open systems management style
The mode that is used for open fabrics. See also
open-systems mode
The management mode used to specify director or switch port connectivity when the product is
attached to other HP products or OSI-compliant devices as part of an open fabric.
Open Trunking
Open Trunking is a licensed optional feature that enables load balancing of traffic flows. Open
Trunking monitors the average speed of data traffic through a flow. In the event of traffic
congestion, or if traffic on an ISL is disproportionate, a traffic flow is rerouted to a less
congested ISL. See also
operating state (director)
The operating states are described as follows:
Online - when the director is set online, an attached device can log in to the director if the
port is not blocked. Attached devices can communicate with each other if they are
configured in the same zone.
Offline - when the director is set offline, all ports are set offline. The director transmits the
offline sequence (OLS) to attached devices, and the devices cannot log in to the director.
operating state (port)
Valid states are:
Online, offline, or testing.
Beaconing.
Invalid attachment.
Link incident or link reset.
No light, not operational, or port failure.
