If they do, the device considers that the port is on a looped link. Loop detection usually works within a VLAN. If a detection frame is returned with a different VLAN tag than it was sent out with, an inter-VLA
· None—When a loop is detected on a port, the device generates a log but performs no action on the port. · No-learning—When a loop is detected on a port, the device generates a log and disables the port from learning MAC addresses. · Sh...
Each interface can send detection packets with a maximum of 32 VLAN IDs. Views GE interface view, XGE interface view, port group view, Eth-Trunk interface view Default Level 2: Configuration level Usage Guidelines Usage Scenario By default, loopback detection is disabled in VLANs. After theloop...

time —Time interval to send loop-detect frame, in seconds. The range is from 0 to 10. The default is 5. action syslog —Displays a system message and does not error-disable any port. If you use the no form of this command, the system re...
A port from the set of ports can be associated with a port of a multi-chassis aggregate (MCAE) interface and a virtual local area network (VLAN). The processor can generate an untagged data unit and tagged data units. The processor can send the untagged data unit and the tagged data ...
its interfaces connected, then your switch's BPDUs circle back to itself. That's because your switch sends out BPDUs towards the unmanaged switch, and the unmanaged switch sends those BPDUs out all of its other ports, which then send it back via the port that's connected to your ...

Although the figure shows the progress of one such management message M from the GM 202, it will be understood that the GM can send a stream of management messages as part of its normal operations. When a boundary clock receives the management message M on its (ingress) port, the message...
A switch can send a loop-detection frame for a respective interface of the switch or for a respective virtual local area network (VLAN) the switch is configured for. If the switches in a network are configured for different VLANs, they can form VLAN-specific loops. When a switch sends a...
