Module: CTRON-DECIV-ROUTER-MIB

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

OID (numeric): 1.3.6.1.4.1.52.4.2.2.2.3.3.2.4.1.1.2.2.1.1.12

Node type: OBJECT-TYPE

Type: Counter

Access: read-only

Description: Indicates the total number of bytes in the DECnet packets that have been discarded, during nwDecIVProtoIfCtrOperationalTime, that were received on the router port for which the entry exists.

What is nwDecIVProtoIfCtrDiscardBytes?

nwDecIVProtoIfCtrDiscardBytes is a read-only Counter tracking the total number of bytes contained in DECnet packets that have been discarded, for the DECnet Phase IV distance-vector-based routing protocol's traffic on this one specific router port, during the relevant OperationalTime measurement window. An admin watching this counter climb faster than expected knows DECnet packets are being dropped somewhere along the forwarding path, warranting investigation into the cause. For example, an unexpected spike in discarded bytes for the routing protocol on this one port would lead an admin to check for congestion or misconfiguration in that port's routing-protocol traffic.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.3.2.4.1.1.2.2.1.1.12
snmpwalk -v2c -c public <target> CTRON-DECIV-ROUTER-MIB::nwDecIVProtoIfCtrDiscardBytes

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.3.2.4.1.1.2.2.1.1.12.1
snmpget -v2c -c public <target> CTRON-DECIV-ROUTER-MIB::nwDecIVProtoIfCtrDiscardBytes.1
