Command Modes Administrator.
Command History
Usage Guidelines In a cluster environment, VLAN management functions are handled by a single storage router. To
determine which storage router is performing VLAN management functions, issue the show cluster
command. If you issue the vlan command from a storage router that is not performing VLAN
management functions, the CLI displays an informational message with the name of the node that is
currently handling those functions. See Chapter 11, “Maintaining and Managing the SN 5428-2 Storage
Router,” for more information about operating the storage router in a cluster.
VLANs are a cluster-wide configuration item. When configured and saved to the bootable configuration,
HA communications will propagate the VLAN information to all storage routers in the cluster. You can
configure a maximum of 16 logical interfaces (VLANs associated with IP addresses) per physical
Gigabit Ethernet interface in the SN 5428-2 or cluster.
VLAN information can only be configured when the storage router is in VTP Transparent mode. In
transparent mode, received VTP packets are ignored and VLAN configuration information is retrieved
from the high availability cluster.
vid VLAN identification (VID) number. Enter an integer from 1 to 4095.
name vlan_name (Optional) The name of the VLAN, which can be up to 32 characters in
length. If not specified, the default VLAN name has VLAN as the prefix
followed by the VID, left padded to four bytes (for example, VLAN0002,
or VLAN0045).
mtusize nn The size of the maximum transfer unit, in bytes. nn is an integer from 1500
to 9000. The default MTU is 1500.
force (Optional) Keyword that overrides normal protections, allowing the action
to be performed.
