Troubleshooting Licensing
Licensing functionality is available in all switches in the Cisco MDS 9000 Family. This functionality
allows you to access specified premium features on the switch after you install the appropriate license
for that feature. Licenses are supported, and enforced in Cisco MDS SAN-OS Release 1.3(1) and later.
This chapter includes the following topics:
• License Overview, page 6-1
• Initial Troubleshooting Checklist, page 6-3
• Licensing Installation Issues, page 6-6
License Overview
Cisco SAN-OS requires licenses for advanced features. These licenses have two options:
• Feature-based licensing—Features that are applicable to the entire switch. You need to purchase and
install a license for each switch that uses the features you are interested in. The Enterprise license
is an example of a feature-based license.
• Module-based licensing—Features that require additional hardware modules. You need to purchase
and install a license for each module that uses the features you are interested in. The SAN Extension
over IP license is an example of a module-based license.
Note The Cisco MDS 9216i switch enables SAN Extension features on the two fixed IP services ports only.
The features enabled on these ports are identical to the features enabled by the SAN Extension over IP
license on the14/2-port Multiprotocol Services (MPS-14/2) module. If you install a module with IP ports
in the empty slot on the Cisco MDS 9216i, a separate SAN Extension over IP license is required to enable
related features on the IP ports of the additional module.
