quick RSPAN question

monitor session 2 destination remote vlan 500 reflector-port f0/x

 

 

on the 3550 you need to enter in a reflector-port in the monitor session cmd. You dont need this pon the 3560s...

 

what is this reflector port??...i did a quick read http://www.cisco.com/en/US/products/hw/switches/ps708/products_tech_note09186a008015c612.shtml#char_reflect

and i cant seem to set any port to loopback as i can on a router...i tried the no switchport and then loopback cmd...didn't work...i sorta get it...

 

any clarification appreciated

 

thanx

  • actually a better question would be.....if i understand what a reflector port is doing...why dont i need one on the 3560?

  • Hi ToxicAvenginator,

    You will find your answer in this TCP Mag article written by the great Scott Morris :)

    Basically, 3550 uses "Reflector Port" because of its H/W limitation.

  • Hi ToxicAvengnator,

    For CCIE RS lab don't worry much about 3550 since they're not listed in the current blueprint, instead chech RSPAN in 3560 which the implementation is much easier. But for other purpose its perfectly fine to know it.

    part of why i'm studying for my CCIE is cause i'm curious about stuff....sometimes to an anal and annoying degree...(which admittedly sometimes wastes time...like right now...but i'm on break)..

    now if i take the curiosity away....so goes my desire to be a CCIE (its not all about the $)...

    so..its a catch 22...[:(]

  • I worry that I am addicted to studying for CCIEs. LOL

  • i cant say that....i cant wait to get this over with...maybe i'll look back on it when its done and think it ws fun but right now...i dont like having this constant hollow feeling in the pit of my stomach...

  • Perfectly normal and you're right.
