4.3.6Tagged VLAN

The 2GXM supports the IEEE 802.1Q tag VLAN packet tagging and un-tagging and the 802.1p Quality of Service priority standards.

The following parameters are configured for each port:

4.3.6.1Port Priority (PRI)

This (IEEE 802.1p based) user-specified value of 0 through 7 can be assigned as a QoS priority level (0 being lowest and 7 being highest) to packets ingressing (entering) a port. If no value is specified by the user, a default priority value of “0” is assigned.

The PRI value is always assigned to all untagged packets. Tagged packets are assigned the PRI value when the “PVID” option is selected in the “Tagged Packet Use” section.

4.3.6.2Port VLAN ID (PVID)

This (IEEE 802.1Q based) user-specified value of 0 through 4094 can be assigned as a Port VLAN ID (PVID) to packets ingressing a port. If no value is specified by the user a default PVID value of “2” is assigned.

The PVID value is always assigned to untagged packets. Tagged packets are assigned the PVID value when the “PVID” option is selected in the “Tagged Packet Use” section.

4.3.6.3Tagged Packet Use

This section defines how tagged packets ingressing a port are processed.

Selecting the “PVID” option causes the PRI and PVID user-specified values to be used as the packet’s VLAN ID (VID) for processing of the packet.

Selecting the “TVID” (Tagged VLAN ID) option causes the packet’s original Tag VLAN ID (TVID) and priority level to be used as the packet’s VLAN ID (VID) for processing of the packet.

NOTE:Untagged packets are always assigned the port’s PRI and PVID values as their VID.

4.3.6.4Ingress Security

This is a global setting for the module.

Selecting the “Low” option allows any packet to ingress a port.

Selecting the “High” option allows only packets that are assigned a VLAN ID (VID) value of which this port is a member (according to the Membership Table) to ingress a port.

4.3.6.5Egress Policy

Selecting the “untag” option defines how a tagged or untagged packet is processed. A tagged packet will have the top tag removed and an untagged packet will be passed unmodified.

Selecting the “tag” option will tag an untagged packet with the PVID and PRI of the ingress port.

A tagged packet will egress without change if PVID is selected or substituted to tag if TVID is selected.

2GXM specifications

Omnitron Systems Technology has made significant strides in the realm of networking solutions, particularly with its innovative 2GXM series of managed Ethernet switches. These devices are designed to cater to the growing demands for reliable, high-speed network connectivity in industrial environments. The 2GXM series stands out with its robust features, advanced technologies, and versatile characteristics that meet the needs of various applications ranging from industrial automation to surveillance systems.

One of the main features of the Omnitron 2GXM is its support for Gigabit Ethernet with both copper and fiber interfaces. This dual capability allows for flexible network configurations, enabling users to extend their network range while maintaining high data transmission speeds. The switch supports a variety of port combinations, including SFP slots for fiber connections and standard Ethernet ports, facilitating seamless integration into existing infrastructures.

In addition to its connectivity options, the 2GXM series includes advanced management functionalities. It supports SNMP (Simple Network Management Protocol), allowing network administrators to monitor device performance, configure settings, and manage the network from a centralized platform. The switch also features VLAN support, providing enhanced network segmentation and security by allowing the separation of different network traffic types.

Another critical aspect of the 2GXM series is its rugged design, making it an ideal choice for industrial environments. It is built to withstand harsh conditions, including extreme temperatures, vibrations, and electromagnetic interference. This durability ensures maximum uptime and reliability, which are essential for mission-critical applications.

The 2GXM also features Power over Ethernet (PoE) capabilities, enabling it to supply power to connected devices such as IP cameras and wireless access points. This not only simplifies installation but also reduces the need for additional power sourcing, enhancing overall efficiency.

Furthermore, the switch incorporates advanced security features, including port security and access control lists (ACLs), to safeguard the network against unauthorized access and potential threats. This focus on security reassures users that their industrial operations can run smoothly and safely.

In summary, the Omnitron Systems Technology 2GXM series of managed Ethernet switches offers a compelling combination of high-speed connectivity, advanced management features, rugged construction, and enhanced security. These characteristics make it a preferred choice for enterprises looking to strengthen their industrial networks while achieving operational efficiency and reliability.
