I saw a strange comment bagging IT departments (i.e. sysadmins) on Slashdot the other day:
half the time they cant even do a simple thing like provide a jack with a set IP address for us
Reading the DHCP specs, nothing obvious jumps out as supporting this, but (some?) Cisco switches offer a feature called "DHCP Server Port-Based Address Allocation" which achieves this; so can it be done by:
- VLANs and a VLAN-aware DHCP server?
- some special combination of DHCP options (option 82, relay agent information)?
- only proprietary solutions like specific Cisco switches?
This is largely theoretical (I don't need to implement it), but I'm curious as to how "simple" it really is. Could I do it with my existing HP Procurve 2524 & dnsmasq, would I need a more sophisticated DHCP server, or would I need a new Cisco switch too?
