sonetPathAis

Module: Fore-SONET-MIB

OID (symbolic): Fore-SONET-MIB::sonetPathAis

OID (numeric): 1.3.6.1.4.1.326.2.2.1.1.4.1.1.1.20

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This variable controls the insertion of STS Path Alarm Indication Signal (AIS_P). When set to sonetPathAisOn, the complete SPE, and the pointer bytes (H1, H2, and H3) are overwritten with the all ones pattern. When set to sonetPathAisOff, the pointer bytes and the SPE are processed normally.

What is sonetPathAis?

Controls whether this port inserts a STS Path Alarm Indication Signal, overwriting the SPE and pointer bytes (H1/H2/H3) with an all-ones pattern when set to sonetPathAisOn. An admin uses this to signal a path-layer failure downstream during testing, similar in purpose to sonetLineAis at the line layer.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.326.2.2.1.1.4.1.1.1.20
snmpwalk -v2c -c public <target> Fore-SONET-MIB::sonetPathAis

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.326.2.2.1.1.4.1.1.1.20.1
snmpget -v2c -c public <target> Fore-SONET-MIB::sonetPathAis.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.326.2.2.1.1.4.1.1.1.20.1 i <value>
