VLAN Commands
A VLAN, or virtual LAN, is a set of nodes that are grouped together into a single
logical network, regardless of their physical location. Multiple VLANs may share
the same physical Ethernet links.
The VMA-series SAN Gateway uses a separate VLAN for low-latency, low-
bandwidth communication between the HP VMA SAN Gateways in a cluster.
Using VLAN commands, interfaces may be configured on a separate VLAN to
allow for the segregation of network and internal cluster traffic.
Network switches must be configured to provide a VLAN for cluster traffic in the
system. Each network switch port connected to a HP VMA SAN Gateway should
be configured to allow VLAN-tagged traffic for the given cluster VLAN ID.
network vlan vlan-id interface
Creates a tagged VLAN interface with as the specified VLAN ID atop
the base interface . Valid VLAN ID values are between 1 and 4094.
A new interface is created, named vlan# where # is . The new
interface can then be configured using the interface commands.
no network vlan vlan-id
Removes the tagged VLAN interface from its base interface.
show vlans [] [configured]
Displays a list of the configured VLANs in the system, or information about a
particular VLAN interface if one is specified by . If configured is
specified, the configured base interface and for the VLAN interface
are shown. Otherwise the current runtime state of the VLAN interface is shown.
