ds1DataTransferType

Module: ACMIB

OID (symbolic): ACMIB::ds1DataTransferType

OID (numeric): 1.3.6.1.4.1.1751.2.18.2.5.1.11

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: DS1 data transfer type is only applicable in Circuit Emulation where unstructured CE packets entire T1 frame including the F-bit into the AAL1 for data tranfer, whereas, the structured CE packets the entire T1 frame except the F-bit.

What is ds1DataTransferType?

This OID selects whether circuit emulation over ATM carries the entire T1 frame (unstructured) or omits the framing bit F (structured), controlling how much bandwidth the T1 actually consumes over the ATM link. Network engineers choose based on whether the end application needs to recover the original T1 frame structure or just the user data. For instance, unstructured mode includes the F-bit and all overhead, requiring more ATM bandwidth (8 extra bits per frame), while structured omits it and is more efficient for pure data.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.2.5.1.11
snmpwalk -v2c -c public <target> ACMIB::ds1DataTransferType

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.2.5.1.11.1
snmpget -v2c -c public <target> ACMIB::ds1DataTransferType.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1751.2.18.2.5.1.11.1 i <value>
