Introduction

Pica-OVS mode switch needs to store some basic switch information and some run-time information in the inventory database, this feature is running when Pica-OVS starts.

There are five kinds of information in this module as shown below, including basic Switch Information, SFP/QSFP Information, Counter Information, Alarm Information, and Hardware Flow Information.

Switch Information

Show function control information.

root@PicOS-OVS$ovs-invctl show  
23aa0580-9578-471a-abae-a9c84b73affd
  sfp_enable: true
  sfp_query_interval: 10
  counter_enable: false
  hwflow_enable: false
  counter_query_interval: 30
  hwflow_query_interval: 30
  alarm_enable: false
  alarm_high_temp: 176
  alarm_low_temp: 32
  last_alarm_id: 0

 

Show basic switch information in the Switch Inventory table, including switch information, temperature information, port information and SFP/QSFP information.

Before checking the switch information, the DUT must create a bridge and add ports into the bridge. Then make sfp enable-true.

SFP/QSFP Information

SFP/QSFP information is stored into the database if user enables this feature. The Administrator could enable/disable this function by using command "ovs-invctl enable-sfp {true | false}".

root@PicOS-OVS$ovs-invctl enable-sfp true
 
Administrator could show these information by command "ovs-invctl show-switch-inventory" or "ovs-invctl show-sfp-qsfp".

Administrator could control the refresh interval by command "ovs-invctl set-sfp-interval."

root@PicOS-OVS$ovs-invctl set-sfp-interval 50
root@PicOS-OVS$ovs-invctl show
23aa0580-9578-471a-abae-a9c84b73affd

 counter_query_interval: 30
 hwflow_query_interval: 30
 alarm_enable: false
 alarm_high_temp: 176
 alarm_low_temp: 32
 last_alarm_id: 0

Counter Information

There are 4 types of counters: flow, group, meter, and port counter. As expected, the flow counter is the counter of each flow and the port counter is the counter of each port. The meter counter is the counter of each meter, associated with the band counter, and the group counter is the counter of each group, associated with the bucket counter.

Note: this kind of information generates a lot of data. Turning this on will spend some CPU and memory. So if this information is not needed, please turn it off.

 

Administrator could enable/disable this function by command "ovs-invctl enable-counter {true | false}"

root@PicOS-OVS$ovs-invctl enable-counter true

 

Administrator could control the refresh interval by command "ovs-invctl set-counter-interval".

root@PicOS-OVS$ovs-invctl enable-counter true
root@PicOS-OVS$ovs-invctl show

Alarm Information

Alarm stores the alarm information about: PSU, FAN, OPTICS, PORT, TEMP, MANAGEMENT_PORT_STATUE. This information is stored in the Alarm table.

Administrator could enable/disable this function by command "ovs-invctl enable-alarm {true | false}".

root@PicOS-OVS$ovs-invctl enable-alarm true
 
root@PicOS-OVS$ovs-invctl show
23aa0580-9578-471a-abae-a9c84b73affd
  sfp_enable: true
  sfp_query_interval: 50
  counter_enable: true
  hwflow_enable: false
  counter_query_interval: 20
  hwflow_query_interval: 30
  alarm_enable: true
  alarm_high_temp: 176
  alarm_low_temp: 32
  last_alarm_id: 9


The Administrator could control the temperature threshold by the command "ovs-invctl set-high/low-temp". When the switch temp id is higher or lower then the temperature threshold, it will produce an alarm message.

root@PicOS-OVS$ovs-invctl set-low-temp 10
root@PicOS-OVS$ovs-invctl set-high-temp 133
 
root@PicOS-OVS$ovs-invctl show

  sfp_enable: true
  sfp_query_interval: 50
  counter_enable: true
  hwflow_enable: false
  counter_query_interval: 20
  hwflow_query_interval: 30
  alarm_enable: true
  alarm_high_temp: 133
  alarm_low_temp: 10
  last_alarm_id: 9


The Administrator could show this information by the command "ovs-invctl show-alarm"

root@PicOS-OVS$ovs-invctl show-alarm

  switch_name: PicOS-OVS
  entity_text: "PSU 1"
  text: "PSU removed"
  time: "Tue Nov  3 13:49:39 2015"

Hardware Flow Information


Note: This kind of information is very large, turning this feature on will spend some CPU and memory. So if this information is not needed, please turn it off. For saving memory, we support max 20,000 hardware flows written into the database. If the count of hardware flows is exceeded, they are discarded.

 

Administrator could enable/disable this function by the command "ovs-invctl enable-hwflow {true | false}".

root@PicOS-OVS$ovs-invctl enable-hwflow true
 
root@PicOS-OVS$ovs-invctl show

  hwflow_query_interval: 30
  alarm_enable: true
  alarm_high_temp: 133
  alarm_low_temp: 10
  last_alarm_id: 9

 

The Administrator could control the refresh interval by command "ovs-invctl set-hwflow-interval INTEGER".

root@PicOS-OVS$ovs-invctl enable-hwflow true
 
root@PicOS-OVS$ovs-invctl set-hwflow-interval 50
root@PicOS-OVS$ovs-invctl show
