小笔记：VLAN 范围 1-4096 （ vlan 0 和 VLAN 4095 用途 ）

 

 

 

VLAN 4095

 

 

The reserved value 0x000 indicates that the frame does not carry a VLAN ID; in this case, the 802.1Q tag specifies only a priority (in PCP and DEI fields) and is referred to as a priority tag. 

 

vlan 4095. In Nortel switches, VLAN 4095 is used by the CPU internally to desiginate an invalid VLAN.
