Description: The atm tca sp pearl overflow CBR threshold.

What is cardATMTcaSPPearlOCbrThresh?

This sets the CBR queue depth on the switching port's Pearl ASIC at which the card declares a threshold-crossing overflow alert. Tuning this threshold specifically for the CBR queue on the Pearl switching ASIC lets an admin set a tighter tolerance for this latency-critical traffic class than they might use for the VBR or ABR overflow thresholds elsewhere on the same card. For example, an admin sets a lower overflow threshold for CBR than for ABR queues on the same port, reflecting that even small CBR queue buildups threaten voice quality more than similar buildups in best-effort traffic.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.7.2.1.150
snmpwalk -v2c -c public <target> CASCADE-MIB::cardATMTcaSPPearlOCbrThresh

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.7.2.1.150.1
snmpget -v2c -c public <target> CASCADE-MIB::cardATMTcaSPPearlOCbrThresh.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.277.1.7.2.1.150.1 i <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> cardATMTcaSPPearlOCbrThresh.1
