e1T1InputSSMStateV1

Module: SYMME1T1

OID (symbolic): SYMME1T1::e1T1InputSSMStateV1

OID (numeric): 1.3.6.1.4.1.9070.1.2.5.2.2.1.2.1.1.4

Node type: OBJECT-TYPE

Type: EnableValue

Access: read-write

Description: SSM enable state. It can be Enable (1) or Disable (2). Disabling the SSM means the incoming SSM is not used, and the forced (default) PQL value for this input port will be used during the reference selection. SSM is supported for only three frame types: EFS, CAS with CRC4, and CCA with CRC4. SSM should not be enabled for other frame types. If SSM is enabled for an input port, but the frame type does not support SSM or is not sending a valid SSM, then this input will be disqualified and the input PQL will be set to 'invalid.' The system will go into holdover no other qualified reference is available.

What is e1T1InputSSMStateV1?

This object enables or disables use of the incoming SSM (Synchronization Status Message) on this input port, only supported for ESF, CAS with CRC4, and CCS with CRC4 framing; when disabled, the port instead uses its forced default PQL value. Admins disable SSM on ports whose upstream source doesn't send valid SSM, since leaving it enabled for an unsupported frame type causes the input to be disqualified and go to PQL 'invalid.' Enabling this on an ESF-framed input lets the system automatically rank that port's quality from the SSM it receives, rather than relying on a manually assigned PQL value.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9070.1.2.5.2.2.1.2.1.1.4

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9070.1.2.5.2.2.1.2.1.1.4.1
snmpget -v2c -c public <target> SYMME1T1::e1T1InputSSMStateV1.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.9070.1.2.5.2.2.1.2.1.1.4.1 s <value>
