The following examples illustrate failed hops along the route:

[TR_IPSI board=PROCR ip= 172.28.224.18 net_reg= 1 
ipsi= 2 dest= 172.28.224.2 hop= 1  172.28.224.18 
2965.401ms !H  2997.313ms !H  3000.750ms !H]
[TR_IPSI board=PROCR ip= 172.28.224.18 net_reg= 1 
ipsi= 1 dest= 172.28.224.1 hop= 1  * * *]
[TR_IPSI board=PROCR ip= 172.28.224.18 net_reg= 1
ipsi= 1 dest= 172.28.224.1 hop= 2  * * *]
[TR_IPSI board=PROCR ip= 172.28.224.18 net_reg= 1 
ipsi= 1 dest= 172.28.224.1 hop= 3  * * *]

The example shows the case for a media module failure; other failures would be analogous. Depending on the circumstances, sometimes very long times are shown along with error codes, if known. In other circumstances, the times are shows as “*.”
