Hi, friend.
The amount of VLAN IDs is 4096: 0-4095. By default, the system automatically allocates 15 reserved VLAN IDs and 2 fixed reserved VLAN IDs of the system from 4079. The range of the reserved VLAN IDs is 4079-4093 and the fixed reserved VLAN IDs of the system are 4094 and 4095. This means that, by default, VLAN IDs later than 4078 are not available. If VLAN IDs larger than 4078 are needed, run the vlan reserve command to modify the reserved VLAN ID (the fixed reserved VLAN ID of the system cannot be modified). Modifying methods are as follows:
Method 1: Assuming that VLAN ID 4093 is required, the 15 VLAN IDs configured to be automatically reserved cannot include 4093. The configuration is as follows:
huawei(config)#vlan reserve
{ start-vlanid<U><2,4079> }:4078
This indicates that the range of the 15 reserved VLAN IDs is 4078-4092. VLAN ID 4093 can be used.
Method 2: If all the large VLAN IDs are required, configure reserved VLAN IDs to start from 2. The configuration is as follows:
huawei(config)#vlan reserve
{ start-vlanid<U><2,4079> }:2
This indicates that the range of the 15 reserved VLAN IDs is 2-16. VLAN ID 17-4093 can be used.
Thanks.
