The WWN is printed on the LED side of both cards. 1. License Identifier (License ID) There is only one License Identifier associated with a physical switch or director/backbone chassis. This License Identifier is required as part of the ordering process for new FOS licenses. Use the licenseIdShow command to display the License Identifier.
