Have a network in an industrial plant that we use DHCP port-allocation on our switches, mainly 2950's that has been working great for the past couple of years. Maintenance can just replace a device and it will automatically receive all the information it needs after being connected and powered up.
Now we are installing a network monitoring device, where I've had the great fun of tying all the VLANs to a management switch (Cisco 3560) using ip routing and a few ACL's to keep the VLANs from communicating with each other.
In order to keep things simple for maintenance, it is now required to have a default gateway on these devices in order for them to communicate across the VLANs to the management VLAN, where the network monitor is hooked in.
I can't seem to find a way to assign a default gateway through DHCP port-allocation, or if it's even possible. Am I chasing a pipe dream? Or do I need to just assign the default gateway manually after the device is replaced and alerts on the network monitor?
The network monitor is a Panduit IntraVue Server (part# PNPIV).
Edit: There is not actual router on this network, never will be, our corp. IT will come and murder us. Our controls network is seperated by firewall to the corp network. We mostly control the controls network while corp. IT controls the firewall and above.
