s5AgSysSpanningTreePathCostCalculationMode

Module: S5-AGENT-MIB

OID (symbolic): S5-AGENT-MIB::s5AgSysSpanningTreePathCostCalculationMode

OID (numeric): 1.3.6.1.4.1.45.1.6.4.4.20

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This object indicates the current spanning-tree path cost calculation mode of the system. Note that this object can only take the value ieee802dot1dCompatible(1) if the value of s5AgSysSpanningTreeOperMode is currently avayaStpg(1).

What is s5AgSysSpanningTreePathCostCalculationMode?

Selects how spanning-tree path cost is calculated, ieee802dot1dCompatible(1) or ieee802dot1tCompatible(2); the older 802.1d-compatible mode can only be selected while s5AgSysSpanningTreeOperMode is currently set to the legacy avayaStpg(1) mode.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.45.1.6.4.4.20
snmpwalk -v2c -c public <target> S5-AGENT-MIB::s5AgSysSpanningTreePathCostCalculationMode

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.45.1.6.4.4.20.1
snmpget -v2c -c public <target> S5-AGENT-MIB::s5AgSysSpanningTreePathCostCalculationMode.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.45.1.6.4.4.20.1 i <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> s5AgSysSpanningTreePathCostCalculationMode.1
