VLANs/ Subnets help

[Geoff]

It's a shame that when using Windows DHCP you can't put clients in scopes based on vendor class or network interface, like you can with ISC DHCP.

Maybe one day when Cisco rules the world it may become the standard of all things but until then ..........

Errr no. ISC is the Internet Software Consortium. Their version of DHCP is the approved reference implementation as defined per the RFCs and the IETF.

Whats the proprietry method used by Cisco Switches for DHCP routing then....


my wires are proper crossed --> It's a monday thing !

How about an IPConfig /setclassid

It's called a DHCP Relay Agent and there's nothing proprietary about it.

That doesn't help. With Windows DHCP Server that only allows you to define per device/class DHCP options. Not put them in an entirely separate scope.

@j17sparky - How do you mean on the same subnet? Do you use reserved ips in DHCP to achieve this in their scope and does it work well? Were running parsql and need to get some speed here as taking 35 registers at one time slows thiongs down.

We just have one physical network. Admin have 192.168.1.1-127 and curriculam have 192.168.1.128-254 (for example)

Admin only have a dozen machines so are set up with statics within their defined scope. DHCP does the curriculam and just chooses IPs out of its scope.

All works fine. 100ish people logged into SIMS at once and ive not had anyone complain about the network being slow, SIMS yes as its a pile of **** but our network is perfectly fine as it is; All main branchs 1gb fibre, servers 1gb, clients 100mb, minor branchs 100mb, all HP procurve switches (well mostly)

By having a vLan you could actually increase traffic as you could be sending it round the houses (in order to change vlan) where as otherwise it could have taken a direct route. (Obviously depending on your physical layout)
