The MAC address from a data stream is not learned if there is no path for that data going out of the switch.įor example, the VLAN may not have been enabled on any of the interfaces other than the one on which data is coming in on. No egress path was set for the incoming data traffic. This causes the MAC address not to be listed in the MAC table.Īfter waiting for 120 seconds, learning is enabled automatically. MAC address is not learned by the switch. A severity 4 syslog message, STM_LEARNING_OVERLOAD, should have been received.Īfter waiting for 120 seconds, learning is enabled automatically. MAC address learning is disabled due to a learning overload (that is, too many new addresses in a short time). A severity 2 syslog message, STM_LEARNING_RE_ENABLE, should be received.

This creates free space for new MAC entries to be learned. A severity 2 syslog message, STM_LIMIT_REACHED, should have been received.Īfter waiting for 180 seconds, the MAC table is flushed and learning is enabled automatically.Īlternatively, wait until some MAC entries are aged out, so that the total learned entries fall below 1500, or enter the clear mac address-table dynamic command to clear out entries. A severity 2 syslog message, STM_LOOP_DETECT, should have been received.Īfter waiting for 180 seconds, learning is enabled automatically. MAC address learning is disabled because of loop detection. MAC Address Table Data traffic is floodingĭata is not getting forwarded, instead it is being flooded to all ports of a VLAN. This chapter includes the following sections:

This chapter describes how to identify and resolve problems that can occur with Layer 2 switching in the Cisco Nexus 5000 Series switch. Layer 2 is the Data Link Layer of the Open Systems Interconnection model (OSI model) of computer networking.

The configuration of the virtual machine can mostly be cloned.

In the case of Windows computers, it is recommended to use sysprep before making the AMI, so that the computer can reset its unique IDs so that it behaves better on the same network as its clones. Any instance then launched from the AMI will have the exact same disk contents. This is the purpose of an Amazon Machine Image (AMI), which can be created from an existing instance.

The contents of the disks can certainly be cloned. The configuration of the virtual machine.When I thinking of what makes a computer, there are two components: The concept of "clone" doesn't quite exist in Amazon EC2.
