swMSTPInstExternalRootCost
Module: MSTP-MIB
OID (symbolic): MSTP-MIB::swMSTPInstExternalRootCost
OID (numeric): 1.3.6.1.4.1.171.12.15.2.3.1.14
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The path cost between MST Regions from the transmitting Bridge to the CIST Root. For MST instance this object is unused.
What is swMSTPInstExternalRootCost?
This read-only value reports the path cost, measured between MST Regions, from this bridge to the CIST Root; it's unused for MST instances and only meaningful for the CIST. Admins use it on instance 0 to gauge how many region-hops away the CIST root is.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.15.2.3.1.14 snmpwalk -v2c -c public <target> MSTP-MIB::swMSTPInstExternalRootCost
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.15.2.3.1.14.1 snmpget -v2c -c public <target> MSTP-MIB::swMSTPInstExternalRootCost.1
