Module: ADN-ENV-MIB

OID (symbolic): ADN-ENV-MIB::adnAeiPortDefSignalling

OID (numeric): 1.3.6.1.4.1.637.3.1.8.5.5.21.1.9

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This indicates the defect signalling in addition to the report towards the control unit (CU). It is coded as a bit map. The various bit positions are:

1 : ERI (error indicator, bit inserted in the active maintenance cells to warn neighbour boards that an error is detected), 2 : P-FERF or RDI-P (path section far end received failure indication sent to the origin of the defect), 4 : MS-FERF or RDI-L (multiplexing section far end received failure indication sent to the origin of the defect), 8 : ATM-AIS (alarm indication signal is sent on a line defect towards the network handler dealing with VP/VC AIS management), 16 : RAI (remote alarm indication), 32 : RLED (the status led must be set permanent red).

What is adnAeiPortDefSignalling?

This OID is a bitmap that controls what additional defect signals are sent along with the standard alert to the control unit—for example, bit 1 enables ERI (error indicator) insertion in active maintenance cells. Network engineers enable or disable specific signal types to comply with carrier standards or to avoid overloading downstream alarm systems. A value of 3 might mean both ERI (bit 1) and P-FERF (bit 2) signalling are active.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.637.3.1.8.5.5.21.1.9
snmpwalk -v2c -c public <target> ADN-ENV-MIB::adnAeiPortDefSignalling

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.637.3.1.8.5.5.21.1.9.1
snmpget -v2c -c public <target> ADN-ENV-MIB::adnAeiPortDefSignalling.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.637.3.1.8.5.5.21.1.9.1 i <value>
