PT, assigning IP to switch using DHCP via router

[kalafijoras]

Topology:   Router --> Switch --> 2 VLANs. I configured the router as DHCP server to give different IPs to different VLANs. How can I configure router to assign ip address dynamicly by its MAC address.

I was using this for VLANs:

ip dhcp pool vlan12

network xxx.xxx.x.x 255.255.255.0

default-router xxx.xxx.x.x

exit

ip dhcp excluded-address .....

What should I use for the switch?

I have found and didnt work:

hardware-address *MAC*

Thank you.

Hello, Unfortunately - there is no option to create reservations in DHCP in PT - its a limitation.

You may wish you configure an ip address on the switch manually and have a default-gateway to the routers ip address.

hope this helps.

Hi,

still a limitation of PT which is very good for basic stuffs but is very limited in my humble opinion.

I know GNS3 is not endorsed by Cisco but if you can't afford to buy real material this is by far the best tool to learn and experiment.

Hi,

-you must look at the dynamic bindings to see the client-identifiers with sh ip dhcp binding command.

- clear the binding with clear ip dhcp binding x.x.x.x command

-configure the host pool with the client-identifier xxxxxx command with the identifier you got from the dynamic binding.

Hello Alain,

There is no option for this... Unless I was looking in the incorrect place?

ISP(dhcp-config)#?

  default-router  Default routers

  dns-server      Set name server

  exit            Exit from DHCP pool configuration mode

  network         Network number and mask

  no              Negate a command or set its defaults

  option          Raw DHCP options

Thats due to a limitation of PT.

Example, try the debug command, you will see you get two or three options, on a regular IOS you get tons.

As mentioned before, its good for basic stuff, but more advanced it can not handle.
