Forwarded to empty port 3, the empty corresponding ports 3 of port 3 and vlan 100.
Port 2, vlan 2 is mapped to empty port 2, then carries out vpls mac study, and interchanger is accordingly searched, looked for
Forwarded to empty port 3, the empty corresponding ports 3 of port 3 and vlan 100.
If up not finding purpose mac, then isolation is flooded between empty port 1,2, will not forward, still can go to
Empty port 3.It can be seen that flooding isolation can avoid unnecessary flow from forwarding.
When transmitting downlink data,
Vlan100+port3 is mapped to empty port 3, then carries out vpls mac study, and switch system is accordingly looked into
Look for, a fixed empty port 1 or 2 can only be gone to by now searching, then vlan, all be complete one because purpose mac addresses
Sample, now acl rule meeting matching message determines the purpose void port of message according to the source mac addresses of data message.If
Rule 1 is matched, i.e. source mac is 101, then just go to empty port 1, message is sent to port 1, and vlan is revised as 1, if matching
Upper regular 2, then just it is sent to empty port 2, message is sent to port 2, and vlan is revised as 2. it is achieved thereby that same mac addresses,
