Link Aggregation Control Protocol (LACP) is widely used in ISP and enterprise networks to combine multiple physical links into a single logical interface. In this complete guide, you will learn how to configure LACP between a MikroTik Router and a C-DATA OLT step by step. This setup helps achieve higher bandwidth, redundancy, and better network stability. What is LACP and Why It Is Important?LACP (IEEE 802.3ad) allows multiple Ethernet links to work together as one bonded interface. Instead of relying on a single uplink cable, ISPs use LACP to increase total throughput and ensure failover protection. If one cable fails, traffic automatically shifts to the remaining active links without service interruption. In ISP environments, especially when connecting MikroTik routers with OLT devices like C-DATA, LACP ensures stable upstream connectivity and balanced traffic distribution across links. Step 1: Check MikroTik RouterOS CompatibilityBefore starting the configuration, ensure that your MikroTik router is running a RouterOS version that supports bonding and LACP. Both RouterOS v6 and v7 support 802.3ad bonding. It is recommended to update to the latest stable version to avoid bugs and compatibility issues. Also verify that the Ethernet interfaces you plan to use are not already assigned to other bridges or configurations. Step 2: Create LACP Bonding Interface on MikroTikNow you need to create a bonding interface on the MikroTik router using LACP mode. This bonding interface will combine multiple Ethernet ports into one logical interface. /interface bonding add name=LACP-C-DATA-OLT mode=802.3ad slaves=sfp-sfpplus2,sfp-sfpplus4 transmit-hash-policy=layer-2-and-3 disabled=no The 802.3ad mode enables LACP, while the transmit-hash-policy ensures better traffic distribution. The lacp-rate=1sec option helps detect link failure faster. Step 3: VLANs Creation on Mikrotik RouterNow we will create multiple VLANs on top of the bonding interface. Since my OLT has 4 physical ports, we will create a total of 5 VLANs: 1 VLAN will be used for OLT managementThe remaining 4 VLANs will be used to access and operate the PON ports. This setup allows us to properly manage the OLT and distribute traffic through each PON port efficiently. We are creating VLANs ranging from 500 to 504. VLAN 500 is reserved for OLT management. We will assign a management IP on VLAN 500 to access and manage the OLT.The remaining VLANs will be used for the OLT PON ports.So, let’s get started. /interface/bondingadd interface=LACP-C-DATA-OLT name=C-DATA-EPON-1 vlan-id=201add interface=LACP-C-DATA-OLT name=C-DATA-EPON-2 vlan-id=202add interface=LACP-C-DATA-OLT name=C-DATA-EPON-3 vlan-id=203add interface=LACP-C-DATA-OLT name=C-DATA-EPON-4 vlan-id=204add interface=LACP-C-DATA-OLT name=C-DATA-MGMT vlan-id=200 Step 4: Configure LACP on C-DATA OLTNext, log in to the C-DATA OLT via CLI and configure LACP on the corresponding uplink ports. The exact commands may vary slightly depending on the C-DATA model and firmware version, but the logic remains the same. ** EPON OLT Integrated Operating System. **** Device Model : FD1208S **** Hardware version : V3.0 **** Firmware version : V1.6.0_241021 **** BuildDate : Mon, 21 Oct 2024 18:43:08 +0800 **** Mac Address : E0:67:B3:7A:0D:F1 ** OLT> enableOLT# configOLT(config)#OLT(config)# interface link-aggregationOLT(config-interface-aggregation)# member add xge 0/0 1,2 link-aggregation group 10OLT(config-interface-aggregation)# vlan mode 10 trunkOLT(config-interface-aggregation)# vlan trunk 10 200-204OLT(config-interface-aggregation)# exitOLT(config)# save The percentage of saved data is: 0% The percentage of saved data is: 2% The percentage of saved data is: 5% The percentage of saved data is: 8% The percentage of saved data is: 11% The percentage of saved data is: 14% The percentage of saved data is: 17% The percentage of saved data is: 20% The percentage of saved data is: 23% The percentage of saved data is: 26% The percentage of saved data is: 29% The percentage of saved data is: 32% The percentage of saved data is: 35% The percentage of saved data is: 38% The percentage of saved data is: 41% The percentage of saved data is: 44% The percentage of saved data is: 47% The percentage of saved data is: 68% The percentage of saved data is: 81% The percentage of saved data is: 95% The percentage of saved data is: 100% OLT(config)# Here, the mode active command enables LACP negotiation. Both MikroTik and C-DATA must use active LACP mode to properly establish the aggregated link. Step 5: Verify LACP Status on MikroTikOnce both sides are configured, you should verify the LACP status on the MikroTik router. This confirms whether the links are successfully aggregated. /interface bonding monitor LACP-C-DATA-OLT If the configuration is correct, you will see all slave interfaces listed as active. If any port shows inactive status, double-check cabling and configuration on both ends. Step 6: Verify LACP Status on C-DATA OLT On the C-DATA OLT, use verification commands to confirm that the LACP group is up and running. This helps ensure that traffic is properly balanced across all member links. OLT(config)# show link-aggregation group summaryYou should see the channel group in an active state with all member ports bundled correctly. Best Practices for ISP Networks For ISP environments, always use high-quality cables and identical port speeds on both sides of the LACP link. Mixing different speeds can cause unstable behavior and performance issues. Regularly monitor LACP status and traffic statistics to ensure links are functioning optimally. This proactive approach helps prevent downtime and customer complaints. Conclusion Configuring LACP between a MikroTik router and a C-DATA OLT is an essential step for building a high-availability and high-performance ISP network. By following this complete step-by-step guide, you can ensure reliable uplink connectivity, automatic failover, and efficient bandwidth utilization. If you manage ISP or enterprise networks, mastering LACP configuration will significantly improve your network stability and scalability.

