Before drill pads, there’s physics

Rumble Resources Inc uses IP and AMT surveys to identify electrical contrasts linked to intrusive centers and alteration zones

these contrasts often precede economic copper mineralization in porphyry systems.

🛑 VLAN vs VXLAN: the evolution of network segmentation

For decades, VLANs have been the standard for network isolation: simple, reliable, and widely adopted. But as networks grew, their limitations became evident.

Modern data centers avoid indefinitely extending Layer 2 https://t.co/apD4A8vu6Y

> Verifying VLAN status with show vlan

The show vlan or show vlan brief command answers two critical questions:
> Does the VLAN exist on this switch?
> Is the VLAN active or shut down?

VLANs appear in one of two key states:
> active → forwarding allowed

Visibility platforms improve control.
$RIME's SemiCab focuses on lane economics

What’s different:
Optimization around round-trip utilization
Direct reduction of empty miles
Revenue tied to lane count and freight volume, not user seats

Example: expanding to 20 core freight lanes https://t.co/VRnbZV2XwB

> How a switch learns VLANs

A VLAN can exist on a switch in only two ways:
> Manually configured using the vlan vlan-id command
> Learned dynamically through VTP

If a VLAN does not exist, the fix is simple: configure it locally.

No VLAN definition means no

> VLANs undefined or disabled

Switches do not forward frames for VLANs that:
> Do not exist on the switch, or
> Exist but are administratively shut down

If a VLAN is missing or disabled, traffic in that VLAN simply stops at the switch even if interfaces are
