vlan
The storage router uses 802.1Q VLAN encapsulation to carry VLAN information on packets sent and
received on the Gigabit Ethernet interface. The 802.1Q packet tag is a four-byte field inserted between
the source MAC address and ether-type fields in the layer 2 header. It consists of a two-byte Tag Protocol
Identifier (TPID) field and a two-byte Tag Control Information (TCI) field. The TPID contains the
“protocol type” field (0x8100), which identifies the packet as a valid 802.1Q tagged packet. The TCI
contains the 12-bit VLAN Identifier (VID) field and a 3-bit User Priority (UP) field.
Use the vlan command to locally configure VLANs when the storage router is connected to a switched
network that does not support VTP but does support 802.1Q VLANs.
VLANs can only be deleted if they are not in use. Use the force keyword to bypass this restriction and
delete a VLAN that is currently in use.
Examples The following set of commands places the storage router in VTP Transparent mode and configures a
VLAN named weblan001 on the storage router. The VID is 45.
[SN5428-2A]# vtp mode transparent
[SN5428-2A]# Jul 30 15:24:02:Vtp:AS_NOTICE :VTP changed to transparent mode
[SN5428-2A]# vlan 45 name weblan001
[SN5428-2A]# Jul 30 15:25:45:Vtp:AS_NOTICE :VLAN 45 added (name=VLAN0045, mtu=1500)
