High performance
IP Routing |
- Provides basic IP unicast routing protocol (static and RIPv1 and 2) support for small network routing applications
- Provide advanced IP unicast routing protocols (OSPF and BGPv4) for load balancing and building scalable LANs
- Support IP multicast routing PIM loose mode (PIM-SM)
- Support 256 switch virtual interfaces (SVI), all physical interfaces can be used as Layer 3 interfaces
- Proxy Address Resolution Protocol (ARP) allows answering ARP queries from network hosts
- The Gratuitous Address Resolution Protocol (ARP) assists in updating the ARP tables of other machines, and helps detect IP conflicts, and ensures load balancing of inbound traffic under certain circumstances
- Support IPv6 routing on hardware for maximum performance
- Virtual Routing Redundancy Protocol (VRRP) provides dynamic load balancing and failover functions for routed links
|
| Powerful multicast control |
- Internet Group Management Protocol (IGMP) monitoring function allows clients to quickly join or exit the multicast stream, limiting bandwidth-intensive video traffic to only the requester.
- IGMP Snooping function TCN provides the ability to quickly respond to topology changes, so that the service provider's multicast service will not be suspended due to topology changes.
- IGMP leave immediately covers the normal check to see if there are other hosts or proxy devices in the local network segment in the multicast group, and shorten the IPTV service time of changing channels.
- IGMP provides multicast identity authentication by filtering non-subscribers, and limits the number of concurrent multicast streams available on each port.
- The IGMP Proxy function enables the system to send out IGMP host information, which represents the standard
- The IGMP interface discovers the host of the system and allows any user on the downstream network to join the upstream source multicast group.
- Multicast VLAN Registration (MVR) allows a single multicast VLAN, which can improve bandwidth utilization by simplifying the sharing between different user VLANs on the multicast group management network.
- Source multicast group.
- Multicast VLAN Registration (MVR) allows a single multicast VLAN to simplify the multicast group
- The sharing of different user VLANs on the management network can improve bandwidth utilization.
|
| Bandwidth optimization |
- Port broadcast, multicast and unicast storm control can prevent faulty terminals from affecting the entire system.
- Equal-cost ECMP routing promotes L3 load balancing and redundancy.
- The switch port auto-recovery function attempts to reactivate the disabled link due to a network error.
- Up to 55 port aggregation groups, each group supports 16 member ports.

| Cyber security |
| Comprehensive security solution |
User safety:
- IEEE 802.1x can realize dynamic, port-based security and provide user identity authentication function
- DHCP monitoring can prevent malicious users from deceiving the DHCP server and sending forged addresses. This feature can also defend against many other attacks, such as ARP destruction, etc.
- Dynamic ARP inspection can prevent malicious users from using the insecure features of ARP to damage and ensure the integrity of user information
- IP source protection can create a binding list between the client's IP and MAC addresses, ports, and VLANs to prevent malicious users from spoofing or stealing another user's IP address
Switch security:
- Control plane security can prevent DoS attacks on the CPU
- SSH protocol provides network security by encrypting administrator traffic in Telnet and SNMP connections
- Port security can guarantee access to a certain access or aggregation port based on the MAC address.
- MAC address filtering, MAC address port binding, MAC address port restriction
- Multi-level security of console access can prevent unauthorized users from changing the switch configuration
- RADIUS authentication can centrally control the switch to prevent unauthorized users from changing the configuration
Cyber security:
- Software system standards and extended IP security router ACLs define second, third, and fourth security policies for control plane and data plane traffic on the routing interface
- ACL based on the second layer interface allows users to apply security policies to each switch port separately
- The BPDU protection device can close the port to avoid possible loops when receiving BPDUs on the STP Fast-enabled port
- DHCP monitoring prevents users from maliciously deceiving the DHCP server and sending fake addresses. This feature is often used by other security features to prevent attacks such as ARP destruction
- The dedicated VLAN can divide the Layer 2 traffic and transform the broadcast network into a non-broadcast network like multi-access, thereby restricting the data traffic to a certain network segment

| Manageability |
| Excellent manageability |
- H540-48X6Q routing switch provides a common user interface and command set
- IEEE 802.1ag connection fault management provides standard support functions for transmission fault management, and supports the discovery and verification of the second layer service path
- The second layer of route tracking can reduce the difficulty of troubleshooting by determining the physical path that a packet travels from the source to the destination
- NTP can provide accurate and unified time for all switches in the intranet
- FTP and TFTP can reduce the management cost of software upgrades by downloading upgrade software from a centralized location
- Dynamic Host Configuration Protocol (DHCP) relay allows a DHCP relay agent to broadcast DHCP requests to the network DHCP server.
- Port multi-function LED can display the port status, half-duplex and full-duplex mode, provide 10BASE-T, 100BASE-TX, 1000BASE-T, 10GBASE-LR port indication; switch-level status LED for system, redundant power supply and Bandwidth utilization provides a comprehensive and convenient visual management system.
