CM Attributes

Refer to Table 36-3 on page 1072. With the exception of the ClassPortInfo attribute, the remainder of the attributes are actually the various types of CM messages (e.g., REQ, REP, RTU, etc.). A CA's CM sends a CM MAD by transmitting a ComMgtSend(attribute) MAD, where the message is the attribute contained in the attribute data area (dwords 6 through 63 in Table 36-1 on page 1070).

AttributeAttribute IDDescription
None of the CM attributes use a modifier.
ClassPortInfo0001hPresence of ClassPortInfo for a management class (see Table 28-7 on page 794) confirms availability of that management class on a CA, switch, or router. ClassPortInfo provides:

  • Indication of port's ability to generate traps and notices.

  • Port's RespTimeValue.

  • If port's CM requires redirection of CM MADs, address to be redirected to is supplied (GID, LID, QP, etc.).

  • If port's CM supports traps, address to which traps are delivered is supplied (GID, LID, etc.).

  • Whether multicast, RC, RD, or Raw QPs are supported.

The following CM-specific ClassPortInfo.CapabilityMask bits are implemented:

  • Bit 8 = IsMulticastCapable. 1 = Multicast is suported.

  • Bit 9 = IsReliableConnectionCapable. 1 = RC QPs are supported.

  • Bit 10 = IsReliableDatagramCapable. 1 = RD QPs are supported.

  • Bit 11 = IsRawDatagramCapable. 1 = Raw QPs are supported.
