How to setup SPAN on 4900m Switch

[danmartinnorhrop]

Hey there,

I currently have IOS image cat4500e-entservices-mz.122-53.SG5.bin.  According to my research it appears SPAN is supported on this OS.  However, after looking at procedure notes using websites like here:

http://www.cisco.com/en/US/products/hw/switches/ps708/products_tech_note09186a008015c612.shtml#topic4 I cannot find and obviously not figure out how to use the SPAN  command.  My main objective is to simply setup a port mirror on one of my TenGigabitEthnet interfaces and from what I read SPAN is the best way to setup a tap interface on a cisco switch.  Any ideas or suggestions on how I can get SPAN to work or some other type of alternative I would be very grateful.

Thanks,

Dan Martin

Hi Dan,

You can use below commands.

config terminal

monitor session 1 source interface TenGig x/x  (This is port which you want to monitor)

monitor session 1 destination interface TenGig xx/xx (The port on switch packet capture software will be running)


You can verify the session with show monitor session 1 command.

Hope that helps.

Hey Najaf,

Thank you for your response.  I actually also found the correct answer in the cisco guide pdf for 4500 switches.  The links I originally looked at indicated to me there was an actual SPAN command but it looks like monitor is the command.  Anyhow, thanks again for your assistance.
