- [Instructor] We've discussed SD-WAN implementation
in a previous module and talked about how Viptela
is the Cisco recommended solution for this
in conjunction with Cisco's DNA Center.
And that allows us to leverage automation
and virtualization capabilities.
As a brief overview of the SD-WAN planes of operation,
we can break this down into four planes.
The Data Plane, the Control Plane,
and the Management Plane,
which you're probably familiar with
from traditional networking models,
and the fourth plane, known as the Orchestration Plane.
There are four different solutions
within Cisco's SD-WAN architecture created
to manage each of those four planes,
as we've already outlined in our SD-WAN module.
In here we want to look specifically at an overview
of Cisco's vManage,
vManage is the graphical interface
for managing the SD-WAN solution.
This is where you would perform configuration,
monitoring, provisioning, and trouble-shooting.
Here I'm logged in to the DevNet Sandbox environment
for Cisco vManage.
You can see at the main dashboard
we have the four relevant pieces of the architecture.
We have vSmart, which resides within the control plane,
and we think of that as the brain of the SD-WAN solution.
As policies are created, the vSmart component
is responsible for the enforcement of these policies.
We have the edge devices themselves called WAN Edge here,
or vEdge routers in other words.
We have vBond, which is responsible for provisioning.
And of course we have vManage,
which is where we perform
configuration monitoring and troubleshooting.
If we take a look at the WAN Edge section,
and we click on this so we can currently see
we have one device listed as down.
Actually that just changed.
We have two devices listed as down,
two devices listed as in the up state.
Let's click on that,
and that will show us, in this case,
as list of the vEdge routers that we have
in the up state in this lab environment.
We can see the reachability status,
we see the System IP address and so on.
And if we check out our options over here,
on the right-hand side you can see that we have
an option for Real Time,
we have an option for the Device Dashboard,
and we have another third option
that's actually missing here.
That is the ability to SSH into the terminal
for manual configuration.
So in addition to Real Time monitoring
and the Device Dashboard, we would normally have
the ability to SSH to the device.
This being a Cisco DevNet lab, of course,
that's not possible.
We also have sub-menus available on the left
if we exit out of our WAN Edge section.
Over here on the left-hand side, we have some sub-menus
for monitoring is up top and Device Configuration.
We have Tools, Maintenance, Administration, and vAnalytics.
Let's click on the Monitor tab.
And we'll choose the network option from there.
And again we see a list of devices
that are in our network.
Not just he WAN Edge, not just those vEdge routers,
but everything is listed here.
And from here, if we click on a device,
let's just choose one of these vEdge routers.
We're going to be brought to a device overview screen.
And from here we can see a really nice looking dashboard.
We can see crash reports.
We can see temperature sensors.
We can reboot the device from here.
We can look at our CPU and memory usage.
Lots of great information for monitoring our network.
And once we're here,
we can dig even deeper
with the menus on the left.
We can see application-specific data
under the applications tab near the top.
So if we wanted to see data about
certain applications that were running,
if we wanted to see interface information
about the throughput and which interface are up and down.
We can check out the TCP Optimization option,
the WAN Throughput.
We can look at specific flows.
We can look at lots of things.
Lots of these features you would find in a program
such as PRTG, which is a network monitoring program
that helps troubleshoot bandwidth problems.
We see a lot of those same features.
We see the ability to look at flows.
We can have a top talkers list
which tells us those devices
that are communicating the most within our network
and many, many more options found throughout
these device menus.
If we go to the bottom left
and choose the Real Time option,
it looks as though this device
has actually just gone offline,
so let me select a different device.
There we go.
If we choose the Real Time option on the left
that it's going to show us some Real Time stats.
Real Time information reports regarding this device.
If we click in the device options at the top,
you'll see that we can do lots and lots of things.
So just for example,
let's say ARP table,
if we choose ARP table
and we'll choose these show filters option,
this is going to show us a real time view
of the ARP table that's running on this device.
And the same with any other metric
that we choose in these device options.
If we say for example,
let's say interface, interface detail,
and again that's going to show a list
of all of the interface states on this router,
whether they're up or whether they're down.
So really great information to have here.
If we choose control connections on the left,
we'll see a single instance of vSmart here,
which is controlling this device.
So that's exactly what we would expect to see
in this topology.
We can go under the WAN menu
and we can choose one of those sub options.
We can see tunnel endpoints using IPsec.
We can also see jitter loss and latency metrics
gathered by the manage.
We can go under troubleshooting,
if we choose that
and we can troubleshoot a specific devices connectivity,
for example, we could ping that device.
We have the option to trace route as well.
We can see the overall traffic health
and perform troubleshooting on our tunnels
on specific applications,
or we can even simulate traffic flows
when we're troubleshooting.
So again, this is just an overview
of the interface and the menus,
but as you can see, Cisco vManage
has lots of features packed in
that make it a really thorough tool for SD-WAN management.
