acSS7MTP2M3bSlDiscardCongThreshold

Module: AC-SS7-MIB

OID (symbolic): AC-SS7-MIB::acSS7MTP2M3bSlDiscardCongThreshold

OID (numeric): 1.3.6.1.4.1.5003.9.10.12.1.1.1

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-write

Description: This parameter concerns feature that prevents uncontrolled increase of the MTP2 Transmit queue when the upper levels ignores the usual flow control mechanism. Any new SL_TX_MSU_RQ is discarded when the number of msu queued on the TB or RTB overtakes the threshold. Value 0, means that this feature is not activated. Access: Offline. AC INI-Param: SS7M3bSlDiscardCongThreshold

What is acSS7MTP2M3bSlDiscardCongThreshold?

This read-write parameter (0–255) sets a queue-depth threshold above which the SS7 signaling layer discards new requests to prevent uncontrolled memory growth. Operators configure this to protect the system from congestion when upper layers ignore flow control. Setting it to 50, for example, means the queue can hold up to 50 messages before new ones are dropped.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5003.9.10.12.1.1.1
snmpwalk -v2c -c public <target> AC-SS7-MIB::acSS7MTP2M3bSlDiscardCongThreshold

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.5003.9.10.12.1.1.1.1
snmpget -v2c -c public <target> AC-SS7-MIB::acSS7MTP2M3bSlDiscardCongThreshold.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.5003.9.10.12.1.1.1.1 i <value>
