# Configure port GigabitEthernet 3/0/2 as a trunk port, and assign it to all VLANs. Create service
instance 1 on port GigabitEthernet 3/0/2, configure the port-based match criteria, and associate
the service instance with MAC-in-MAC instance aaa by using the access mode of Ethernet.

2. Configure Device B:
Configure Device B as you configure Device A. (Details not shown.)
Verifying the configuration
Use the display minm connection command to display the uplink connection information (that is, the
remote B-MAC information learned) of MAC-in-MAC instance aaa. For example:
# Display the uplink connection information of MAC-in-MAC instance aaa on Device A.
[DeviceA] display minm connection vsi aaa

Troubleshooting
Symptom
The customer frames cannot be transmitted to the peer network by using MAC-in-MAC.
Analysis
The possible reasons are:
• No VSI of the MAC-in-MAC type is configured on the BEB, or the configured VSI is down.
• The MAC-in-MAC configurations on the BEBs are inconsistent.
• The B-VLAN in the BEB is not created on the BCB, or the ports connecting the BEB and BCB are not
both assigned to the B-VLAN.
Solution
To resolve the problem:
1. User the display vsi verbose command to display the MAC-in-MAC configuration of the VSI. If the
VSI is not configured with MAC-in-MAC, configure it. If the VSI is down, use the undo shutdown
command to bring the VSI up. For more information about the display vsi verbose command, see
MPLS Command Reference.
2. Use the display vsi verbose command on all BEBs to see whether they are consistent in the
MAC-in-MAC configuration, especially the I-SID and B-VLAN. The MAC-in-MAC configurations on
the BEBs should be consistent.
