Description: Provides management objects for configuring and managing Fibre Channel device aliases (human-readable names for WWNs) on Cisco MDS switches.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CISCO-FC-DEVICE-ALIAS-MIB?

CISCO-FC-DEVICE-ALIAS-MIB manages Fibre Channel device aliases on Cisco MDS SAN switches, letting administrators assign human-readable names to the cryptic 8-byte World Wide Names (WWNs) used to identify disks, hosts, and switches in a Fibre Channel fabric. It exposes configuration data mapping a device alias to a device type, device ID (WWN), and row status for creating/deleting alias entries. This is a configuration/naming MIB rather than a fault or performance MIB, so its monitoring value is in verifying that device aliases are correctly and consistently provisioned across the fabric so that other management tools display meaningful names instead of raw WWNs. It is Fibre Channel fabric-specific and works alongside other Cisco FC management MIBs but has no dependency on general IETF standards beyond basic SNMP conventions. It is deployed on Cisco MDS 9000 series Fibre Channel SAN switches, and administrators can perform a CISCO-FC-DEVICE-ALIAS-MIB download to load its object definitions directly into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-FC-DEVICE-ALIAS-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Monitoring Examples

An administrator would walk cfdaConfigTable/cfdaConfigEntry to confirm each cfdaConfigDeviceAlias maps to the expected cfdaConfigDeviceId (WWN) and cfdaConfigDeviceType, and check cfdaConfigRowStatus to verify an alias entry is active rather than left in a notReady state. A missing or mismatched alias entry would explain why a host or disk appears unnamed in fabric-wide management views.

OIDs

OID symbolic	OID numeric	Type	Access	Description
ciscoFcDeviceAliasMIB	1.3.6.1.4.1.9.9.430			The MIB module for the management of Device Aliases in a Fibre Channel Fabric. A Fibre Channel fabric consists of devices such as disks, hosts and switches. The disks and hosts login to the switches and avail services available to them in the fabric. These devices are identified by means of their World Wide Names (WWN). The WWNs are 8-byte cryptic identifiers, which are cumbersome for human use. A Device Alias is a human readable string which can be used to alias a World Wide Name (WWN). So, a Device Alias is used to map a WWN to a user friendly name. Once configured, the Device Alias can be used in place of the WWN. On the switch, this MIB assists in defining the Device Aliases for the remote devices and using these Aliases instead of the cryptic WWNs.
cfdaMIBNotifs	1.3.6.1.4.1.9.9.430.0
cfdaMIBObjects	1.3.6.1.4.1.9.9.430.1
cfdaConfiguration	1.3.6.1.4.1.9.9.430.1.1
cfdaConfigTable	1.3.6.1.4.1.9.9.430.1.1.1		not-accessible	A table containing information on all device aliases that have been configured on the local switch.
cfdaConfigEntry	1.3.6.1.4.1.9.9.430.1.1.1.1		not-accessible	Each entry in this table contains the mapping between the alias for a Fibre Channel device and its World Wide Name (WWN).
STR cfdaConfigDeviceAlias	1.3.6.1.4.1.9.9.430.1.1.1.1.1	SnmpAdminString	not-accessible	The device alias of this entry. This object is the human friendly string for the device represented by the corresponding instance of cfdaConfigDeviceWwn. A device can have only one alias configured. The value of this object MUST begin with an alphabet.
CDP cfdaConfigDeviceType	1.3.6.1.4.1.9.9.430.1.1.1.1.2	CdpvmDevType	read-create	The type of the Fibre Channel device represented by the corresponding instance of cfdaConfigDeviceId. This object cannot be modified while the value of the corresponding instance of cfdaConfigRowStatus is 'active'.
OCT cfdaConfigDeviceId	1.3.6.1.4.1.9.9.430.1.1.1.1.3	OCTET STRING	read-create	The Fibre Channel device which is given a device alias as indicated by the corresponding instance of cfdaConfigDeviceAlias. This object MUST be set to a valid value before or concurrently with setting the corresponding instance of cfdaConfigRowStatus object to 'active'. This object cannot be modified while the value of the corresponding instance of cfdaConfigRowStatus object is 'active'.
ROW cfdaConfigRowStatus	1.3.6.1.4.1.9.9.430.1.1.1.1.4	RowStatus	read-create	The status of this conceptual row. Before setting this object to 'active', the corresponding instance of cfdaConfigDeviceId MUST be set to a valid value. None of the objects can be modified while the value of this object is 'active'.
cfdaMIBConform	1.3.6.1.4.1.9.9.430.2

ciscoFcDaMIBCompliance	1.3.6.1.4.1.9.9.430.2.1.1			The compliance statement for entities which implement Device Aliases.
ciscoFcDaMIBGroups	1.3.6.1.4.1.9.9.430.2.2
ciscoFcDaConfigGroup	1.3.6.1.4.1.9.9.430.2.2.1			A collection of objects for configuring and distributing device aliases.
