Cisco Fiber Channel (FC) port channels are dependent on the Organizationally Unique Identifiers (OUIs) of the devices at each
end of the port channels for successful configuration. When new devices are released or new OUI ranges are assigned to existing
devices due to OUI pool depletion, the new OUIs need to be added to their respective OUI tables for the port channel to be
configured successfully.
Adding an OUI
To establish FC port-channels with new Cisco FC devices or devices with newly assigned OUI ranges, you can manually add OUIs
into the database using the following command through Cisco UCSM CLI:
FI-A # sc fabric-interconnect {a|b}
FI-A /fabric-interconnect # sc oui-pool default
FI-A /fabric-interconnect/oui-pool # sh oui
FI-A /fabric-interconnect/oui-pool # create oui [oui-id]
FI-A /fabric-interconnect/oui-pool/oui* # commit-buffer
Where, oui-id
is the new OUI of the device that needs to be added. The device OUI must be an eight digit hexadecimal number. The valid
range of OUI is from 0x000000 to 0xffffff. For example, 0xabcdef.
Viewing OUIs
To view the list of OUIs, run the following command:
FI-A /fabric-interconnect/oui-pool# show oui
The following example shows the sample output of the show oui
command:
FI-A /fabric-interconnect/oui-pool# show oui
OUI Entry:
Oui
---
0x0001ac
0x1b0000
0xaabbcc
0xddeeff
Deleting an OUI
To delete an OUI, run the following command:
FI-A /fabric-interconnect/oui-pool# delete ouientry [oui-id]
Where, oui-id is the OUI of the device that needs to be deleted.
