Table 258: Loop Protection Configuration Fields
Field
Description
Loop Protection
Enables or disables the loop protection feature globally on the switch.
The loop protection feature is not supported on dynamic trunks. The loop protection
feature will be automatically disabled if it was previously enabled on a static trunk that
is now configured as dynamic.
Transmission Time
(Seconds)
The interval at which the switch sends loop protection PDUs on interfaces that are
enabled to send them.
Maximum PDU
Received
The count of loop protection packets received by the switch after which the interface
will be err-disabled.
Interface
The port or trunk ID.
Select an interface to and click
Edit
to edit the Loop Protection port configuration. Click
Edit All
to apply the same configuration to all interfaces.
Action
The action to be taken when a loop is detected on the port:
•
Shutdown Port: Shut down the port for the configured Transmission Time.
•
Shutdown Port and Log: Shut down the port for the configured Transmission Time
and send a message to the system log.
•
Log Only: Send a message to the system log but do not shut down the port.
Status
The current status of the interface. Link Up indicates the interface is operating normally.
Link Down indicates that the port has been shut down due to the detection of a loop.
Loop
Whether a loop is currently detected on the interface. If blank, then no loop is detected.
Loop Count
The number of times a loop has occurred on the interface.
Time of Last Loop
The date and time the most recent loop was detected.
Click
Submit
to updated the switch. The changes take effect but will not be retained across a power
cycle unless a save is performed.
Multiple Registration Protocol Configuration
Like 802.1AS, Multiple Registration Protocol (MRP) is an Audio Video Bridging (AVB) feature that is
available on some 200 Series platforms. MVR is a base registration protocol that enables devices
running an MRP application to register attributes to other devices in a network. MRP provides an
application to register attributes such as bandwidth requirement for a given AV stream and MAC
address information. It is used by various applications to propagate the registration. 200 Series switches
support the following MRP applications:
•
Multiple MAC Registration Protocol (MMRP)
•
Multiple Stream Reservation Protocol (MSRP)
•
Multiple VLAN Registration Protocol (MVRP)
MMRP allows for the propagation MAC address information in the network, and allows for the
registration and deregistration of both individual MAC address information and group MAC address
membership. End stations may request to join or leave a multicast group, or to register an individual
MAC address with a specific VLAN. MAC address entries can be dynamically registered and
deregistered if MMRP is administratively enabled on the switch.