Step 1: OLT AccessWhen a network device needs to be configured, the first step is to log in to that device. Today we will fully configure Vsol OLT. We need to log in to OLT first. We can access OLT mainly in 2 ways. One is the AUX port and the other is the console port. Today we will configure OLT by accessing OLT through AUX Port. Accessing OLT by AUX Port: If you want to access your Vsol epon olt using by AUX port then first you need to an ethernet cable(RJ45). then your need to connect the ethernet cable to pc to the olt AUX port. Do you know that vsol epon olt has a fixed static IP address for the AUX port? The AUX port IP address is 192.168.8.100 and the subnet is 255.255.255.0. If you want to access your olt by using the AUX port then you need to change your pc lan IP address using the same subnet mask. so now we change our pc IP to 192.168.8.101 and the subnet mask is 255.255.255.0. Hey, Buddy now we can access our Vsol OLT via telnet (192.168.8.100) or web management https://192.168.8.100. This address is the default VLAN interface address of the OLT.

That means 4 pon ports and 4 different VLAN interfaces. So now we are creating the VLAN in our OLT. Our uplink port is G1 and let’s start creating VLANs. Username:admin Password: Xpon@Olt9417# epon-OLT> ena Password: Xpon@Olt9417# epon-OLT#configure terminal epon-OLT(config)# epon-OLT(config)# vlan 400 – 404 epon-OLT(config)# exit Our VLANs (400 – 404) was successfully created and now we can use these VLANs for service. So we will be using VLAN 400 for olt MGT (remote management) and VLAN 401 to 404 for pon port. Now we are configuring our uplink as G1 epon-OLT(config)# interface gigabitethernet 0/1 epon-OLT(config-if-ge0/1)# switchport mode trunk epon-OLT(config-if-ge0/1)# switchport trunk vlan 400 – 404 epon-OLT(config-if-ge0/1)# exit Our uplink port G1 is successfully trunk or tag configured with VLANs. Now we can check the mac address in the VLAN interface. You need to follow the command below to view the mac address. epon-OLT(config)# show mac address-table interface gigabitethernet 0/1 Step 3: IP address assignedWe can access OLT from our LAN side. It needs to assign an IP address. through which the OLT will be accessed. So let’s assign an IP to VLAN 400 for olt MGT (remote management) access using the below command. epon-OLT(config)# interface VLAN 400 epon-OLT(interface-vlan-200)# ip address 10.100.100.2 255.255.255.252 epon-OLT(interface-vlan-200)# exit epon-OLT(config)# ip route 0.0.0.0/0 10.100.100.1 Step 4: Pon Port ConfigureNow we need to configure the PON port. We have created 4 VLANs for 4 PON ports.so let’s start, PON- 1 epon-OLT(config)# interface epon 0/1 epon-OLT(config-pon-0/1)# switchport mode access epon-OLT(config-pon-0/1)# switchport access VLAN 401 epon-OLT(config-pon-0/1)# exit PON- 2 epon-OLT(config)# interface epon 0/2 epon-OLT(config-pon-0/2)# switchport mode access epon-OLT(config-pon-0/2)# switchport access VLAN 402 epon-OLT(config-pon-0/2)# exit PON- 3 epon-OLT(config)# interface epon 0/3 epon-OLT(config-pon-0/3)# switchport mode access epon-OLT(config-pon-0/3)# switchport access VLAN 403 epon-OLT(config-pon-0/3)# exit PON- 4 epon-OLT(config)# interface epon 0/4 epon-OLT(config-pon-0/4)# switchport mode access epon-OLT(config-pon-0/4)# switchport access VLAN 404 epon-OLT(config-pon-0/4)# exit

BDCOM EPON OLT default ip: IP Address: 192.168.0.1Username: adminPassword: admin OLT Login Access: OLT Access can be done in 2 ways. One is through a console cable and the other is through an ethernet cable. OLT Access via Console Cable: Every networking device must have a console port.BDCOM Epon 4,8,16 port OLT has console port together. First console connectivity from PC to OLT should be done. A converter will be required for connectivity. The name of that is Serial to USB converter.CLI mode is the most comfortable system to configure OLT. if you want o configure your olt with CLI mode then you need to use software like Putty, and one thing is to make sure to select speed 9600. OLT Access via Ethernet Cable: If you want you can access OLT through an Ethernet cable. One side of the Ethernet cable should be connected to the PC, and the other side can be connected to any Ge port of the OLT, like Ge1, or Ge2. After establishing Ethernet connectivity, OLT can be accessed by opening CLI mode with OLT’s default IP. BDCOM Epon olt default IP address is 192.168.0.1 and the subnet is 255.255.255.0. so now we need to change our PC’s IP to 192.168.0.10 and the subnet is 2555.255.255.0. Finally, we can access our olt via telnet (192.168.0.1) or web management 192.168.0.1. VLAN Creation: Username: admin Password: admin Switch>enable Switch#config Switch_config# Switch_config# vlan 100 – 104 Switch_config# exit Our VLANs (100 – 104) were successfully created and now we can use these VLANs for service. So we will be using VLAN 100 for Olt MGT (remote management) and VLAN 101 to 104 for Pon port. Uplink Configure: Now we are configuring our uplink as G3 Switch_config# interface gigabitethernet 0/3 Switch_config_g0/3# switchport mode trunk Switch_config_g0/3# switchport trunk VLAN 100 – 104 Switch_config_g0/3# exit Our uplink port G3 is successfully trunk configured with VLANs.
