Mac-Vlan Trigger Enable - H3C S7500E Series Command Reference Manual

of this type describes the relationship between a group of MAC addresses and a VLAN, and a priority
value. Another table contains the MAC address-to-VLAN entries configured without the mask keyword
specified. A MAC address-to-VLAN entry of this type describes the relationship between a single MAC
address and a VLAN, and a priority value. The system adds/removes MAC address-to-VLAN entries
to/from the two tables according to your configuration.
Examples
# Associate a single MAC address 0-1-1 with VLAN 100 and 802.1p priority 7.
<Sysname> system-view
[Sysname] mac-vlan mac-address 0-1-1 vlan 100 priority 7
# Associate the MAC addresses with the high-order six hexadecimal digits being 111122 with VLAN
100 and 802.1p priority 4.
<Sysname> system-view
[Sysname] mac-vlan mac-address 1111-2222-3333 mask ffff-ff00-0000 vlan 100 priority 4

Parameters
None
Description
Use the mac-vlan trigger enable command to enable MAC-based dynamic port assignment, that is,
enable the current port to be dynamically assigned to VLANs based on the source MAC addresses of
the received packets.
Use the undo mac-vlan trigger enable command to restore the default.
By default, MAC-based dynamic port assignment is not enabled.
After receiving a packet with an unknown source MAC address, a port submits the packet to the CPU.
If the source MAC address matches a MAC address-to-VLAN mapping (whose mask is all Fs)
maintained by the device, the device dynamically learns the source MAC address and assigns the
receiving port to the corresponding VLAN. Then, subsequent packets with this source MAC address
can be directly forwarded through the port. If the MAC address does not match any MAC
address-to-VLAN mapping or matches only a MAC address-to-VLAN mapping whose mask is not all
Fs, the device will not dynamically learn the MAC address and assign the receiving port to the
corresponding VLAN.
Examples
# Enable MAC-based dynamic port assignment on GigabitEthernet 2/0/1.
