fscSerialTrapObjectAggregateServerStatusChanged
Module: FSCSERIAL-TRAP-MIB
OID (symbolic): FSCSERIAL-TRAP-MIB::fscSerialTrapObjectAggregateServerStatusChanged
OID (numeric): 1.3.6.1.4.1.544.8.2.6.18
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: This object is sent in a trap to report server session status changes and power status changes. This object will report the status for all connection paths known to the appliance in an aggregated encoding format as indicated below.
The information for each connection path is packed into four bytes as follows:
Byte 1 = The serial port number associated with this path.
Byte 2 = The enumerated socket number of the SPC cascade device associated with this connection path. The value will be 0 if an SPC socket is not associated with this connection path.
The socket number enumeration will use this convention:
A1 = 1 C1 = 9 A2 = 2 C2 = 10 A3 = 3 C3 = 11 A4 = 4 C4 = 12 B1 = 5 D1 = 13 B2 = 6 D2 = 14 B3 = 7 D3 = 15 B4 = 8 D4 = 16
No SPC attached = 0
Byte 3 = The power status of a connected server or the power status of an SPC socket. One of the following values can be reported:
1 = unknown - unable to determine the power status.
2 = on - the server or the SPC socket is powered on.
3 = off - the server or the SPC socket is powered off.
Byte 4 = The serial session status. One of the following values can be reported:
1 = N/A - not applicable when an SPC is attached.
2 = Idle - there is no active viewer session on this path.
3 = Active - there is an active viewer session currently on this path.
Each connection path will be packed into this object in four byte increments one after the other. The connection paths do not have to be packed in any specific order.
Note that the size of this object could conceivably be as large as shown in the following calculation assuming a 16 socket SPC were connected to each serial port of the appliance:
48 ports X 16 sockets X 4 bytes = 3072 bytes.
What is fscSerialTrapObjectAggregateServerStatusChanged?
This object is the payload carried in a trap sent by an FSC serial console appliance whenever a connected server's session or power status changes, packing the status of every known serial connection path into 4-byte groups (serial port number, attached power-controller socket, power state, and console session activity). Admins or monitoring tools parse this byte-packed structure to see, in a single trap, which serial ports have servers that just powered on or off or gained/lost an active console viewer, instead of receiving dozens of separate alerts. For example, on a fully populated 48-port appliance with 16-socket power controllers on every port, this object could grow to 3072 bytes (48 x 16 x 4) to describe every connection path at once.
