Which HPE Virtual Connect feature allows an administrator to suppress excessive inbound multicast broadcast and destination lookup failure (OLF)…

Storm control is the specific HPE Virtual Connect feature designed to prevent network degradation caused by excessive traffic. It monitors the levels of inbound broadcast, multicast, and Destination Lookup Failure (DLF) packets on a port. When the traffic rate for these packet types exceeds a pre-configured threshold, the storm control feature suppresses the excess packets, thereby protecting the network from being overwhelmed. This directly matches the function described in the question.

A. Pause flood protection: This feature is related to Ethernet flow control (IEEE 802.3x) and prevents a port from being disabled by an excessive number of incoming pause frames, not data traffic storms.

B. Loop protection: This feature detects and mitigates network topology loops, which are a common cause of broadcast storms. However, storm control is the mechanism that directly limits the rate of the storm traffic itself.

C. LLDP tagging: Link Layer Discovery Protocol (LLDP) is used by network devices to advertise their identity and capabilities to neighbors on a LAN. It is a discovery protocol, not a traffic control mechanism.

Section: "Storm control"

Quote: "Storm control enables you to control the rate of broadcast

multicast

and destination lookup failure (DLF) traffic that is sent to an uplink port. When the amount of specified traffic sent to a port exceeds the configured limit

you can configure the port to drop the excess traffic or shut down."

Reference: Section: "Edit a logical interconnect"

Subsection: "Storm control"

Quote: "Enable or disable storm control on the uplink ports. Storm control prevents traffic on a LAN from being disrupted by a broadcast

multicast

or unicast storm on a port." This confirms the feature's purpose in the Synergy environment

which uses Virtual Connect technology.
