In one embodiment a network device includes multiple interfaces including at least one egress interface, which is configured to transmit packets belonging to multiple flows to a packet data network, control circuitry configured to generate event-reporting data-items, each including flow and event-type information about a packet-related event occurring in the network device, a memory, and aggregation circuitry configured to aggregate data of at least some of the event-reporting data-items into aggregated-event-reporting data-items aggregated according to the flow and event-type information of the at least some event-reporting data-items, store the aggregated-event-reporting data-items in the memory, and forward one aggregated-event-reporting data-item of the aggregated-event-reporting data-items to a collector node, and purge the one aggregated-event-reporting data-item from the memory.

Telemetry event aggregation

A network element connects over a network to a network node via a member link of a Multi-Chassis&#x2014;Link Aggregation Link Group (MC-LAG), and further connects, using inter-peer ports, to peer network elements coupled to the network node via other MC-LAG member links. A processor of the network element is configured to receive from the network first packets destined to the network node, to receive via the inter-peer ports information indicative of second packets received from the network by the peer network elements that are destined to the network node, to select at least some of the first packets for transmission at an egress rate that jointly with egress rates of the peer network elements does not exceed a predefined MC-LAG maximal rate, based on the first packets and the information, and to transmit the selected first packets to the network node at the egress rate.

Rate limiting in a multi-chassis environment by exchanging information between peer network elements

Packet flows received in a data network are assigned to respective entries of a database. During an accumulation interval byte counts of the assigned packet flows are accumulated in the respective database entries. The packet flows are classified as elephant flows when differences between the byte counts and a reference byte count exceed a threshold and are reported after expiration of the accumulation interval.
