MFLP/4/hwMflpIfBlock_active

Message

MFLP/4/hwMflpIfBlock_active: The interface turned to block state. (VLAN ID=[vlanid], Interface Name=[acifname], Block Time=[blocktime], Block Reason=[blockreason], DetectMAC=[mac])

Description

An interface is blocked.

Parameters

Parameter Name	Parameter Meaning
vlanid	VLAN ID
acifname	Interface name
blocktime	Blocking time
blockreason	Reason for the blocking
mac	Detected MAC address

Possible Causes

Cause 1: The interface has been blocked for VLAN loop, and the port has already been permanently blocked.
Cause 2: The interface has been blocked for VLAN loop, and the loop has already been punished times times.

Procedure

Cause 1: The interface has been blocked for VLAN loop, and the port has already been permanently blocked.
1. Run the display current-configuration command to check whether the loopback local command is configured on interfaces corresponding to the VLAN.
- If the loopback local command is configured on interfaces corresponding to the VLAN, delete the command configuration and check whether the alarm is cleared. If the alarm persists, go to Step 2.
- If the loopback local command is not configured on interfaces corresponding to the VLAN, go to Step 2.
2. Log in to the device and run the reset loop-detect eth-loop vlan vlan-id { all | interface interfacetype interfacenumber } command to unblock the interfaces and check whether hwMflpIfBlock_clear is reported. If hwMflpVlanAcResume is not reported, go to Step 3.

3. Collect alarm information and configuration information, and then contact technical support personnel.
Cause 2: The interface has been blocked for VLAN loop, and the loop has already been punished times times.
1. Run the display current-configuration command to check whether the loopback local command is configured on interfaces corresponding to the VLAN.
- If the loopback local command is configured on interfaces corresponding to the VLAN, delete the command configuration and check whether the alarm is cleared. If the alarm persists, go to Step 2.
- If the loopback local command is not configured on interfaces corresponding to the VLAN, go to Step 2.
2. Check whether the interface recovers after the block-time specified in the loop-detect eth-loop command expires. If the interface does not recover, go to Step 3.

3. Collect alarm information and configuration information, and then contact technical support personnel.
