zyMulticastUnknownMulticastFrameForwarding

Module: ZYXEL-MULTICAST-MIB

OID (symbolic): ZYXEL-MULTICAST-MIB::zyMulticastUnknownMulticastFrameForwarding

OID (numeric): 1.3.6.1.4.1.890.1.15.3.54.1.1

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Specify the action to perform when the switch receives an unknown multicast frame. Unknown multicast frames are addressed to multicast groups for which the Switch has not recorded any group members. Select Drop to discard the frame(s). Select Flooding to send the frame(s) to all ports of the same domain.

What is zyMulticastUnknownMulticastFrameForwarding?

This object selects whether the switch floods or drops multicast frames addressed to groups it has no recorded members for, choosing between flooding(1) and drop(2). An administrator selects drop on a switch running strict IGMP snooping to prevent unnecessary flooding of unrecognized multicast traffic to every port. For example, setting zyMulticastUnknownMulticastFrameForwarding to drop(2) stops unregistered multicast streams from being blasted out to ports where no host has actually subscribed.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.890.1.15.3.54.1.1
snmpwalk -v2c -c public <target> ZYXEL-MULTICAST-MIB::zyMulticastUnknownMulticastFrameForwarding

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.890.1.15.3.54.1.1.1
snmpget -v2c -c public <target> ZYXEL-MULTICAST-MIB::zyMulticastUnknownMulticastFrameForwarding.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.890.1.15.3.54.1.1.1 i <value>
