# Network Infrastructure Management

Comprehensive management tools for network infrastructure including switches, routers, VLANs, and network topology.

## Overview

This directory contains management components for network infrastructure across Sankofa Phoenix sites, including:

- **Switches**: Configuration management for network switches
- **Routers**: Router configuration and routing protocol management
- **VLANs**: VLAN configuration and tracking
- **Topology**: Network topology discovery and visualization

## Components

### Switches (`switches/`)

Switch management tools for:
- VLAN configuration
- Port configuration
- Trunk/LAG setup
- STP configuration
- Port security
- SNMP monitoring

### Routers (`routers/`)

Router management tools for:
- Routing table management
- BGP/OSPF configuration
- Firewall rules
- NAT configuration
- VPN tunnels
- Interface configuration

### VLANs (`vlans/`)

VLAN management for:
- VLAN creation and deletion
- VLAN assignment to ports
- VLAN trunking
- Inter-VLAN routing
- VLAN tracking across sites

## Usage

### Switch Configuration

```bash
# Configure switch VLAN
./switches/configure-vlan.sh \
  --switch switch-01 \
  --vlan 100 \
  --name "Employee-Network" \
  --ports "1-24"

# Configure trunk port
./switches/configure-trunk.sh \
  --switch switch-01 \
  --port 25 \
  --vlans "100,200,300"
```

### Router Configuration

```bash
# Configure BGP
./routers/configure-bgp.sh \
  --router router-01 \
  --asn 65001 \
  --neighbor 10.0.0.1 \
  --remote-asn 65000

# Configure OSPF
./routers/configure-ospf.sh \
  --router router-01 \
  --area 0 \
  --network 10.1.0.0/24
```

### VLAN Management

```bash
# Create VLAN
./vlans/create-vlan.sh \
  --vlan 100 \
  --name "Employee-Network" \
  --description "Employee network segment"

# Assign VLAN to switch port
./vlans/assign-vlan.sh \
  --switch switch-01 \
  --port 10 \
  --vlan 100
```

## Network Topology

### Discovery

```bash
# Discover network topology
./discover-topology.sh --site us-east-1

# Export topology
./export-topology.sh --format graphviz --output topology.dot
```

### Visualization

Network topology can be visualized using:
- Graphviz
- D3.js
- React Flow (in Portal)

## Integration with Omada

Network management integrates with TP-Link Omada for:
- Unified network policy management
- Centralized VLAN configuration
- Network analytics

See [Omada Management](../omada/README.md) for details.

## Configuration

### Switch Configuration

```yaml
switches:
  - name: switch-01
    model: TP-Link T1600G
    ip: 10.1.0.1
    vlans:
      - id: 100
        name: Employee-Network
        ports: [1-24]
      - id: 200
        name: Guest-Network
        ports: [25-48]
    trunks:
      - port: 49
        vlans: [100, 200, 300]
```

### Router Configuration

```yaml
routers:
  - name: router-01
    model: TP-Link ER7206
    ip: 10.1.0.254
    bgp:
      asn: 65001
      neighbors:
        - ip: 10.0.0.1
          asn: 65000
    ospf:
      area: 0
      networks:
        - 10.1.0.0/24
        - 10.2.0.0/24
```

### VLAN Configuration

```yaml
vlans:
  - id: 100
    name: Employee-Network
    description: Employee network segment
    subnet: 10.1.100.0/24
    gateway: 10.1.100.1
    dhcp: true
    switches:
      - switch-01: [1-24]
      - switch-02: [1-24]
  
  - id: 200
    name: Guest-Network
    description: Guest network segment
    subnet: 10.1.200.0/24
    gateway: 10.1.200.1
    dhcp: true
    isolation: true
```

## Monitoring

Network monitoring includes:
- SNMP monitoring for switches and routers
- Flow monitoring (NetFlow/sFlow)
- Network performance metrics
- Topology change detection

See [Monitoring](../monitoring/README.md) for details.

## Security

- Network segmentation via VLANs
- Port security on switches
- Firewall rules on routers
- Network access control
- Regular security audits

## Troubleshooting

### Common Issues

**Switch connectivity:**
```bash
./switches/test-connectivity.sh --switch switch-01
```

**VLAN issues:**
```bash
./vlans/diagnose-vlan.sh --vlan 100
```

**Routing problems:**
```bash
./routers/diagnose-routing.sh --router router-01
```
