Module: Fore-SSM-MIB

OID (symbolic): Fore-SSM-MIB::syncStatusMsgSdhOption

OID (numeric): 1.3.6.1.4.1.326.2.2.2.1.21.3

What is syncStatusMsgSdhOption?

This read-write enumerated value, defaulting to optionII, selects which SSM option, Option I or Option II, is used on SDH/E1 interfaces. Admins set this to match the SSM signaling convention used by the connected SDH/E1 network equipment, since the two options are not interoperable. For example, an admin sets this to optionI(1) to match a European SDH network segment that uses the Option I SSM signaling scheme rather than the default Option II.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.326.2.2.2.1.21.3
snmpwalk -v2c -c public <target> Fore-SSM-MIB::syncStatusMsgSdhOption

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.326.2.2.2.1.21.3.1
snmpget -v2c -c public <target> Fore-SSM-MIB::syncStatusMsgSdhOption.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.326.2.2.2.1.21.3.1 i <value>
