Description: Provides management objects for configuring and monitoring Fibre Channel multicast distribution trees and group membership on Cisco SAN 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-MULTICAST-MIB?

CISCO-FC-MULTICAST-MIB is a Cisco Systems proprietary MIB configuring and monitoring the Fibre Channel Multicast feature on Cisco MDS/Nexus SAN switches. Its multicast-root table, keyed by VSAN, records the configured and operational multicast-root mode, the domain ID acting as multicast root, and row status. As a configuration/status MIB it lets a SAN administrator confirm which switch is currently the Fibre Channel multicast root for a given VSAN. It is deployed on Cisco MDS/Nexus Fibre Channel SAN switches. Engineers can download the CISCO-FC-MULTICAST-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-FC-MULTICAST-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.

Supported Devices

Cisco MDS/Nexus Fibre Channel SAN switches

Monitoring Examples

A SAN administrator checks cfmMulticastRootDomainId to confirm which switch is currently serving as the Fibre Channel multicast root for a VSAN.

OIDs

OID symbolic	OID numeric	Type	Access	Description
ciscoFcMulticastMIB	1.3.6.1.4.1.9.9.435			MIB module for monitoring and configuring Fibre Channel Multicast feature.
ciscoFcMulticastNotifications	1.3.6.1.4.1.9.9.435.0
ciscoFcMulticastMIBObjects	1.3.6.1.4.1.9.9.435.1
cfmConfiguration	1.3.6.1.4.1.9.9.435.1.1
cfmMulticastRootTable	1.3.6.1.4.1.9.9.435.1.1.1		not-accessible	This table allows the users to configure and monitor the FC Multicast parameters on all the VSANs configured on the local switch. An entry is automatically created in this table if there is an entry in the fspfTable (defined in CISCO-FSPF-MIB) and fspfOperStatus (defined in CISCO-FSPF-MIB) for that entry is 'up'. An entry is automatically deleted from this table if either : a) the fspfOperStatus in the fspfTable entry for the corresponding VSAN changes to 'down'. or b) the fspfTable entry for the corresponding VSAN is deleted. Entries in this table can be created via cfmMulticastRootRowStatus only as the means to specify non-default parameter values for a VSAN either because the VSAN is suspended or fspfOperStatus (defined in CISCO-FSPF-MIB) for that VSAN is 'down' (VSAN state is indicated by object vsanOperState which is defined in CISCO-VSAN-MIB). So an entry in this table exists when one or both of these conditions holds: - one or more configuration parameters have non-default values for a VSAN which is either suspended or the fspfOperStatus for that VSAN is down. - the fspfOperStatus for VSAN is 'up'. This has a number of consequences: - an entry exists for a suspended VSAN whenever that VSAN has non-default parameters. - an entry cannot be created (via cfmMulticastRootRowStatus) for a VSAN with default parameters; instead, the agent creates/deletes an entry for a VSAN with default parameters according to whether the fspfOperStatus is 'up' or 'down'. - an entry can not be created via cfmMulticastRootRowStatus unless non-default parameter values are (simultaneously) configured for a VSAN whose fspfOperStatus is 'down'. - deleting an entry via cfmMulticastRootRowStatus when either the VSAN is suspended and configured with non-default values or the VSAN is active, is equivalent to resetting its parameters to their default values. If an entry is configured with default-values and the VSAN is in suspended state, then the entry would be deleted.
cfmMulticastRootEntry	1.3.6.1.4.1.9.9.435.1.1.1.1		not-accessible	This entry contains the multicase parameters on this VSAN.
CFM cfmMulticastRootConfigMode	1.3.6.1.4.1.9.9.435.1.1.1.1.1	CfmMulticastRootMode	read-create	The configured multicast root mode on this VSAN.
CFM cfmMulticastRootOperMode	1.3.6.1.4.1.9.9.435.1.1.1.1.2	CfmMulticastRootMode	read-only	The operational multicast root mode on this VSAN.
DOM cfmMulticastRootDomainId	1.3.6.1.4.1.9.9.435.1.1.1.1.3	DomainIdOrZero	read-only	The domainID of the multicast root on this VSAN.
ROW cfmMulticastRootRowStatus	1.3.6.1.4.1.9.9.435.1.1.1.1.4	RowStatus	read-create	The status of conceptual row on this VSAN. This object can be used to create an entry only if either the corresponding VSAN is suspended or the fspfOperStatus is down. If the VSAN is either not-existent or fspfOperStatus is up, the create will fail.
