To use the SME feature, you need the appropriate SME license. However, enabling SME without a license key starts a counter on the grace period. You then have 120 days to install the appropriate license keys or disable the use of SME. If at the end of the 120-day grace period the switch does not have a valid license key for SME, it will be automatically disabled.
Note Although you need to install DCNM-SAN, you do not need a DCNM-SAN license to use SME. Additional DCNM-SAN capabilities are not enabled by default with SME, so there is no free performance monitoring or other functionality.
To identify if the SME feature is active, use the show license usage license-name command.
The Cisco MDS 9000 SME package is licensed on a per-encryption-engine basis. The total number of licenses needed for a SAN fabric is equal to the number of Cisco MDS 9000 18/4-Port Multiservice Modules plus the number of fixed slots on Cisco MDS 9222i switches used for SME plus the number of encryption engines on Cisco MDS 9000 16-Port Storage Services Nodes (SSN-16).
Each interface in the SSN-16 module is licensed and priced individually.
Table 1-1 lists the SME licenses that are available.
The following table shows the licensing requirements for this feature:
