End-to-end performance monitoring
End-to-end performance monitoring counts the number of words in Fibre Channel frames for a specified
Source ID (SID) and Destination ID (DID) pair. An end-to-end performance monitor includes these counts:
• RX_COUNT (words in frames received at the port)
• TX_COUNT (words in frames transmitted from the port)
To enable end-to-end performance monitoring, you must configure an end-to-end monitor on a port,
specifying the SID-DID pair (in hexadecimal). The monitor counts only those frames with matching the SID
and DID.
Each SID or DID has the following three fields.
• Domain ID (DD)
• Area ID (AA)
• AL_PA (PP)
For example, the SID 0x118a0f denotes DD 0x11, AA 0x8a, and AL_PA 0x0f.
