ibSmPortInfoSubnetTimeout

Module: IB-SM-MIB

OID (symbolic): IB-SM-MIB::ibSmPortInfoSubnetTimeout

OID (numeric): 1.3.6.1.3.117.7.1.3.1.1.40

Node type: OBJECT-TYPE

Type: IbTransportTime

Access: read-write

Description: Specifies the maximum expected subnet propagation delay, which depends upon the configuration of the switches, to reach any other port in the subnet and shall also be used to determine the maximum rate which SubnTraps() can be sent from this port. The duration of time is calculated based on (4.096 microsecond * 2 ^ object value)

What is ibSmPortInfoSubnetTimeout?

The maximum expected subnet propagation delay for this port, encoded as 4.096 microseconds times 2 to the value; it also caps how fast SubnTraps can be sent. A value of 18 is about 1 second.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.3.117.7.1.3.1.1.40
snmpwalk -v2c -c public <target> IB-SM-MIB::ibSmPortInfoSubnetTimeout

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.3.117.7.1.3.1.1.40.1
snmpget -v2c -c public <target> IB-SM-MIB::ibSmPortInfoSubnetTimeout.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.3.117.7.1.3.1.1.40.1 s <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ibSmPortInfoSubnetTimeout.1
