slEntPhysicalProtectionEntity

Module: SL-ENTITY-MIB

OID (symbolic): SL-ENTITY-MIB::slEntPhysicalProtectionEntity

OID (numeric): 1.3.6.1.4.1.4515.1.3.6.1.1.1.8

Node type: OBJECT-TYPE

Type: PhysicalIndex

Access: read-only

Description: The value of slEntPhysicalIndex for the physical entity which 'protects' this physical entity. A value of zero indicates this physical entity has no protecting physical entity. This object is not applicable should the protection be done on a per-port basis.

What is slEntPhysicalProtectionEntity?

This value gives the slEntPhysicalIndex of the physical entity that acts as this one's protection partner, or zero if there is no protecting entity. Admins use it to trace which standby card would take over if this card fails, important when planning a card swap without causing an outage. For example, a value of 9 on the active switch module would point to a standby switch module at index 9 as its protector.
