host declaration: Either hardware or dhcp-client-identifier will always match, but never both?

[Harald A. Irmer]

Hi,

I'd like to have a host declaration thus:

host nb2-smith {
hardware 00:11:22:33:44:55;
option hostname "nb2-smith";
option dhcp-client-identifier "smith\nb2@vlan111";
...
}

Why this?:

Two concurrent independent uses:

1. User Smith connects with his notebook and gets the static lease
dependent on its hardware address, "00:11:22:33:44:55"; the notebook
will NOT send the client identifier "smith2\nb2@vlan111"; we will assume
that the notebook sends a client identifier which is DIFFERENT TO
"smith2\nb2@vlan111".

2. User Smith's notebook is not connected to its vlan but is going to
set up a vpn connection from outside; the multiple VLAN vpn server with
delegated address management (yes there's one!) then send's a
DHCP-Request with the client identifier "smith2\nb2@vlan111"; for sure
the vpn server's hardware address is DIFFERENT TO 00:11:22:33:44:55.


Will this work, that either hardware or dhcp-client-identifier will
always match, but never both the same time?


Yours,

Harald

Forgot to add: for ip economy we'd like to use the same ip - one host
declaration - for both usages, i.e. the line "fixed-address
[hidden email]" should be added.
