# Multi-Router Implementation - Verification Status

**Last Updated**: 2026-06-19  
**Status**: ✅ COMPLETE - Ready for production testing

---

## Implementation Summary

### 1. Core Features Implemented

#### Smart Router Detection (`getEffectiveRouterId()`)
- **Location**: `services/customerService.js`
- **Mode: Aktif (Active Multi-Router)**
  - Returns customer's explicit `router_id` (can be NULL)
  - Customers MUST explicitly choose router during setup
  - Best for environments with multiple independent routers
  
- **Mode: Nonaktif (Single Router Fallback)**
  - Returns customer's `router_id` if set
  - Falls back to `default_router_id` setting if customer has NULL
  - Auto-detects first available router if no default set
  - Best for migration from single-router to multi-router
  - Allows old customers (NULL router_id) to work transparently

#### Router Connection Fallback (`getConnection()`)
- **Location**: `services/mikrotikService.js`
- Priority 1: Use specified `routerId` from database
- Priority 2: Auto-detect first active router from database
- Priority 3: Fallback to `settings.json` (backward compatibility)
- Includes TCP connectivity probing + cache (5s) for performance

#### Configuration
- **Location**: `settings.json`
- `multi_router_mode`: "active" | "disabled" (default: "disabled")
- `default_router_id`: Optional ID for fallback router

## Integration Points - All Verified

### ✅ Customer Suspension (Isolir)
**Admin Portal Route**: `POST /customers/:id/isolate`
- Calls `customerSvc.suspendCustomer(id)`
- Uses `getEffectiveRouterId()` internally
- Updates MikroTik profile → updates database status
- Sends WhatsApp notification to customer phone

**WhatsApp Bot Command**: `!isolir <customer_id>`
- Calls `customerSvc.suspendCustomer(id)`  
- Same multi-router support as admin route

**Code Flow**:
```
Admin/Bot Request
  → suspendCustomer(id)
    → getCustomerById(id)
    → getEffectiveRouterId(customer.router_id)
    → mikrotikSvc.setPppoeProfile() [respects effectiveRouterId]
    → updateCustomer() [database update]
    → sendWA() [notification]
```

### ✅ Customer Activation  
**Admin Portal Route**: `POST /customers/:id/unisolate`
- Calls `customerSvc.activateCustomer(id)`
- Uses `getEffectiveRouterId()` internally
- Updates MikroTik profile → updates database status

**Code Flow**:
```
Admin Request
  → activateCustomer(id)
    → getCustomerById(id)
    → getEffectiveRouterId(customer.router_id)
    → mikrotikSvc.setPppoeProfile() [respects effectiveRouterId]
    → updateCustomer() [database update]
```

### ✅ Payment Processing Integration
**Payment Service**: Routes at `/voucher-payment`, payment callbacks
- Customer payment → `activateCustomer()` → multi-router support
- Files: `services/paymentService.js`, `routes/voucherPaymentAPI.js`

### ✅ Export/Import Functionality
**Admin Portal Routes**: `GET /customers/export`, `POST /customers/import`
- Export includes `Router` column (maps to `router_name`)
- Import supports both old files (NULL router) and new (router specified)
- Backward compatible with existing export files
- File: `routes/adminPortal.js` (lines 1900-2000)

### ✅ Portal Login Support

**Customer Portal** (`routes/customerPortal.js`)
- PPPoE profile loading: Supports multi-router ✅
- Queries include `r.name as router_name` join
- Router filter applied by customer's effective router

**Tech Portal** (`routes/techPortal.js`)
- PPPoE profiles with router query param support ✅
- Route: `/tech/pppoe-profiles?routerId=1`
- Validates customer matches requested router

**ACS Portal** (`routes/acsPortal.js`)
- PPPoE profile loading for ONU management ✅
- Respects customer's effective router

### ✅ Connection Types - All Supported

| Connection Type | Suspend Implementation | Activate Implementation | Router Validation |
|---|---|---|---|
| **PPPoE** | `setPppoeProfile(username, 'isolir', routerId)` | `setPppoeProfile(username, profileName, routerId)` | Required for isolir ✅ |
| **Static IP** | `manageStaticIp({...isolate: true}, routerId)` | `manageStaticIp({...isolate: false}, routerId)` | Required ✅ |
| **Hotspot** | `setHotspotUserDisabled(user, true, routerId)` | `upsertHotspotUser({...disabled: false}, routerId)` | Required ✅ |

