What is fcmPortWwn?
This object stores the World Wide Name (WWN) identifier of a Fibre Channel port, or an empty string if the port does not have a WWN assigned. The WWN uniquely identifies the port within the entire Fibre Channel fabric, similar to a MAC address in Ethernet. Operators use this to correlate SNMP monitoring with Fibre Channel fabric management tools and verify port identity in SAN environments.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.10.56.1.3.1.2 snmpwalk -v2c -c public <target> FC-MGMT-MIB::fcmPortWwn
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.10.56.1.3.1.2.1 snmpget -v2c -c public <target> FC-MGMT-MIB::fcmPortWwn.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> fcmPortWwn.1
