DHCP Snooping / DAI with MC-LAG

• DHCP Snooping and Dynamic ARP Inspection (DAI) are not intended to be used simultaneously with MC-LAG. Enabling these features in an MC-LAG environment may result in unexpected traffic forwarding behavior.

Dashboard

• Dashboard default as closed since QSS v4.4.2

New Features

Support for Command Line Interface (CLI)

• This update introduces a Command-Line Interface, allowing users to configure and manage the switch directly through text-based commands. User can access the CLI via SSH port 22 or through the console.

DHCPv4 Snooping

• This update adds DHCPv4 Snooping, a security feature that monitors DHCP traffic to prevent unauthorized DHCP servers from distributing invalid IP addresses. By classifying ports as trusted or untrusted, it protect the network against attacks such as DHCP spoofing.

IP Source Guard (IPSG)

• This update adds IP Source Guard, a security feature that restricts IP traffic on untrusted ports by filtering packets based on the DHCP Snooping binding table. Only traffic with a matching source IP and MAC address is permitted, preventing IP spoofing attacks on the network.

Dynamic ARP Inspection (DAI)

• This update adds Dynamic ARP Inspection, a security feature that validates ARP packets against the DHCP Snooping binding table. It intercepts and discards ARP packets with invalid IP-to-MAC address bindings, protecting the network against ARP spoofing and man-in-the-middle attacks.

Support for Secure Shell (SSH)

• This update adds SSH access support, allowing administrators to securely manage the switch remotely via encrypted command-line sessions. User can SSH in via the standard port 22.

DHCP Auto Configuration

• This update adds DHCP Auto Configuration, allowing the switch to automatically download and apply its configuration file from a DHCP server during startup. This simplifies large-scale deployments by enabling centralized, zero-touch provisioning of switch settings.

IEEE 802.1X Port-Based Network Access Control

• This update adds 802.1X authentication, enabling port-based access control that requires users to authenticate before gaining network access. Working with a RADIUS server, it ensures only authorized devices can connect to the switch, enhancing network security.

Enhancement

Enhanced ADRA NDR Support

• Enhanced ADRA NDR integration with dedicated VLAN support for improved network detection and response functionality.

UI Enhancement

• Optimized the user interface with navigation style updates for improved clarity and consistency.

Fixed Issues

• Fixed an issue where opening the MC-LAG page could cause continuous loading and subsequent device reboot.
• Resolved intermittent ping loss in MC-LAG environments.
• Fixed an issue where changing the port speed could prevent the port from linking up.
• Fixed an issue where ACL rules could be configured beyond the supported limit of 255.
• Improved MC-LAG stability during prolonged operation.
• Fixed dashboard display issues for breakout port icons and VLAN status layout.
• Fixed an issue where a password change could succeed but the new password could not be used to log in.
