ibSmSwitchInfoDefPriMcastPort

Module: IB-SM-MIB

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

OID (numeric): 1.3.6.1.3.117.7.1.4.1.1.8

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-write

Description: Forward to this port all the multicast packets from the other ports whose DLID does not exist in the forwarding table.

What is ibSmSwitchInfoDefPriMcastPort?

The port to which the switch forwards multicast packets from other ports whose destination LID is missing from the forwarding table (writeable, 0-255). It is the default primary multicast egress, so set it deliberately on switches that carry multicast.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.3.117.7.1.4.1.1.8
snmpwalk -v2c -c public <target> IB-SM-MIB::ibSmSwitchInfoDefPriMcastPort

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.3.117.7.1.4.1.1.8.1
snmpget -v2c -c public <target> IB-SM-MIB::ibSmSwitchInfoDefPriMcastPort.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.3.117.7.1.4.1.1.8.1 i <value>
