Verifying Traffic

Here, we want to verify that the tunnels are carrying traffic and that flows are being optimized.

w	To verify tunnel status

From the menu, select Configuration > Tunnels. The Status column indicates whether the tunnels are up.

w	To view tunnel statistics

From the menu, select Monitoring > Tunnels. This tab displays the statistics associated with each tunnel.

w	To view flow optimization

From the menu, select Monitoring > Current Flows.

w	To verify the Cisco SLA

With the first two commands, the router pings the Silver Peak appliance to see if the latter is up. If the appliance is down, the router stops forwarding traffic to the appliance and relies instead on its own routing tables.

1	Show ip sla summary

•	when tracked appliance is down

•	when tracked appliance is up

2	Show track brief

•	when appliance is down

•	when appliance is up

3	Show route-map all

If the bytes and packets are not incrementing, then the route policy and access list are not matching the traffic that you want to redirect. If that’s the case, check the IP addresses you entered, as well as the route policy.

w	To verify connectivity for pass-through traffic

As a best practice, always verify connectivity for all devices in the network. For example, if you’ve configured a route policy to cause certain traffic from certain devices to be handled as pass-through or pass-through unshaped, you should also verify connectivity for these devices.

w	To verify network connectivity

Test network connectivity by using your applications. For example, do a CIFS mount or an FTP transfer.
