juniIsisSysReferenceBandwidth

Module: Juniper-ISIS-MIB

OID (symbolic): Juniper-ISIS-MIB::juniIsisSysReferenceBandwidth

OID (numeric): 1.3.6.1.4.1.4874.2.2.38.1.1.1.1.44

Node type: OBJECT-TYPE

Type: Gauge32

Access: read-write

Description: Configure the reference bandwitdth used to calculate the link cost in bits per second.If the reference bandwidth is greater than the maximum value reportable by this object then this object should report its maximum value (4,294,967,295) and juniIsisSysHighReferenceBandwidth must be used to report the reference bandwidth.

What is juniIsisSysReferenceBandwidth?

Read-write Gauge32 setting the reference bandwidth (in bits per second) IS-IS uses to compute default link costs; if the true reference bandwidth exceeds the 4,294,967,295 max this field can hold, juniIsisSysHighReferenceBandwidth must be used instead. Admins raise this on networks with very high-speed links so cost differences between, say, 10G and 100G interfaces remain meaningful.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4874.2.2.38.1.1.1.1.44
snmpwalk -v2c -c public <target> Juniper-ISIS-MIB::juniIsisSysReferenceBandwidth

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.4874.2.2.38.1.1.1.1.44.1
snmpget -v2c -c public <target> Juniper-ISIS-MIB::juniIsisSysReferenceBandwidth.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.4874.2.2.38.1.1.1.1.44.1 i <value>
