FAQ-How the MAC Address of the VLANIF Interface on the NE40 Is Generated

Publication Date:  2012-07-27 Views:  39 Downloads:  0
Issue Description

 Q:
What is the MAC address of the VLANIF interface on the NE40? The MAC address of which interface is used? 

 

Alarm Information
 Null 

 
Handling Process

 A:
1. The VLANIF interface on the NE40 adopts the MAC address of the Ethernet interface on the master SRU. For example:
[R2_NE40]dis int MEth 0
MEth0 current state : UP
Line protocol current state : UP
Description : to-administrator, Route Port
The Maximum Transmit Unit is 1500 bytes
Internet Address is 1.1.1.22/24
IP Sending Frames’ Format is PKTFMT_ETHNT_2, Hardware address is 00e0-fc57-1fe5
[R2_NE40]display int vlanif 100
Vlanif100 current state : DOWN
Line protocol current state : DOWN
Description : Huawei, Quidway Series, Vlanif100 Interface, Route port
The Maximum Transmit Unit is 1500 bytes
Internet protocol processing : disabled
Hardware address is 00e0-fc57-1fe5 ------the same as the MAC address of the Ethernet interface on the master SRU
2. The MAC address of the VLANIF interface is generated as soon as the interface is created, which is irrelevant to whether the VLAN has specific physical interfaces.
3. All the VLANIF interfaces on an NE40 use the same MAC address. For example, the MAC address of VLANIF 200 on the preceding device is also 00e0-fc57-1fe5.
[R2_NE40]display int vlanif 200
Vlanif200 current state : DOWN
Line protocol current state : DOWN
Description : Huawei, Quidway Series, Vlanif200 Interface, Route Port
The Maximum Transmit Unit is 1500 bytes
Internet protocol processing : disabled
Hardware address is 00e0-fc57-1fe5
