vctVcfrCombErrorsFromSubnet

Module: Nortel-Magellan-Passport-VcTesterMIB

OID (symbolic): Nortel-Magellan-Passport-VcTesterMIB::vctVcfrCombErrorsFromSubnet

OID (numeric): 1.3.6.1.4.1.562.2.4.1.5130.5.12.1.6

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-only

Description: This attribute records the number of subnet packets discarded at the sink Vc due to the Vc segmentation and combination protocol error. Usually, this occurs when the subnet discards packets and thus this statistics can be used to guest the number of subnet packets that are not delivered to the Vc. It cannot be used as an actual measure because some subnet packets may have been delivered to Vc but have to be discarded because these are partial packets to a frame in which some other partial packets have not been properly delivered to Vc

What is vctVcfrCombErrorsFromSubnet?

Counts subnet packets discarded at the sink Vc due to a segmentation/combination protocol error. The MIB cautions this figure can only be used to guess (not precisely measure) how many subnet packets never reached the Vc, since some legitimately-delivered partial packets are still discarded here when a sibling partial packet of the same frame was lost.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.562.2.4.1.5130.5.12.1.6
snmpwalk -v2c -c public <target> Nortel-Magellan-Passport-VcTesterMIB::vctVcfrCombErrorsFromSubnet

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.562.2.4.1.5130.5.12.1.6.1
