The Loop-IP6800 has two WAN optical interfaces, two RS232/485 DTE interfaces, three Ethernet LAN interfaces, two sets of dry contact IN/OUT interfaces, and one alarm relay connector.
Ethernet RJ45 Loopbacks: These are used to test the ports on copper-based Ethernet network interface cards (NICs), switches, and routers. How to
By creating a local loop, technicians can determine whether network slowdowns are due to hardware issues or external factors. Router and Switch
You can test/check for network loops without disabling any ports by using Loop-Protect and setting the Receiver-Action to "no-disable". This will allow the switch to check for a loop.
Te5/1 Desg BLK 2 128.513 P2p self-looped Cisco Switch sees its own BPDU back, so it shows as a loop, only 2 VLANs show looped? rest all ok, then i will look where these VLANs are
