acSysTDMClockMasterSlaveSelection

Module: AC-SYSTEM-MIB

OID (symbolic): AC-SYSTEM-MIB::acSysTDMClockMasterSlaveSelection

OID (numeric): 1.3.6.1.4.1.5003.9.10.10.1.2.1.4

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Sets SC/MVIP/H.100/H.110 to either:

0 = Slave mode (another board in the system must supply the clock to the TDM bus) or Master mode (the board is the clock source for the TDM bus) or Secondary Master mode (for H100/H110 Bus only). 1 = H110A Master in Master mode 2 = H.110B Master. Access: Online. AC INI-Param: TDMBUSMASTERSLAVESELECTION

What is acSysTDMClockMasterSlaveSelection?

This OID defines the board's role in TDM clock distribution: 0 (Slave—receives clock from another board), 1 (H110A Master), or 2 (H.110B Master). Network designers use this to designate which board generates the master clock signal while others synchronize to it. Setting this to 1 makes the board the master clock source that all other boards will synchronize to over the H.110A bus.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5003.9.10.10.1.2.1.4
snmpwalk -v2c -c public <target> AC-SYSTEM-MIB::acSysTDMClockMasterSlaveSelection

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.5003.9.10.10.1.2.1.4.1
snmpget -v2c -c public <target> AC-SYSTEM-MIB::acSysTDMClockMasterSlaveSelection.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.5003.9.10.10.1.2.1.4.1 i <value>
