Spirent TestCenter: Where do I find link status events on test ports?
Environment/Versions
The port or All Ports link status indicator LED can be red, amber, gray, or green.
A port that is in loopback mode is indicated by a green arrow that looks to be pointing back to its tail.
Red indicates a link fault occurred on the port.
Amber indicates link on the port was broken by the user via the Break Link toolbar button or the L2Test: Break Link command in the Command Sequencer (L2TestBreakLinkCommand in Tcl).
Gray indicates the link is down.
Green indicates the link on the port is up.
The All Ports link status LED indicates project level port link status. If any port is down, the LED is red.
Answer
The bll.log file will show the link up/down events.
Prior to 4.90
You can search for these phyStatuses.
phyStatus(0)
= gray, link is down
phyStatus(1)
= green, good link
phyStatus(2)
= red, link fault
4.90 and later the phyStatus changed to more readable format as shown below.
link status changed to Down (local fault)
= gray
seen with ports that has no transceiver
if an SFP fiber port, could be see with fiber disconnected or laser off
link status changed to Up
= green
link status changed to Error (local fault)
= red
transceiver installed but cannot get link
if an SFP fiber port, this is with fiber connected and laser on
different from link down status (gray)
link status changed to Admin Down (local fault)
= amber
seen on the port that initiated a break link
