hh3cVsanDmFabricChangeNotify
Module: HH3C-VSAN-MIB
OID (symbolic): HH3C-VSAN-MIB::hh3cVsanDmFabricChangeNotify
OID (numeric): 1.3.6.1.4.1.25506.2.127.1.1.3.0.3
Node type: NOTIFICATION-TYPE
Description:
This event will be triggered if a switch sends or receives a Build Fabric (BF) or a Reconfigure Fabric (RCF) message in a VSAN.
The conditions a switch can receive or send a BF or a RCF are listed as follows: 1. Two isolated fabrics in a VSAN merge into one fabric. If the Domain ID lists do not overlap, the sent or received message is BF, other cases, it is RCF. 2. If an upstream principal link which connects to principal switch and other switches become disconnected, the sent or received message is BF. 3. A BF or RCF process is triggered manually by configuration.
The notification contains the index of the VSAN in which a BF or a RCF was sent or received.
What is hh3cVsanDmFabricChangeNotify?
This OID is an alert triggered when a Fibre Channel fabric undergoes topology changes like merging isolated networks or reconfiguring domain IDs within a virtual SAN. This notification tells you that significant fabric restructuring occurred and may affect connectivity. A Fibre Channel administrator receives this alert to investigate configuration changes or diagnose unexpected fabric rebuilds.
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> '' HH3C-VSAN-MIB::hh3cVsanDmFabricChangeNotify snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.25506.2.127.1.1.3.0.3
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
