MiRICi-E3T3 Ver. 2.2 4-15
Configuring Loop Detection
MiRICi-E3T3 features a mechanism to detect loops on the LAN side or WAN side
by transmitting special loop detection frames.
³ To configure loop detection:
1. Navigate to Main Menu > Configuration > Applications > Loop detection.
The Loop Detection menu appears.
MiRICi-E3T3
Configuration > Applications > Loop Detection
Loop Detection VLAN [1..4095] 1
LAN Loop Detection Disable
WAN Loop Detection Disable
Table 4-2 Loop Detection Menu
2. From the Loop Detection menu, select the desired parameters as follows:
 Loop Detection VLAN. Choose the VLAN identification number of the loop
detection frame (1..4095).
 LAN Loop Detection. If enabled the loop detection mechanism is activated
for the LAN side
 WAN Loop Detection. If enabled the loop detection mechanism is
activated for the WAN side
Data is normally sent to and from the MiRICi-E3T3 via the LAN/WAN. Once loop
detection is enabled, the unit starts transmitting special loop detection frames.
If the unit recognizes that a loop exists, the following actions are performed
according to the direction/location of the loop:
 If a loop exists on the LAN side the unit sends a loop detection alarm
accordingly.
 If a loop exists on the WAN side the unit stops the traffic to the WAN side
and then sends a loop detection alarm accordingly.
3. Select Save.