## Testing Checklist

### Phase 1: Basic Multi-Router Operations
- [ ] **Test 1.1**: Suspend customer with explicit router_id (Router 1)
  - Expected: Isolir works, customer can see they're suspended
  - Check: Database status = "suspended", WhatsApp notification received

- [ ] **Test 1.2**: Suspend customer with NULL router_id in "disabled" mode
  - Expected: Falls back to first router in database
  - Check: Customer isolir works even though router_id = NULL

- [ ] **Test 1.3**: Activate customer from suspended state
  - Expected: Customer can reconnect, service restored
  - Check: Database status = "active", PPPoE profile changed back

### Phase 2: Different Connection Types
- [ ] **Test 2.1**: Suspend customer with Static IP connection
  - Expected: IP rate-limited to isolir profile
  - Check: MikroTik queue rules applied

- [ ] **Test 2.2**: Suspend customer with Hotspot connection
  - Expected: Hotspot user disabled = true
  - Check: Customer cannot login to hotspot

### Phase 3: WhatsApp Bot Integration
- [ ] **Test 3.1**: Run `!isolir <customer_id>` command via WhatsApp
  - Expected: Customer isolir works, admin gets response
  - Check: Admin receives ✅ confirmation in WhatsApp

- [ ] **Test 3.2**: Run on customer with NULL router_id
  - Expected: Uses fallback router, works correctly
  - Check: Customer gets isolir'd despite NULL router

### Phase 4: Payment & Auto-Isolir
- [ ] **Test 4.1**: Customer makes payment after isolir
  - Expected: Auto-activates via payment webhook
  - Check: Customer service restored immediately

- [ ] **Test 4.2**: Auto-isolir on missed payment (cron job)
  - Expected: Customers automatically suspended on isolir_day
  - Check: Log shows "Auto-isolir" entries

### Phase 5: Export/Import Cycle
- [ ] **Test 5.1**: Export customers, verify "Router" column present
  - Expected: CSV has "Router" column with router names
  - Check: Column exists in exported file

- [ ] **Test 5.2**: Modify export, re-import with different router
  - Expected: Customer router_id updated in database
  - Check: New router_id reflected in customer edit view

### Phase 6: Mode Switching (Aktif ↔ Nonaktif)
- [ ] **Test 6.1**: Switch from "Nonaktif" → "Aktif"
  - Expected: Mode changes, no auto-assignments (existing customers keep current router)
  - Check: Settings updated, app doesn't crash

- [ ] **Test 6.2**: Switch from "Aktif" → "Nonaktif"
  - Expected: Mode changes, customers without router_id get assigned default
  - Check: Auto-assignment completed, NULL router_id → router_id populated

## Troubleshooting Guide

### Symptom: Customer suspendsion not working
**Check 1**: Verify customer has router_id set
```bash
SELECT id, name, router_id, pppoe_username FROM customers WHERE id = ?
```
- If NULL: Check multi_router_mode setting - must be "disabled" for fallback to work
- If not NULL: Verify router exists and is active

**Check 2**: Verify MikroTik connectivity
```bash
node -e "const m = require('./services/mikrotikService'); m.checkConnection(1).then(ok => console.log('Router 1:', ok))"
```

**Check 3**: Check application logs
```bash
tail -f logs/combined.log | grep -i "isolir\|suspend"
tail -f logs/error.log
```

### Symptom: WhatsApp isolir command fails
**Check**: Verify WhatsApp is enabled and logged in
- Check `settings.json`: `whatsapp_enabled: true`
- Check logs for "whatsapp" entries
- Verify phone number is in `whatsapp_admin_numbers`

### Symptom: Mode switching doesn't auto-assign routers
**Check**: Review logs during mode switch
```bash
grep -i "auto" logs/combined.log
```
- Should see messages about finding default router
- Verify at least one router has `is_active = 1`

## Next Steps

1. **Run Phase 1-3 Tests** on staging environment with multiple routers
2. **Verify WhatsApp bot** works with multi-router customers
3. **Test payment** auto-activation with mixed router customers
4. **Monitor logs** for any connection errors during testing
5. **Deploy** to production after all tests pass

## Rollback Plan

If issues occur in production:
1. Set `multi_router_mode: "disabled"` in `settings.json` 
2. Set `default_router_id` to the ID of your primary router
3. Restart application with `pm2 restart all`
4. All NULL router_id customers will automatically use the default router
5. Existing operations continue working (backward compatible)
