  • Same IP address repeatedly accesses the switch

    Same IP address repeatedly accesses the switch

    If you have duplicate IP addresses on the network, you can ping that IP address to get an ARP response from one device or the other. You can also look at the local ARP table to see the IP-to-MAC associations for that particular scenario. The issue arises when two or more devices on the same network are assigned the same IP address, creating confusion. Unmanaged switches operate at Layer 2 (Data Link Layer) and forward Ethernet frames based on MAC addresses, not IP addresses. MAC Address Table Learning Unmanaged switches. My connection looks to be intermittently working, sometimes I can't access it, then sometimes I can but I will be disconnected after 1 minute or so. Does anyone have any suggestions on how to approach this issue? Thank you in advance, Ashley 04-04-2013 10:25 AM Check Switch Logs if you have enable. It is assigning the same IP address to multiple devices. None of these are static IP addresses. This is causing all kinds of headaches for me. Depending on the sender, they might receive partial traffic or they might not receive any traffic at all.

  • Configure switch port access delay

    Configure switch port access delay

    To configure the LAG, click on the furthest away switch in the list of devices, then click on 'Ports' Next, click on 'Port Management', which is the new way to manage switch port configurations in UniFi version 7. Port Settings — You can configure the Up or Down state of the port for a specific period. This helps simplify the configuration of the WLC interface ports, increase available bandwidth between the wireless and wired network. Portfast is used to avoid the delay that happens in the spanning tree when connecting a new device to the network. When port fast is enabled on an interface the interface whenever it detects a protocol up the event, the port skips the listening and learning spanning tree states and goes straight to. On the Port settings page, you can configure and monitor individual switch ports, including basic settings, LAG ports with LACP support, advanced features, port mirroring, loopback detection, PoE management with keepalive functionality, and STP configuration for preventing network loops. The basic. When a member port fails, its traffic is automatically switched to other member ports.

  • What are the specific applications of LED fiber optic communication

    What are the specific applications of LED fiber optic communication

    In optical fiber communication systems, LEDs serve as optical sources to convert electrical signals into light pulses. Unlike old-fashioned light bulbs that get hot and burn out, LEDs produce light very coolly and efficiently. The light from the transmitter is coupled into the fiber with a connector and is transmitted through the fiber optic cable plant.
