Putting your appliance online in a production network requires special attention to prevent disruption or confusion, especially in a complex environment
Use the SD-WAN
4000/5000Use the SD-WAN
4000/5000 GUI to monitor traffic after you configure a LAN link and a WAN link. SD-WAN
4000/5000 allows a very simple link definition.
- Configuring the Links
- To enable monitoring, you must first configure one LAN link and
one WAN link. To do so, edit the default links on the Configure:
Links page as follows:
- Edit one link so its name
is "LAN," its type is "LAN," and its speed is 10 Gbps in both
directions. Delete its existing filter rule, then click Add Rule, and then click Save to
save a link definition that matches all traffic.
- Edit the other link so that its
name is "WAN," its type is "WAN," its speed is 95% of the aggregate
speed of your site's WAN links in each direction. Delete its
existing filter rule, then click Add Rule, and
then click Save to save a link definition that
matches all traffic.
To verify that link configuration is working
correctly, traffic must be flowing. If the network does not have
enough traffic to fill the WAN link to capacity, run test traffic
to fill the network to capacity. Then look at the link reports on
the Reports: Link Usage tab. The following figure
shows these reports.
- General Monitoring
- If WCCP is configured, verify that the service groups are in operation and the routers are redirecting traffic. (Note that the SD-WAN WCCP page packet counts are not present in SD-WAN
4000/5000. Check traffic by other means, such as on the Monitoring: Active Connections page, and on the router.)
- On the remote SD-WANs, verify that outgoing connections are being accelerated, and that all accelerated connections to the datacenter report the same Partner Unit on the remote appliance's Monitoring: Connections page. When load-balancing is working properly, all outgoing accelerated connections show the same Partner Unit. (However, incoming accelerated connections might show different units.)
- Double-check remote SD-WANs for correctly set bandwidth limits, to prevent remote issues from being misidentified as datacenter issues.
- Generally monitor the SD-WAN
4000/5000 unit for alerts.
- In the broker UI, use the Dashboard, the Monitoring: Remote Partners, and perhaps the Monitoring: Appliance Load pages to monitor the overall activity and load of the system.
