wwnmSecondaryBaseMacAddress
Module: CISCO-WWNMGR-MIB
OID (symbolic): CISCO-WWNMGR-MIB::wwnmSecondaryBaseMacAddress
OID (numeric): 1.3.6.1.4.1.9.9.286.1.1.1
Node type: OBJECT-TYPE
Type: MacAddress
Access: read-write
Description: The first MAC address used for generating World Wide Names (WWNs) when the default range of WWNs generated from supervisor MAC address are exhausted.
What is wwnmSecondaryBaseMacAddress?
This read-write object sets the first MAC address to be used as the base for generating World Wide Names once the default WWN range derived from the supervisor's own MAC address has been exhausted. An admin configures this to give the switch a fallback pool of WWN-generation material for a fabric that has outgrown its original allocation. For example, on a large storage fabric with many VSANs and virtual devices, an admin might need to set wwnmSecondaryBaseMacAddress once the supervisor-derived WWN pool runs out of unique identifiers to assign.
