Module: ETH-SWITCH-MIB
OID (symbolic): ETH-SWITCH-MIB::rxNiaOverRunDrops
OID (numeric): 1.3.6.1.4.1.208.39.4.2.1.53
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: The NIA RX buffer gets in overrun if the nimbus is overloaded. This should only happen if a configuration is made which loads the Nimbus with more than a load equal to 44 simplex 10Mbit net.
What is rxNiaOverRunDrops?
Counts receive-buffer overrun events on this port's NIA network-interface-adapter chip, occurring when the switch's internal fabric (the 'Nimbus') is overloaded past roughly the equivalent of 44 simplex 10 Mbit connections. A nonzero value indicates the switch's backplane, not just this one port, is oversubscribed.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.208.39.4.2.1.53 snmpwalk -v2c -c public <target> ETH-SWITCH-MIB::rxNiaOverRunDrops
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.208.39.4.2.1.53.1 snmpget -v2c -c public <target> ETH-SWITCH-MIB::rxNiaOverRunDrops.1
