In addition to the generic information, the log shows an example of a gateway link failure:
[TR_MG board=01A0601v1 ip= 135.9.78.112 net_reg= 1 mg= 1 dest= 135.9.71.77 hop= 1 135.9.78.254 2.000ms 3.000ms 2.000ms]
Interpret the information as follows:
Brackets surround the failure-specific information
Type of IP event (TR-MG): a trace-route for a link failure to a gateway
Source board location (01v1)
Source IP address (135.9.78.112)
Network region number (1)
Media gateway number (1)
Destination IP address (135.9.71.77)
Hop number (1)
Hop IP address (135.9.78.254)
Three times in milliseconds (ms) for the three different attempts made at each hop along a route (2.000ms, 3.000ms, 2.000ms)
