ieee8021SpbmTopNodeEntrySPsourceID

Module: IEEE8021-SPB-MIB

OID (symbolic): IEEE8021-SPB-MIB::ieee8021SpbmTopNodeEntrySPsourceID

OID (numeric): 1.3.111.2.802.1.1.26.1.8.1.4

Node type: OBJECT-TYPE

Type: IEEE8021SpbmSPsourceId

Access: read-only

Description: The Shortest Path Source Identifier. It is the high order 3 bytes for Group Address DA from this bridge. Note that only the 20 bits not including the top 4 bits are the SPSourceID.

What is ieee8021SpbmTopNodeEntrySPsourceID?

The 20-bit Shortest Path Source Identifier reported for a remote node in the SPB topology, letting an admin see how multicast trees rooted at that node are addressed from this bridge's perspective.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.26.1.8.1.4
snmpwalk -v2c -c public <target> IEEE8021-SPB-MIB::ieee8021SpbmTopNodeEntrySPsourceID

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.26.1.8.1.4.1
snmpget -v2c -c public <target> IEEE8021-SPB-MIB::ieee8021SpbmTopNodeEntrySPsourceID.1
