nwDecIVProtoIfSplitHorizon

Module: CTRON-DECIV-ROUTER-MIB

OID (symbolic): CTRON-DECIV-ROUTER-MIB::nwDecIVProtoIfSplitHorizon

OID (numeric): 1.3.6.1.4.1.52.4.2.2.2.3.3.2.4.1.1.2.1.1.1.11

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This object does not apply to this protocol. It is a common object inherited from the MIB framework used to provide a common management interface to all the Cabletron Routing Services protocol-specific MIBs. Setting this object has no effect.

What is nwDecIVProtoIfSplitHorizon?

nwDecIVProtoIfSplitHorizon is defined by the MIB as a common object inherited from the shared Cabletron Routing Services framework, and the description explicitly states it does not apply to this protocol and that setting it has no effect. An admin should not expect toggling this object to prevent DECnet Phase IV from re-advertising routes back out the interface they were learned on, since the protocol doesn't implement the split-horizon loop-prevention technique the object was defined for. For example, unlike a distance-vector protocol that does support split horizon, setting nwDecIVProtoIfSplitHorizon on this port has no observable effect on DECnet's route advertisement behavior.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.3.2.4.1.1.2.1.1.1.11
snmpwalk -v2c -c public <target> CTRON-DECIV-ROUTER-MIB::nwDecIVProtoIfSplitHorizon

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.3.2.4.1.1.2.1.1.1.11.1
snmpget -v2c -c public <target> CTRON-DECIV-ROUTER-MIB::nwDecIVProtoIfSplitHorizon.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.52.4.2.2.2.3.3.2.4.1.1.2.1.1.1.11.1 i <value>

Start monitoring Cabletron router/multiprotocol switch (legacy DECnet Phase IV) with a free 30-day trial of IPNetwork Monitor. Create custom SNMP monitor using the CTRON-DECIV-ROUTER-MIB::nwDecIVProtoIfSplitHorizon OID value, configure state conditions and alerts, and monitor any Cabletron router/multiprotocol switch (legacy DECnet Phase IV) from a single console.
