swL2StpPortAdminPathCost
Module: DES3026-L2MGMT-MIB
OID (symbolic): DES3026-L2MGMT-MIB::swL2StpPortAdminPathCost
OID (numeric): 1.3.6.1.4.1.171.11.63.3.2.16.4.1.12
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: The administratively assigned value for the contribution of this port to the path cost of paths towards the spanning tree root.
Writing a value of '0' assigns the automatically calculated default Path Cost value to the port. If the default Path Cost is being used, this object returns '0' when read.
This complements the object swL2StpPortPathCost, which returns the operational value of the path cost.
Issue No.: 3250R2-077 As USE_RSTP is 1:enabled, swL2StpPortPathCost is forced to be read-only. configuration via swL2StpPortAdminPathCost. According 802.1w, value range of swL2StpPortAdminPathCost would be expanded. the former value range is (0..65535), the new is (0..200000000).
What is swL2StpPortAdminPathCost?
Sets the administrative STP path cost contributed by this port toward the root bridge; writing 0 makes the switch use its own automatically calculated default cost instead of a fixed value, in which case reading this object back also returns 0. Admins override the auto-calculated cost here to manually influence which redundant path STP prefers, for example forcing traffic onto a preferred higher-bandwidth uplink.
