foreSonetLineDiagnosticsK2Mode

Module: Fore-Sonet-Ext-MIB

OID (symbolic): Fore-Sonet-Ext-MIB::foreSonetLineDiagnosticsK2Mode

OID (numeric): 1.3.6.1.4.1.326.2.2.1.1.14.3.3.1.8

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Bits 6 through 8 of the K2 byte shall be set to indicate: � Code '101' if the provisioned mode is bidirectional � Code '100' if the provisioned mode is unidirectional The codes '011', '010', '001' and '000' in K2 bites 6-8 are reserved for future use in 1:n drop and insert(nested) protection switching, and the code '111' is used in detecting an incoming AIS_L.

What is foreSonetLineDiagnosticsK2Mode?

Sets bits 6-8 of the transmitted K2 byte to declare the port's APS signaling mode: unidirectional or bidirectional. This determines whether protection switches are coordinated in both directions with the far end or handled independently on each end.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.326.2.2.1.1.14.3.3.1.8
snmpwalk -v2c -c public <target> Fore-Sonet-Ext-MIB::foreSonetLineDiagnosticsK2Mode

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.326.2.2.1.1.14.3.3.1.8.1
snmpget -v2c -c public <target> Fore-Sonet-Ext-MIB::foreSonetLineDiagnosticsK2Mode.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.326.2.2.1.1.14.3.3.1.8.1 i <value>
