ProSAFE 8-Port or 16-Port Gigabit Smart Managed Switch Model GS418TPP, GS510TLP, and GS510TPP 6. From the Interface menu, select the interface. 7. In the Static MAC Address field, enter the MAC address. 8. From the VLAN ID menu, select the VLAN ID that must be associated with the MAC address. 9. Click the Add button. The static MAC address is added to the switch. Configure Layer 2 Loop Protection Loops inside a network are costly because they consume resources and reduce the performance of the network. Detecting loops manually can be cumbersome. The switch can automatically identify loops in the network. You can enable loop protection per port or globally. If loop protection is enabled, the switch sends predefined PDU packets to a Layer 2 multicast destination address (09:00:09:09:13:A6) on all ports for which the feature is enabled. You can selectively disable PDU packet transmission for loop protection on specific ports even while port loop protection is enabled. If the switch receives a packet with the previously mentioned multicast destination address, the source MAC address in the packet is compared with the MAC address of the switch. If the MAC address does not match, the packet is forwarded to all ports that are members of the same VLAN, just like any other multicast packet. The packet is not forwarded to the port from which it was received. If the source MAC address matches the MAC address of the switch, the switch can perform one of the following actions, depending on how you configure the action: • The port is shut down. • A log message is generated. (If a syslog server is configured, the log message can be sent to the syslog server.) • The port is shut down and a log message is generated. If loop protection is disabled, the multicast packet is silently dropped. Loop protection is not intended for ports that serve as uplinks between spanning tree-aware switches. It is intended for unmanaged switches that drop spanning tree BPDUs. Loop protection detects physical and logical loops between Ethernet ports on a device. You must enable loop protection globally before you can enable and configure it at the interface level. Loop protection is supported on physical interfaces and static LAG interfaces, but not on dynamic LAG interfaces. Configure Switching 207

From the

Interface

menu, select the interface.

In the

Static MAC Address

field, enter the MAC address.

From the

menu, select the VLAN ID that must be associated with the MAC

address.

Click the

Loops inside a network are costly because they consume resources and reduce the

performance of the network. Detecting loops manually can be cumbersome.

The switch can automatically identify loops in the network. You can enable loop protection

per port or globally.

If loop protection is enabled, the switch sends predefined PDU packets to a Layer 2 multicast

destination address (09:00:09:09:13:A6) on all ports for which the feature is enabled. You can

selectively disable PDU packet transmission for loop protection on specific ports even while

port loop protection is enabled. If the switch receives a packet with the previously mentioned

multicast destination address, the source MAC address in the packet is compared with the

MAC address of the switch. If the MAC address does not match, the packet is forwarded to

all ports that are members of the same VLAN, just like any other multicast packet. The packet

is not forwarded to the port from which it was received.

If the source MAC address matches the MAC address of the switch, the switch can perform

one of the following actions, depending on how you configure the action:

•

The port is shut down.

•

A log message is generated. (If a syslog server is configured, the log message can be

sent to the syslog server.)

•

If loop protection is disabled, the multicast packet is silently dropped.

Loop protection is not intended for ports that serve as uplinks between spanning tree–aware

switches. It is intended for unmanaged switches that drop spanning tree BPDUs. Loop

protection detects physical and logical loops between Ethernet ports on a device. You must

enable loop protection globally before you can enable and configure it at the interface level.

Loop protection is supported on physical interfaces and static LAG interfaces, but not on
