atmCESSigABBits
Module: ACE20-MIB
OID (symbolic): ACE20-MIB::atmCESSigABBits
OID (numeric): 1.3.6.1.4.1.164.12.4.3.3.2.1.7
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-write
Description: This attribute is applicable only when value of atmCESSigType is other. Represents the AB bits for Rx/Tx and their masks in this way: bits 7..6: Tx AB bits value, bits 5..4: Tx AB bits mask, bits 3..2: Rx AB bits value, bits 1..0: Rx AB bits mask. All bits must be 0 for CES connection.
What is atmCESSigABBits?
This OID encodes the AB signaling bits for both receive and transmit directions within a single octet, using bits 7–6 for Tx values, 5–4 for Tx mask, 3–2 for Rx values, and 1–0 for Rx mask. Network engineers only configure this for DBCES backup connections; standard CES must have all bits set to zero. A value of 0x00 is correct for regular CES; for DBCES, a value like 0xC0 would set specific signaling bits in the transmit direction.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.164.12.4.3.3.2.1.7 snmpwalk -v2c -c public <target> ACE20-MIB::atmCESSigABBits
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.164.12.4.3.3.2.1.7.1 snmpget -v2c -c public <target> ACE20-MIB::atmCESSigABBits.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.164.12.4.3.3.2.1.7.1 s <value>
