◇ Low power consumption, no fan, aluminum shell. ◇ ALC, filter data packet through configuring matching rules, processing operation & time permission, and provide flexible and safe access control. ◇ QoS, Priority mode based on 802.1P, Port & DSCP, queue scheduling algorithm including EQU, SP, WRR & SP+WRR. ◇ IEEE802.1Q VLAN, flexible VLAN division, Voice VLAN, and QinQ configuration. ◇ Support full-duplex based on IEEE802.3x and half-duplex based on b ackpressure. ◇ Support non-blocking wire-speed forwarding.
MAC ETHERNET SWITCH FULL
◇ Support line-speed full Gigabit Ethernet port, which facilitates flexible networking of users and meets networking requirements in various scenarios. It is suitable for intelligent transportation, rail transit, power industry, mining, petroleum, shipping, metallurgy, and green energy construction and other industrial scenarios to form a cost-effective, stable, and reliable network.įull Gigabit access, wire-speed transmission Industrial switches meet the needs of the industrial Ethernet application environment. According to the actual application requirements, you can configure multiple application services such as port traffic control, VLAN division, and SNMP through the Web network management mode. When the one-way network fails, communication can be quickly restored to ensure important Uninterrupted communication for applications. Support multiple network redundancy protocols STP/RSTP/MSTP (<50ms) and (ITU-T G.8032) ERPS(<20ms) to improve link backup and network reliability. The ONV-IPS33016M has L2+ network management function, support IPV4/IPV6 management, static route full line-rate forwarding, security protection mechanism, ACL/QoS policy and rich VLAN functions, and is easy to manage and maintain. Each port can support wire-speed forwarding.

MAC ETHERNET SWITCH PC
Thus switch learns PC MAC address even before the data traffic flow or PING process.The ONV-IPS33016M is a full gigabit L2+ managed industrial E thernet switch independently developed by ONV. The destination IP address must be a PC2 IP address but here it has PC1 IP address, so it will drop the packet. At layer 3, it will check the destination IP address. Since it’s broadcast MAC address, it will accept and send to Layer 3. PC2 also receives the packet, and it will check the destination MAC address first. MAC Address Table Switch#show mac-address-table Now, if you run the command in Switch, you will see PC1 MAC-address entry in MAC address table.
MAC ETHERNET SWITCH UPDATE
The switch receives the packet, and it will learn the MAC address of the PC1, and it will update in the MAC address table. Since it’s a broadcast frame, it will be flooded to the network. It immediately generates an ARP packet with broadcast destination mac address and destination IP address with its own IP address 192.168.0.1.Īlso note that, in this packet, you can see the PC1 source MAC address and source IP address. MAC Address table Switch#show mac-address-table So there is no chance of learning PC MAC address by a switch.Īt this point, when we run the command in switch, then you will see no entry in the MAC address table. So it will drop the frames and never send back a reply switch. Īs you know, PC is a layer 3 device, and it has no service to accept Layer 2 protocol frames. These frames have a multi-cast destination MAC address, so these frames will be flooded to both PCs. Usually, the switch sends Layer 2 protocol frames like STP(Spanning-tree protocol), CDP(Cisco Discovery Protocol), and DTP(Dynamic Trunking Protocol)in periodic time intervals. Both PCs have MAC addresses and the switch maintains the MAC address table, and it will learn all MAC addresses in the network. There is a switch in the middle and 2 PCs are connected to switch Ethernet ports. Note: There are no assigned IP Addresses to PCs. Let’s take an example of 2 PC’S connected to Switch.
