ieee8021CnPortPriAlternatePriority

Module: IEEE8021-CN-MIB

OID (symbolic): IEEE8021-CN-MIB::ieee8021CnPortPriAlternatePriority

OID (numeric): 1.3.111.2.802.1.1.18.1.4.1.9

Node type: OBJECT-TYPE

Type: IEEE8021PriorityValue

Access: read-write

Description: The Congestion Notification Priority Value to which an incoming frame is to be mapped, in spite of what the Priority Regereration Table says, if 1) Congestion Notification is enabled and 2) the port is acting in the cptEdge (4) CND defense mode.

This object is ignored unless ieee8021CnPortPriDefModeChoice contains the value cpcAdmin (1).

What is ieee8021CnPortPriAlternatePriority?

The priority an incoming frame gets remapped to on this specific port when congestion notification is enabled and the port is acting in cptEdge defense mode; it only takes effect if ieee8021CnPortPriDefModeChoice is set to cpcAdmin.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.18.1.4.1.9
snmpwalk -v2c -c public <target> IEEE8021-CN-MIB::ieee8021CnPortPriAlternatePriority

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.18.1.4.1.9.1
snmpget -v2c -c public <target> IEEE8021-CN-MIB::ieee8021CnPortPriAlternatePriority.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.111.2.802.1.1.18.1.4.1.9.1 s <value>
