Chapter 4 Advanced Correlation Scenarios

Generic Routing Encapsulation (GRE) Tunnel Down/Up

Figure 4-16shows the Correlation tab of the Ticket Properties dialog box, which displays all the alarms that are correlated to the ticket, including the correlation for each GRE tunnel and its interface status.

Figure 4-16 Alarms Correlation to GRE Tunnel Down Ticket

As illustrated, the system provides the following report:

Root cause—Link down due to admin down

Correlated events:

GRE tunnel down ME-6524AGRE:Tunnel2 <-> ME-6524B GRE:Tunnel2

Interface status down ME-6524A IP:Tunnel2

Interface status down ME-6524B IP:Tunnel2

GRE tunnel down ME-6524AGRE:Tunnel3 <-> ME-6524B GRE:Tunnel3

Interface status down ME-6524A IP:Tunnel3

Interface status down ME-6524B IP:Tunnel3

etc.
