isisSysLevelSetOverloadUntil

Module: ISIS-MIB

OID (symbolic): ISIS-MIB::isisSysLevelSetOverloadUntil

OID (numeric): 1.3.6.1.2.1.138.1.2.1.1.6

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-write

Description: If this object is non-zero, the overload bit is set at this level when the isisSysAdminState variable goes to state 'on' for this Intermediate System. The overload bit remains set for isisSysLevelSetOverloadUntil seconds. When isisSysLevelSetOverloadUntil seconds have elapsed, the overload flag remains set if the implementation has run out of memory, or if it is set manually using the isisSysLevelSetOverload object.

If isisSysLevelSetOverload is false, the system clears the overload bit when isisSysLevelSetOverloadUntil seconds have elapsed, if the system has not run out of memory.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.138.1.2.1.1.6
snmpwalk -v2c -c public <target> ISIS-MIB::isisSysLevelSetOverloadUntil

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.138.1.2.1.1.6.1
snmpget -v2c -c public <target> ISIS-MIB::isisSysLevelSetOverloadUntil.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.2.1.138.1.2.1.1.6.1 i <value>
