Module: ISIS-MIB

OID (symbolic): ISIS-MIB::isisCircLevelHelloTimer

OID (numeric): 1.3.6.1.2.1.138.1.4.1.1.9

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-write

Description: Maximum period, in milliseconds, between IIH PDUs on multiaccess networks at this level for LANs. The value at L1 is used as the period between Hellos on L1L2 point-to-point circuits. Setting this value at level 2 on an L1L2 point-to-point circuit will result in an error of InconsistentValue.

This object follows the ResettingTimer behavior.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.138.1.4.1.1.9
snmpwalk -v2c -c public <target> ISIS-MIB::isisCircLevelHelloTimer

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.138.1.4.1.1.9.1
snmpget -v2c -c public <target> ISIS-MIB::isisCircLevelHelloTimer.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.2.1.138.1.4.1.1.9.1 i <value>
