pportBipErrorsThresh
Module: CASCADE-MIB
OID (symbolic): CASCADE-MIB::pportBipErrorsThresh
OID (numeric): 1.3.6.1.4.1.277.1.4.2.1.79
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The threshold of BIP errors. If the number of line BIP-24/8 rrors persists to exceed this value, the pport will be taken down and a trap will be issued: 1-port ATM-IWU STM-1/STS-3c card: -------------------------------- 1 - ignore BIP errors 4 - 10^-4 errors 5 - 10^-5 errors 6 - 10^-6 errors
What is pportBipErrorsThresh?
This sets the BIP error-rate threshold, expressed as an exponent like 10^-4, 10^-5, or 10^-6, or 1 to ignore BIP errors entirely, above which this port will be automatically taken down and a trap issued, per the 1-port ATM-IWU STM-1/STS-3c card's value table. Because exceeding this threshold actually takes the port down rather than just alerting, this setting on this specific port is a protective mechanism against running a link with a degraded bit-error rate that would otherwise silently corrupt traffic, at the cost of that port becoming unavailable during a marginal-but-not-total failure. Setting this to 5 (10^-5) on this port means a sustained BIP error rate worse than 1 in 100,000 bits will pull the port down automatically rather than let it continue passing increasingly corrupted traffic.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.4.2.1.79 snmpwalk -v2c -c public <target> CASCADE-MIB::pportBipErrorsThresh
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.4.2.1.79.1 snmpget -v2c -c public <target> CASCADE-MIB::pportBipErrorsThresh.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.277.1.4.2.1.79.1 i <value>
