What Is the MAC Address Range Supported by a VBDIF Interface?

What Is the MAC Address Range Supported by a VBDIF Interface?

When a VBDIF interface is not configured with a MAC address, the MAC address is automatically allocated by the system. You can run the display interface vbdif command to check the MAC address.

You can run the mac-address mac-address command on the VBDIF interface to configure a MAC address for the VBDIF interface. The MAC address ranges on different device models are different.

For CloudEngine 16800:

The switch supports 512 any unicast MAC addresses except the system MAC address and virtual MAC addresses. In addition, the switch supports eight virtual MAC addresses in the range from 0000-5e00-0100 to 0000-5e00-02ff. MAC addresses 0000-5e00-01ff and 0000-5e00-02ff cannot be configured.

For CloudEngine 12800 and 12800E:

  • When the CE12800 works in non-enhanced card interoperability mode, the following situations will occur:
    • If the switch is equipped with the EA series card, CE-L48GT-EC card, or CE-L48GS-EC card, the switch supports eight MAC addresses in the range from 0000-5e00-0100 to 0000-5e00-0107.
    • If the switch is equipped with other cards, it supports eight virtual MAC addresses in the range from 0000-5e00-0100 to 0000-5e00-01ff.
  • The CE12800 in enhanced card interoperability mode supports a maximum of 16 virtual MAC addresses in the range from 0000-5e00-0100 to 0000-5e00-01ff.
  • The CE12800E equipped with ED-E, EG-E, and EGA-E series cards supports 512 any unicast MAC addresses except the system MAC address and virtual MAC addresses. In addition, the switch supports eight virtual MAC addresses in the range from 0000-5e00-0100 to 0000-5e00-02ff.

  • The CE12800E equipped with FD-X series cards supports 1000 any unicast MAC addresses, including virtual MAC addresses in the range from 0000-5e00-0100 to 0000-5e00-02ff.

For CloudEngine 8800, 7800, 6800, 5800:

  • In versions earlier than V200R002C50, MAC addresses supported by the switch are in the range from 0000-5e00-0100 to 0000-5e00-01ff. A maximum of 16 MAC addresses can be configured on the CE6870EI and CE6875EI, and a maximum of 256 MAC addresses can be configured on other switch models.
  • In V200R002C50 and later versions:
    • The CE6870EI and CE6875EI support 16 virtual MAC addresses in the range from 0000-5e00-0100 to 0000-5e00-01ff.
    • The CE5880EI, CE6863, CE6881, and CE6880EI support 512 any unicast MAC addresses except the system MAC address and virtual MAC addresses. In addition, the switch supports eight virtual MAC addresses in the range from 0000-5e00-0100 to 0000-5e00-02ff. Two MAC addresses 0000-5e00-01ff and 0000-5e00-02ff cannot be configured on the CE6881 or CE6863.
    • The CE6865EI support 1000 any unicast MAC addresses, including virtual MAC addresses in the range from 0000-5e00-0100 to 0000-5e00-02ff.
    • Other switch models support 500 any unicast MAC addresses, including virtual MAC addresses in the range from 0000-5e00-0100 to 0000-5e00-02ff.
