Bond IP to Mac address

 

Protocol Address          Age (min) Hardware Addr      Type Interface

Internet  155.237.221.37          0 0080.a3d0.c298     ARPA Vlan2

 

 

Hi,

Few months ago I did request an IP to be assigned to a device to monitor and control room temperature at one of our Server Rooms. I had to provide its mac address as well

This might sound like a stupid question: How do you statically assign it? The task was completed by one of our senior LAN engineers (busy guy…I wish he had the time to explain to me)

 

When i run the show ip 155.237.221.37 i get it connected to interface VLAN2. in order to find the physical interface i issued the show mac address-table address 155.237.221.37 command and from there, issued the show cdp neighbors to find out which switch it connects to (WS-C2960)

 

 

Output from our Router 

ip dhcp pool MAPBIN

network 155.237.221.0 255.255.255.128

default-router 155.237.221.1

domain-name yyy.xxxl.com

dns-server 10.193.8.53 155.237.252.24

lease 0 8

 

interface Vlan2

ip address 155.237.221.1 255.255.255.128

no ip redirects

no ip unreachables

no ip proxy-arp

end

The actual settings for the Temperature monitor device are:

IP:155.237.221.37

Mask: 255.255.255.128

GW: 155.237.221.1 

I could see the default router points to interface VLAN 2 IP address

My assumption is: all devices connected to ports that are member of VLAN 2 will get their IPs from MAPBIN pool

 

Bottom line is: how do i bond this IP to the given Mac address 00080.a3d0.c298?

Example:

ip dhcp pool static-host
host 155.237.221.37 255.255.255.0
client-identifier 0100.80a3.d0c2.98   ( 01 extension added to mac add of client)
default-router 155.237.221.1
domain-name yyy.xxxl.com
dns-server 10.193.8.53 155.237.252.24
lease 0 8
