Introduction:

In Spectrum, we use the term "live link" or "live pipe" to signify a link between 2 devices that has active link monitoring enabled.

This is disabled by default as it may not required by some users and may have a negative performance cost on the system.

 

 

Question:

What attributes do we need to enable, to turn on link monitoring?

Environment:
All supported Spectrum environments.
Answer:

To enable Live pipes or live links, please set the attributes below as follows:

To set this on on all interfaces at once, we can use policy manager. 

 

1. Generate Alarm on Port is controlled by the attribute GeneratePortStatusAlarms at the port level.

2. Generate Alarm on Device is controlled by the attribute AssertLinkDownAlarm at the port level.

3. I have verified from my lab server that the default behaviour of the alarms is as follows:

 

Generate Alarm on Port   (default is yes).

Generate Alarm on Device (default is no).

 

PollPortStatus (0x1280a) - Controls status polling of a port whose connectivity is not modelled.

Valid values are TRUE or FALSE.

 

ok_to_poll (0x11dd8) - Used to make the pipe associated with this port "live".  The status of the port will be polled.

Valid values are TRUE or FALSE.

 

AlarmOnLinkDownTrap (0x11fc2) - Determines how SPECTRUM handles a Link Down trap on this particular

port (0 for ignore the trap, 1 for process the trap).

AssertLinkDownAlarm (0x12957) - Determines if SPECTRUM should generate a yellow alarm on the device

model when a link down trap is received for this port.

Valid values are TRUE or FALSE.

 

GeneratePortStatusAlarms (0x12a54) - Used to tell SPECTRUM that a port status alarm should never be generated on this port.

Valid values are TRUE or FALSE.
