Stratix 5800 Port Mirroring
Summary
TLDRThis video tutorial demonstrates how to set up a SPAN (Switched Port Analyzer) port on a Stratica 5800 switch to mirror network traffic. It covers the process using both the command line interface and the web interface, with a focus on the latter. The video guides viewers through configuring a SPAN session on the web interface, selecting source and destination ports, and verifying traffic capture using Wireshark. It's a practical guide for network professionals to monitor and analyze network traffic effectively.
Takeaways
- 🔍 Span ports, also known as port mirroring, allow traffic from one port to be copied to another for analysis.
- 🌐 This feature is useful for capturing and analyzing network traffic, which can be sent to a network analyzer like Wireshark.
- 💻 The demonstration uses a Stratica 5800 switch, but the process is also applicable to the Stratica 5200 model.
- 🔌 The switch is configured for DHCP, with a default VLAN 1 and an IP address of 10.10.10.254.
- 🛠️ Two methods are available for creating a span session on Stratica switches: via command line interface or web interface.
- 🌐 The web interface is used in the video to create a span session, offering a user-friendly approach.
- 🔑 Users may encounter a warning about the switch's self-signed certificate, which can be bypassed by clicking 'advanced' and then 'continue'.
- 🔄 The process involves selecting a source port (in this case, Gigabit Ethernet 1/9) and a destination port (Gigabit Ethernet 1/3) for mirroring.
- ✅ After configuration, applying the changes and saving is crucial to ensure the span session is active.
- 📡 To verify the setup, traffic can be generated on the source port, and its reflection on the destination port can be observed using Wireshark.
- ❓ For further assistance or questions, viewers are directed to contact their local ESN account manager or automation specialist.
Q & A
What are SPAN ports used for?
-SPAN (Switched Port Analyzer) ports are used to mirror traffic from one or more source ports to a destination port, which can then be connected to a network analyzer for monitoring and analysis.
Can SPAN be set up for an entire VLAN?
-Yes, SPAN can be configured to mirror traffic from an entire VLAN that passes through the device.
What is the purpose of sending mirrored traffic to a network analyzer?
-Mirrored traffic sent to a network analyzer, such as Wireshark, allows for the capture and analysis of network traffic for troubleshooting, monitoring, and security purposes.
Which switch model is demonstrated in the video?
-The video demonstrates the setup process on a Stratica 5800 switch.
Is it possible to create a SPAN session on a Stratica 5200 switch?
-Yes, the process demonstrated can also be used on a Stratica 5200 switch.
What are the two methods to create a SPAN session on Stratica switches?
-You can create a SPAN session on Stratica switches either via the command line interface (CLI) or through the web interface.
What is the default VLAN on the demonstrated Stratica 5800 switch?
-The default VLAN on the demonstrated Stratica 5800 switch is VLAN 1.
What IP address is assigned to the default VLAN on the switch used in the video?
-The IP address assigned to the default VLAN on the switch is 10.10.10.254.
How can you access the web interface of the Stratica 5800 switch?
-You can access the web interface of the Stratica 5800 switch by opening a web browser and navigating to the IP address assigned to the switch.
What is the process to confirm if Wireshark is seeing the mirrored traffic?
-You can confirm if Wireshark is seeing the mirrored traffic by creating some traffic on the source port, then opening Wireshark and checking if the traffic is being captured and displayed.
Who should you contact if you need further assistance after setting up SPAN?
-If you need further assistance, you should reach out to your local ESN account manager or automation specialist.

🔍 Setting Up a SPAN Session on a Switch
This paragraph discusses the setup of SPAN (Switched Port Analyzer) ports on a network device, which are used to mirror traffic from one port to another for network analysis. The video demonstrates the process using a Stratica 5800 switch, which can be done via command line interface (CLI) or web interface. The video focuses on the web interface approach. The switch used in the demonstration is configured for DHCP, with a default VLAN 1 and an IP address of 10.10.10.254. The steps include logging into the switch's web interface, navigating to the configuration, setting up SPAN, selecting the source interface (Gigabit Ethernet 1/9), choosing the destination port (Gigabit Ethernet 1/3), applying the settings, and saving the configuration. The video also mentions using Wireshark on a PC to capture and analyze the mirrored traffic from the source port.

Highlights
SPAN ports, also known as Port Mirroring, allow traffic from one port to be mirrored to another.
SPAN ports can mirror traffic from an entire VLAN through a device.
The mirrored traffic can be sent to a network analyzer for analysis.
The video demonstrates setting up SPAN on a Stratica 5800 switch.
The process shown can also be applied to a Stratica 5200 switch.
Two methods for creating a SPAN session are available: command line interface and web interface.
The demonstration uses the web interface for creating a SPAN session.
The Stratica 5800 is set up for DHCP, with an IP address of 10.10.10.254.
Access the switch's IP address in a web browser to begin the configuration.
Users may encounter a self-signed certificate warning, which can be bypassed.
Log in to the switch using the credentials set during initial setup.
Navigate to the Configuration section and select SPAN to begin setup.
Choose the source interface to be mirrored, such as Gigabit Ethernet 1/9.
Select a destination port to receive the mirrored traffic, like Gigabit Ethernet 1/3.
Apply the configuration to the device and save the settings.
Connect a device to the source port to generate traffic for mirroring.
Use Wireshark on a PC to analyze the mirrored traffic from the source port.
Confirm that Wireshark is capturing the mirrored traffic from the source port.
The video concludes with a reminder to reach out for further assistance if needed.
Transcripts
span ports also referred to as Port
mirroring are ports on a switch or
router that can be set up to mirror
traffic on another Port ports are an
entire VLAN that pass through the device
and sends them back to a specific
destination Port where it can be sent to
a network analyzer in this video we'll
go through the process using a stratic
5800
[Music]
keep in mind this process can be used on
a Strax 5200 as well to capture the
output a network analyzer can be used in
this case we'll be using a PC with wire
shark installed there are two ways to
create a span session on the newest
generation of stratic switches you can
enable via command line interface or via
the web interface in this demonstration
we're going to go through the steps to
create a span using the web interface if
you need steps to use the command line
those instructions will be listed in the
description below the stratic 5800 we
are using as setup for dhtp so we are
connected via the ethernet port on my
laptop that has DHCP enabled for that
Port this switch only has one VLAN setup
which is the default VLAN 1 with an IP
address of
101010 254 so now you'll open your web
browser and go to that address you may
get a warning page about the switch's
self-signed certificate if so just click
on the advanced and then click continue
log in using the username and password
you set up when you initially set up the
switch on the left side you will click
on configuration then you're going to
click on span and then you'll click on
add this will bring up another window
where we will be able to choose the
source interfaces we will be mirroring
in this example we will scroll down here
to choose the interface gigabit Ethernet
1/9 then click the arrow to the right to
add it now go below and choose a
destination port in this example I'm
going to choose gigabit Ethernet 1/3 and
click the arrow to add click apply to
the device below and then click the save
icon in the upper right and then click
on okay now we can connect something on
Port 9 and create some traffic in this
case I'm using a second laptop now we
can confirm if wi shark is seeing the
traffic flow we are creating we do that
by opening wire shark and creating some
traffic on Port 9 by doing this we can
see that the traffic from Port 9 is
being captured and is mirrored to our
destination of Port 3 thanks for
watching and if you need further
assistance please reach out to your
local ESN account manager or automation
specialist
