Static ip binding with mac address not working in cisco 1117 router

[r4rehan11]

Hi I am trying to bind three ip addresses with three mac addresses but they are not showing active on vlan 1 

The config is as follows 

ip dhcp pool d461.9d08.771e
host 10.31.2.151 255.255.255.0
client-identifier d461.9d08.771e //Add 01 as client-identifier 01d4.619d.0877.1e
default-router 10.31.1.1
dns-server 10.250.17.111 10.250.21.20510.31.2.210 b0be.831a.5483 Infinite Manual Selecting Unknown

domain-name aero.care

ip dhcp pool b0be.831a.5483
host 10.31.2.210 255.255.255.0

client-identifier b0be.831a.5483
default-router 10.31.1.1
dns-server 10.250.17.111 10.250.21.205
domain-name aero.care

ip dhcp pool e0ac.cb76.7fcc
host 10.31.2.152 255.255.255.0
client-identifier e0ac.cb76.7fcc //Add 01 client-identifier 01e0.accb.767f.cc

default-router 10.31.1.1
dns-server 10.250.17.111 10.250.21.205
domain-name aero.care

=============================
ip dhcp excluded-address 10.31.2.151 10.31.2.152
ip dhcp excluded-address 10.31.2.210

I have aslo performed clear ip dhcp binding 10.31.2.151
clear ip dhcp binding 10.31.2.210
clear ip dhcp binding 10.31.2.152 

but the output for three ip showing is like this 

10.31.2.210 b0be.831a.5483 Infinite Manual Selecting Unknown

10.31.2.151 d461.9d08.771e Infinite Manual Selecting Unknown
10.31.2.152 e0ac.cb76.7fcc Infinite Manual Selecting Unknown

Kindly assist in this matter on urgent basis ?

DHCP reservation :

lient-identifier unique-identifier Example: Router(dhcp-config)# client-identifier 01b7.0813.8811.66

Specifies the unique identifier for DHCP clients. This command is used for DHCP requests. • DHCP clients require client identifiers. The unique identification of the client is specified in dotted hexadecimal notation, for example, 01b7.0813.8811.66, where 01 represents the Ethernet media type.

example :

client-identifier 01d4.619d.0877.1e

Also have observed default router in different subnet - is this typo or intention ?

default-router 10.31.1.1

where is this IP residing?  ( can you post show IP interface brief) or change 10.31.2.x

where is the gateway for 10.31.1.X  - or Layer 2 interface for the route to take place?

how is your network diagram looks like ?

you need to change the DHCP pool to inline with you VLAN 1

that is 10.31.1.X network.

if this only device you have in the network you need to change the DHCP pool as below :

ip dhcp pool LAN2
network 10.31.1.0 255.255.255.0
default-router 10.31.1.252 ( based on the information you provided VLAN1 has this IP address)
dns-server 10.250.17.111 10.250.21.205
domain-name aero.care

Note : make sure you exclude router gateway address from DHCP pool.

Kindly provide a valid solution without changing the gateway address

let me explain the issue here, 
let assume you config many DCHP pool in one R/SW

how R/SW know to assign this IP from this DHCP Pool ??
it match the interface receive the DHCP request with the default router you config, if not then it mathc interface with DHCP Pool network 
you here break this role by assign default router different than the DHCP Pool network. 
so change the default router and try.
