LANCOM XS-6128QF

The stacking feature keeps your network flexible and your investment secure. Stacking makes child’s play of expanding your network, as several physical switches combine into a single logical unit for convenient maintenance and management. When you expand your network, the new switch automatically receives a configuration from the stack master and is ready to use within seconds. Furthermore, device or network redundancies can be implemented with stacking for maximum reliability. With the LANCOM XS-6128QF, stack processing with a separate backplane CPU remains independent of network load thanks to four dedicated SFP-DD-FleX ports (50G).

Virtual Port Channel (VPC), or Multi-chassis Link Aggregation Group (MC-LAG), is the preferred solution for increasing the reliability of large network infrastructures. If you link two LANCOM XS-6128QF in a VPC network, one of the two devices takes over the tasks of the other device without interruption in the event of a defect or failure, e.g. during a firmware update. To ensure constant data forwarding, the switches exchange important information about the network via their peer link, such as MAC tables and routing information. For 100% network uptime, the switches remain independently manageable devices that can be restarted or updated individually.

The LANCOM XS-6128QF is an ideal aggregation instance for the networking of access switches. Depending on the size of the installation, it integrates into the network topology either on the top level as core switch facing the WAN (2-tier design) or on the second level as distribution switch between a core switch and the access switches (3-tier design).

The design concept of the LANCOM XS-6128QF provides for a very low total cost of ownership (TCO), because all ports are natively available, which saves a costly modular design. So this aggregation switch enables all maximum port options out of the box with combo downlink (copper/fiber) and combo uplink (25G/40G) fiber ports. All ports are industry standard, even for stacking, so there is no need for costly proprietary cables. For example, there is the option of using SFP+ modules in the 4x 25G SFP28 ports for up to 4 additional SFP+ ports. Decentralized stacking thanks to the possibility of using standard short and long range modules is also possible with this model.

The LANCOM XS-6128QF is capable of performing layer 3 tasks such as DHCP server functionality, i.e. IP address management, or the predefinition of network routes across one or more network segments. Thanks to dynamic routing, the switch can also react quickly to network changes. The optimal route for data traffic within the network is thus constantly redefined by the LANCOM XS-6128QF based on the load level. This results in a load reduction on the router, so that these capacities are then additionally available for handling external data traffic and increase the efficiency of the entire network.

The LANCOM XS-6128QF can be operated with up to twohot-swappable PSUs (power supply units). This allows a quick and uninterrupted replacement of defective power supply units. Front-to-back airflow design with swappable fans improves cooling in 19-inch racks and extends the product lifetime. Stacking is a major contribution to highly resilient scenarios.

With the LANCOM Management Cloud, the XS-6128QF offers quick and easy network integration as well as automatic provision of the configuration across locations with the a click of a mouse. Cloud-managed LAN replaces the configuration of individual devices and enables automatic assignment of VLANs to switch ports. Cloud-managed switch stacking also enables convenient management and monitoring of the entire stack.

This function provides access to the command line of the LANCOM switch ("CLI tunneling") directly from the LANCOM Management Cloud—encrypted and without leaving the cloud interface. Be it trace or ping commands for rapid troubleshooting, access to low-level configuration parameters and detailed statistics in the LCOS SX operating system, or secure remote access to third-party devices in the local network via the integrated SSH client—Secure Terminal Access offers expert functions and extensive diagnostic and troubleshooting commands on your devices.
