cipUrpfDropRateWindow

Module: CISCO-IP-URPF-MIB

OID (symbolic): CISCO-IP-URPF-MIB::cipUrpfDropRateWindow

OID (numeric): 1.3.6.1.4.1.9.9.451.1.1.1

Node type: OBJECT-TYPE

Type: Integer32

Access: read-write

Description: The window of time in the recent past over which the drop count used in the drop rate computation is collected. This global value applies for the computation of all URPF rates, global and per-interface.

Once the period over which computations have been performed exceeds cipUrpfDropRateWindow, every time a computation is performed, the window slides up to end at the current time and start at cipUrpfDropRateWindow seconds before.

The cipUrpfDropRateWindow must be greater than or equal to the interval between computations (cipUrpfComputeInterval).

Since the agent must save the drop count values for each compute interval in order to slide the window, the number of counts saved is the quotient of cipUrpfDropRateWindow divided by cipUrpfComputeInterval.

What is cipUrpfDropRateWindow?

Sets the sliding time window over which dropped-packet counts are collected to compute Unicast Reverse Path Forwarding (URPF) drop rates, applying globally to all interfaces.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.451.1.1.1
snmpwalk -v2c -c public <target> CISCO-IP-URPF-MIB::cipUrpfDropRateWindow

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.451.1.1.1.1
snmpget -v2c -c public <target> CISCO-IP-URPF-MIB::cipUrpfDropRateWindow.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.9.9.451.1.1.1.1 i <value>
