HELP: GROUP/VF CATEGORY STATS SCREEN

Category Stats for a port group/VF are divided into up to two subgroups -

Internal or External - based on whether a port's neighbor port is in its group

(Internal) or not (External).  In the All group all ports are Internal. For

example in the HFIs group all ports are External. In the SWs group ports may be

Internal or External.  The six categories are based on mapping each port

counter into one of the categories as follows. The integrity and congestion

counter values are calculated by using a weighted sum. The weights for each

and the threshold value for each category can be seen in the PM Config screen.

Some counters are gathered from the neighbor's port instead.

 Integrity:

  Local Link Integrity Errors

  Port Receive Errors

  Excessive Buffer Overrun Errors (neighbor port)

  Link Error Recovery

  Link Downed

  Uncorrectable Errors

  FM Config Errors

 Congestion:

  Port Transmit Wait

  Switch Port Congestion

  Port Receive FECN (neighbor port)

  Port Receive BECN (only from FIs)

  Port Transmit Time Congestion

  Port Mark FECN

 SmaCongestion:

  The counters included in the SMA Congestion category are the VL 15 counters

  equivalent to the port counters in the Congestion category.

 Bubble:

  Port Transmit Wasted Bandwidth

  Port Transmit Wait Data

  Port Receive Bubble (neighbor port)

 Security:

  Port Receive Constraint Errors (neighbor port)

  Port Transmit Constraint Errors

 Routing:

  Port Receive Switch Relay Errors

For each subgroup within a category, there are five histogram buckets. Each

bucket has a width of 25%(0+%, 25+%, etc) and the last bucket for over the

threshold(100+%). A bucket is used to measure the number of ports whose category

value when compared to the threshold falls within the range of the bucket. This

provides an indication of how counter rates compare to their thresholds.

The Ctg Stats screen accepts input commands which specify parameters to be

used in a group focus query, which will provide a list of ports sorted

according to a specified category criterion. The second line of the Ctg Stats

screen displays the group name, and the currently selected focus criterion

and number of ports for a group focus query.  The 'D' command causes the group

focus query to be performed and displayed in a Group Focus screen.  The

following input commands are accepted in the Ctg Stats screen.

  C: Select group focus criterion forward (c*) or reverse (C*):

     Integrity category (highest first)

     Congestion category (highest first)

     SmaCongestion category (highest first)

     Bubble category (highest first)

     Security category (highest first)

     Routing category (highest first)

  Nn: Number of entries n in group focus list

  D:  Display detail group focus list
