.0d55.7c53

Re: DHCP Manual binding issue

I found the cause of the problem. In the config, there was an: ip dhcp excluded-address 10.1.1.150 10.1.1.255. And the address I tried to set is 10.1.1.250.

I always thought that those reserved IPs are for manual binding. Actually the manual binding is part of the DHCP server and it takes the excluded-address range into account as well.

Thank you very much for all your help. I really appreciate it.
