learning cisco was initially very difficult until I came across this guy call Jeremy. Thank you Jeremy for the tutorials. It wsa boring watching you. Stay bless for ever.
Jeremy, you are truly a one man show. It is inspiring to watch you doing what seems to be "magic". You have a gift. Thank you for hours of knowledge and fun!
My first post ever... You are the ultimate nerd! Thanks for the video, I've never done RSPAN. Things are so much easier when you get a crash-course! Much appreciated, sir.
Great video!! I needed a quick refresh and this was the perfect video. I need to run off and span some ports and couldn't remember if the RSPAN would knock off some ports, thank you!! I will stick to spanning the ports, only 7 switches. =)
This Was one best micro-nugget , And You know Jeremy, the best information we got not only SPAN and RSPAN but also about Twinkies .. but Twinkies are not good for health of Networkers
Hi- I have 66 SPAN sessions, I have a monitor running on one of my switch interfaces. I want to monitor all traffic that comes in and out the switch( even to all vlans). is there a command to have all ports as the source of monitor or do I have to use each SPAN session per vlan?
with rspan your source switch used session #1 and your destination switch used #2? is each session independent from switch to switch or should they match?
I configured RSPAN in order to monitor an interface from our firewall, which is connected to a routed interface in a core switch. Everything went fine until the time where the sniffer started to capture traffic: it only reflects broadcast traffic. The same scenario repeats when I configure RSPAN to monitor a proxy interface (this interface is not a routed one) Using tcpdump I can capture traffic and obtain a .pcap file... Can you help me?
I live in the UK. Just whatched the video. way way way fast but i whatched it multiple times!!!!!!!!!! ive setup local SPAN on a 2950 switch - Successfully I added another switch 2950 & TRUNKED it to the other switch adding vlan 999 as per video in trunk mode on both ends i also added vlan 999 on both host pc ports THE VIDEO STATES that there maybe a specific port used for RSPAN - can anyone tell me which port as I assume i CANNOT use any port for RSPAN according the the video ????
Thank you for your question, Aurelien! RSPAN sessions can work with a maximum of five SPAN sessions. Some switches will have different limitations. You should be able to assign more than one vlan to be monitored. There are some guidelines however that will need to be met in order to make sure it works. www.cisco.com/c/en/us/td/docs/switches/lan/catalyst4000/8-2glx/configuration/guide/span.html#wp1021764 We hope this helps! Thank you for learning with us.
I have a question. If we configure a SPAN monitoring, how should we configure the destination port. Does it have to have any configuration or it just has to be no shut?
i don't know if you answer my question sense this movie is old or maybe somebody else see this comments can answer me one thing i don't get it: if there are no VLAN it all in the switch like new switch why i can't listening to all other traffic in the the network/ports this video explain how to listening to traffic assuming that all other port that i want to listening are attech to VLAN?

I absolutely love this Jeremy, he made my Cisco career fun.

This was informative for me, and I'd like to thank you for presenting :)
I wrote Jeremy an email about this subject quite a long time ago and am happy to see an answer! TYVM, sir!
I've never laughed so good at the end there... wow the dynamic of your personality is AMAZING !!!
My first post ever... You are the ultimate nerd!

The ending...Hahaha. Really Jeremy??? Thanks for the video.
Dust off the cobwebs from the weekend with Jeremy Cioara's newest MicroNugget! Jeremy explains how to configure SPAN and RSPAN on a Cisco switch here:
Hahaha Twinkies. You might find that on e-bay. Very good video. Thank you!!!
Don't you just love Jeremy? He makes networking seem so easy!!!
Thank you Jeremy, needed to do this half a year ago, figured it out through the internet but its a nice refresher.
Great video!! I needed a quick refresh and this was the perfect video. I need to run off and span some ports and couldn't remember if the RSPAN would knock off some ports, thank you!! I will stick to spanning the ports, only 7 switches. =)
This Was one best micro-nugget , And You know Jeremy, the best information we got not only SPAN and RSPAN but also about Twinkies .. but Twinkies are not good for health of Networkers
super easy, ot the point without missing any important information (uncluding reflector port) and funny :) got my like
Thank you so much for this video!!! 🙏🏽🙏🏽🙏🏽
Hi- I have 66 SPAN sessions, I have a monitor running on one of my switch interfaces. I want to monitor all traffic that comes in and out the switch( even to all vlans). is there a command to have all ports as the source of monitor or do I have to use each SPAN session per vlan?
Epic Twinkies!!!! Dont you ever quit Jeremy......
That made me smile! Thank you!
great video. cbt nuggets are the best.
Awesome explaination!
Thanks very much for your sharing Jeremy, does RSPAN works if traffic passing through the router?
I'd love to see a MicroNugget on configuring ERSPAN, where to use it and where not to use it. Thanks
Brian, thanks for the feedback! You can make a formal MicroNugget request here: cbt.gg/1axFtY4
Thanks for the Great video
hi sir, port 47-48 are trunked going to our firewall, if i monitor that trunk then i can monitor all vlan at is allowed to pass on that vlan?
with rspan your source switch used session #1 and your destination switch used #2? is each session independent from switch to switch or should they match?
I configured RSPAN in order to monitor an interface from our firewall, which is connected to a routed interface in a core switch.

Can you help me?
Oh i miss Jeremy!
That is legendery
Thank you Jeremy your the best :D
I live in the UK. Just whatched the video. way way way fast but i whatched it multiple times!!!!!!!!!!
ive setup local SPAN on a 2950 switch - Successfully
I added another switch 2950 & TRUNKED it to the other switch adding vlan 999 as per video in trunk mode on both ends
i also added vlan 999 on both host pc ports
THE VIDEO STATES that there maybe a specific port used for RSPAN - can anyone tell me which port as I assume i CANNOT use any port for RSPAN according the the video ????
Thank u Jeremy :)
thx very helpful video :)
possible with rspan to monitore 2 different vlans? Thanks
Thank you for your question, Aurelien!

at the end ,,,, funny !
I have a question. If we configure a SPAN monitoring, how should we configure the destination port. Does it have to have any configuration or it just has to be no shut?
i don't know if you answer my question
sense this movie is old or maybe somebody else see this comments can answer me
one thing i don't get it: if there are no VLAN it all in the switch like new switch
why i can't listening to all other traffic in the the network/ports
this video explain how to listening to traffic assuming that all other port that i want to listening are attech to VLAN?
Dear Jeremy i have done the lab but all my traffic on that port stoped working no internet no net connection all gone to zero may i know why ??
What happens if my traffic is using QinQ?
Still am I able to filter by inner/outer tags using the RSPAN?
thank you :)
Great video, but font size too small.
Thanks again.
Choose HD display from video settings. full screen .. you will be happy :)
u fucking genius!!! hahaha, love it
Network genius..
from which series is this ?
R.I.P twinkies :(
We sit in our chairs!
very small the terminal screen
Speaks very fast..!!
For a foreigner like me, its difficult to catch the words..
Any way nice information,,thanks!!!!
You can change its speed... but this guy sounds drunk that way lol
Sir why you are so fast?
don't cry. The mainstream media says Twinkies might be back by June.
HAHAHA what a legend
Why do you think hostess went out of the business?! Look at wiki they're up and live again....
Talks far too fast !!!
i thought the speed was perfect, most people explain concepts at groan inducing slow speeds.
