usdIsisSysID

Module: Unisphere-Data-ISIS-MIB

OID (symbolic): Unisphere-Data-ISIS-MIB::usdIsisSysID

OID (numeric): 1.3.6.1.4.1.4874.2.2.38.1.1.1.1.4

Node type: OBJECT-TYPE

Type: SystemID

Access: read-write

Description: The ID for this instance of the Integrated IS-IS protocol. This value is appended to each of the instance's area addresses to form the Network Entity Titles valid for this instance. The derivation of a value for this object is implementation-specific. Some implementations may assign values and not permit write MAX-ACCESS, others may require the value to be set manually.

What is usdIsisSysID?

Sets the System ID for this IS-IS instance, which combines with configured area addresses to form the router's Network Entity Titles (NETs). An admin assigns a unique System ID, often derived from a loopback MAC or IP, to identify this router in the IS-IS domain.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4874.2.2.38.1.1.1.1.4
snmpwalk -v2c -c public <target> Unisphere-Data-ISIS-MIB::usdIsisSysID

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.4874.2.2.38.1.1.1.1.4.1
snmpget -v2c -c public <target> Unisphere-Data-ISIS-MIB::usdIsisSysID.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.4874.2.2.38.1.1.1.1.4.1 s <value>
