dmFabricChangeNotify
Module: CISCO-DM-MIB
OID (symbolic): CISCO-DM-MIB::dmFabricChangeNotify
OID (numeric): 1.3.6.1.4.1.9.9.302.1.3.0.3
Node type: NOTIFICATION-TYPE
Description: This notification is sent whenever a switch sends or receives a Build Fabric (BF) or a ReConfigure Fabric (RCF) message on a VSAN.
A switch can receive or issue a BuildFabric (BF) or a ReConfigureFabric (RCF) message under following conditions: - A new link causes two disjoint fabrics in a VSAN to merge into one fabric. The sent/received message is BF if the Domain ID lists on the disjoint fabric does not overlap and it is RCF if they overlap. - An upsteam principal ISL which connects to Principal switch and other switches in a VSAN fails. BF is issued to see if there is an alternative path to the Principal Switch. If not paths exit, then an RCF is issued. - A switch asks for a different set of Domain IDs than the currently assigned list, the Principal switch would issue an RCF.
The notification is not sent if a 'dmNewPrincipalSwitchNotify' notification is sent for the same transition. This notification contains the vsanIndex of the VSAN on which RCF was issued.
Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' CISCO-DM-MIB::dmFabricChangeNotify snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.9.9.302.1.3.0.3
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
Example snmptrapd log entry:
zoo11-linux.zoo [UDP: [192.168.30.111]:56123->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (357736251) 41 days, 9:42:42.51 SNMPv2-MIB::snmpTrapOID.0 = OID: CISCO-DM-MIB::dmFabricChangeNotify
