The LevelOne GTL-2885 TURING is a 28-Port L3 Lite Managed Gigabit Switch built for reliable, high-performance networking in enterprise and industrial environments. It features 24 × Gigabit RJ45 ports and 4 × 1G/10G SFP+ uplink slots, offering flexible copper and fiber connectivity to meet diverse deployment needs.
With advanced Layer 3 Lite functions, the GTL-2885 supports IPv4/IPv6 static routing and an integrated DHCP server for efficient traffic management and optimized network segmentation. Ethernet Ring Protection Switching (ERPS, ITU-T G.8032) ensures fast sub-50 ms failover, delivering superior network resilience and uptime.
Comprehensive security and management tools include RADIUS and TACACS+ authentication, multi-level VLAN support (Port-based, Protocol-based, Private VLAN, Q-in-Q, Tag-based), and flexible control via Web UI, SNMP (v1/v2c/v3), CLI, Telnet, and SSH.
The built-in Device Management System (DMS) streamlines network administration with centralized monitoring, configuration, and diagnostics—providing a scalable and intelligent switching solution for modern business networks.

| Features. |
Ring Management • Supports ITU-T G.8031 Ethernet Linear Protection Switching • Supports ITU-T G.8032 Ethernet Ring Protection Switching L3 Features : • Static Route (IPV4/IPV6) • DHCPv4 Server • DHCPv6 Server Layer 2 Features : Spanning Tree Protocol (STP) • Standard Spanning Tree 802.1d: Spanning Tree Protocol is an OSI layer-2 protocol which ensures a loop free topology for any bridged LAN • Rapid Spanning Tree (RSTP) 802.1w: Rapid Spanning Tree Protocol, which provides for faster spanning tree convergence after a topology change • Multiple Spanning Tree (MSTP) 802.1s: Multiple Spanning Tree Protocol. The MSTP protocol provides for multiple spanning tree instances VLAN • 802.1Q tag-based VLAN: Supports up to 4K VLANs simultaneously (out of 4096 VLAN IDs). • Port-based VLAN: A port member of a VLAN can be isolated to other isolated ports on the same VLAN and Private VLAN. • Private VLAN Edge (PVE): Private VLANs are based on the source port mask, and there are no connections to VLANs. This means that VLAN IDs and Private VLAN IDs can be identical. • Voice VLAN: The Voice VLAN feature enables voice traffic forwarding on the Voice VLAN. • Guest VLAN: The IEEE 802.1X Guest VLAN feature allows a guest VLAN to be configured for each 802.1X port on the device to provide limited services to non-802.1X-compliant clients. • Q-in-Q (double tag) VLAN: Business customers of service providers often have specific requirements for VLAN IDs and the number of VLANs to be supported. • 802.1v Protocol VLAN: Classifying multiple protocols into a single VLAN often imposes VLAN boundaries that are inappropriate for some of the protocols, requiring the presence of a non-standard entity to relay between VLANs the frames bearing the protocols for which the VLAN boundaries are inappropriate. • MAC-based VLAN: The MAC-based VLAN feature allows incoming untagged packets to be assigned to a VLAN and thus classify traffic based on the source MAC address of the packet. • IP Subnet-Based VLAN: In an IP subnet–based VLAN, all the end workstations in an IP subnet are assigned to the same VLAN. In this VLAN, users can move their workstations without reconfiguring their network addresses. • Management VLAN: Management VLAN is used for managing the switch from a remote location by using protocols such as telnet, SSH, SNMP, syslog etc. LACP Trunking • Link Aggregation Control Protocol (LACP) IEEE 802.3ad: Controls whether LACP is enabled on this switch port. LACP will form an aggregation when 2 or more ports are connected to the same partner • Up to 14 groups • Up to 16 ports per group GARP VLAN Registration Protocol (GVRP) • GVRP stands for GARP (Generic Attribute Registration Protocol) VLAN Registration Protocol. It’s a Layer 2 network protocol, for automatic configuration of switches in a VLAN network DHCP Relay • Relay of DHCP traffic to DHCP server in different VLAN • Works with DHCP Option 82 IGMP v1/v2/v3 Snooping • IGMP limits bandwidth-intensive multicast traffic to only the requesters. Supports 1024 multicast groups IGMP Querier • IGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router IGMP Proxy • IGMP snooping with proxy reporting or report suppression actively filters IGMP packets in order to reduce load on the multicast router MLD v1/v2 Snooping • Delivers IPv6 multicast packets only to the required receivers Multicast VLAN Registration (MVR) • It uses a dedicated manually configured VLAN, called the multicast VLAN, to forward multicast traffic over Layer 2 network in conjunction with IGMP snooping |

IEEE 1588v2 PTP • Support IEEE 1588 v2 PTP (Precision Time Protocol). DHCP • DHCP Server: Support DHCP server to assign IP to DHCP clients. • DHCP client: The Dynamic Host Configuration Protocol (DHCP) is a standardized network protocol used on Internet Protocol (IP) networks for dynamically distributing network configuration parameters, such as IP addresses for interfaces and services. Event/Error Log • Support SNMP Trap/Syslog/SMTP. SNMP • SNMP version1, 2c and 3 with support for traps, and SNMP version 3 user-based security model (USM). Remote Monitoring (RMON) • Embedded RMON agent supports RMON groups 1,2,3,9 (history, statistics, alarms, and events) for enhanced traffic management, monitoring and analysis. Firmware Upgrade • Web browser upgrade (HTTP/ HTTPs) and TFTP. • Upgrade through console port as well. Configuration Export/Import • Update of the firmware controlling the switch. Port Mirroring • Traffic on a port can be mirrored to another port for analysis with a network analyzer or RMON probe. Up to N-1 (N is Switch’s Ports) ports can be mirrored to single destination port. A single session is supported. IEEE 802.1ab (LLDP) • Used by network devices for advertising their identities, capabilities, and neighbors on an IEEE 802ab local area network. • Support LLDP-MED (ANSI/TIA-1057) extensions. UPnP • The Universal Plug and Play Forum, an industry group of companies working to enable device-to-device interoperability by promoting Universal Plug and Play. CDP Aware • The CDP operation is restricted to decoding incoming CDP frames (The switch doesn’t transmit CDP frames). CDP frames are only decoded if LLDP on the port is enabled. s-Flow • The industry standard for monitoring high speed switched networks.

BPDU Guard • The BPDU guard, an enhancement to STP, removes a node that reflects BPDUs back in the network.
