Aggregated TM VOQ statistics collection
4
• Use the show tm-voq-stats dst_port all P command to display priority P counters for all the
ports in the system.
• Use the show tm-voq-stats dst_port all command to display aggregated counters for all the
ports in the system.
• Use the show tm-voq-stats dst_port all all command to display all priorities and aggregate
counters for all the ports in the system.
NOTE
The statistics are shown only when aggregated TM VOQ statistics collection is enabled.
Table 42 describes the columns displayed when using the show tm-voq-stats dst_port command.
Clearing the TM VOQ statistics
Use the clear tm-voq-stats dst_port command to clear all the counters for a specified port, or all
ports, when the statistics collection is enabled. This command also clears SNMP statistics reported
in brcdTMDestUcastQStatTable.
Brocade(config)# clear tm-voq-stats dst_port all
Syntax: clear tm-voq-stats dst_port [ ethernet slot/port| all ]
The slot/port variable specifies the slot and port number of the port group from which you want to
clear traffic manager statistics. The all option clears traffic manager statistics from all ports.
Displaying TM VOQ depth summary
The show tm-voq-stat max-queue-depth slot command provides summary of the maximum queue
depth of any queue from TM and provides additional information for debugging purposes. Knowing
the maximum queue depth also allows a way to set maximum queue size adjusted for the specific
traffic patterns on a system.
The following example displays summary of the maximum queue depth from the TM:
Brocade#show tm-voq-stat max-queue-depth slot
--------- Ports 3/1 - 3/24 ---------
QType Max Depth Max Util Destination Port
0 1013804 96% 3/1
1 1013848 96% 3/1
2 1013666 96% 3/4
3 1013794 96% 3/1
4 1013564 96% 3/1
5 538 0% 2/7
6 532 0% 2/7
