H3C-ARP-RATELIMIT-MIB
AI MIB Summary
The H3C-ARP-RATELIMIT-MIB enables monitoring of ARP packet arrival rates directed to the CPU on H3C network devices to detect potential flooding attacks or CPU saturation events. This module currently exposes metrics for tracking the volume of ARP traffic processed by the control plane, though it does not support real-time rate-limit configuration.
This MIB file defines the ARP packet rate limit configuration. The ARP packet rate limit feature monitors and controls the rate of ARP packets delivered to the CPU on a device. The current version supports the monitoring feature only.

h3cARPRatelimitOverspeedTrapIf the rate of ARP packets delivered to the CPU on a device exceeds the threshold, a trap message is generated and sent to the remote monitoring device. NOTIFICATION-TYPE .1.3.6.1.4.1.2011.10.2.110.1.1.0.1 |

h3cARPRatelimitTrapMsgThis object is the cell section in a trap message sent from a monitored device. This object can contain multiple cells. This object is in the format of '<cell1><cell2>...'. Each cell consists of 17 octets in the format of '<TrapOrigin><IfIndex><OverSpeedValue><Threshold><Interval>'. <TrapOrigin> indicates the source of the trap message and has size of 1 octet. It only supports the following values. 1 - Global. 2 - Interface. <IfIndex> is the index of the interface where the rate of ARP packet exceeds the threshold and has size of 4 octets. It is 0xFFFFFFFF when <TrapOrigin> is 1(Global). <OverSpeedValue> indicates the rate that ARP packets are actually delivered and has size of 4 octets. <Threshold> indicates the threshold that ARP packets can be delivered to CPU and has size of 4 octets. <Interval> indicates the interval that a trap message is sent out and has size of 4 octets.ro OCTET STRING .1.3.6.1.4.1.2011.10.2.110.1.1.1.3 |
