Description: HS link FIFO underflows: The number of FIFO underflows on the high-speed links between the ASICs responsible for handling the router interfaces.

What is ifJnxOutHslFifoUnderFlows?

Counts FIFO underflows on the high-speed internal links between the ASICs handling this router's interfaces, meaning an internal buffer ran dry faster than it could be refilled -- an internal forwarding-path issue rather than an external wire problem.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2636.3.3.1.1.30
snmpwalk -v2c -c public <target> JUNIPER-IF-MIB::ifJnxOutHslFifoUnderFlows

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.2636.3.3.1.1.30.1
snmpget -v2c -c public <target> JUNIPER-IF-MIB::ifJnxOutHslFifoUnderFlows.1
