Re: How to disable MAC learning on SPAN port on Cat 3550

I hope it's not possible with these 3550 switches. Because for this switch, SPAN configured through monitor session command and it's not having any option to disable learning. But as far as I know, for IOS switches like 3550, LEARNING is DISABLED by default. If you go to set based switches like Cat 4000 series there you can find like "set span 1/1 1/3 both inpkts enable learning disable create" to disable MAC address learning.
