ieee8021STAdminCycleTimeExtension

Module: IEEE8021-ST-MIB

OID (symbolic): IEEE8021-ST-MIB::ieee8021STAdminCycleTimeExtension

OID (numeric): 1.3.111.2.802.1.1.30.1.2.1.1.12

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-write

Description: The administrative value of the CycleTimeExtension parameter for the Port. The value is an unsigned integer number of nanoseconds.

The value of this object MUST be retained across reinitializations of the management system.

What is ieee8021STAdminCycleTimeExtension?

This read-write Unsigned32, in nanoseconds, sets an administrative extension added to the cycle time to absorb rounding, letting an admin fine-tune the schedule boundary when the numerator/denominator fraction doesn't divide evenly.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.30.1.2.1.1.12
snmpwalk -v2c -c public <target> IEEE8021-ST-MIB::ieee8021STAdminCycleTimeExtension

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.30.1.2.1.1.12.1
snmpget -v2c -c public <target> IEEE8021-ST-MIB::ieee8021STAdminCycleTimeExtension.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.111.2.802.1.1.30.1.2.1.1.12.1 i <value>
