Re: L2 Trunk question

knuckleheadbob · ‎10-18-2017

working with 3845 w 2 nm-16esw-1g network modules having issues with connectivity across the trunks i have also duplicated the issue with gns3 so i must be missing something simple, if anyone could shed some light on what im missing. for reference here is my gns3 config just trying to do a simple ping from R1-R2 / R2-R1 on any vlan

Hi,

Could you share the output of "sh int status | i Fa1/0", "sh int fa1/0" and "sh spanning-tree"from both devices?
