Description: Maximum receive/transmit buffer size for the ATM UNI DS3 IOP

What is pportMaxBufferSize?

This sets the maximum receive/transmit buffer size configured for the ATM UNI DS3 I/O processor on this port. A larger buffer here lets this specific port absorb bigger traffic bursts before discarding cells, at the cost of added queuing latency, so it is a direct knob for trading off burst tolerance against delay on this DS3 circuit. Undersizing this buffer relative to the traffic mix on a heavily bursty DS3 uplink would show up as rising pportOutDiscardsCell on this same port during peak periods.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.4.2.1.34
snmpwalk -v2c -c public <target> CASCADE-MIB::pportMaxBufferSize

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.4.2.1.34.1
snmpget -v2c -c public <target> CASCADE-MIB::pportMaxBufferSize.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.277.1.4.2.1.34.1 i <value>
