HI All
I am struck badly in bringing my L2 topology UP .
SW1 f19 ----------------------f13 SW4 f19 -------------------- f19 SW3
f21 ---------------------f15 f21 -------------------- f21
SW1 and SW3 should form a LACP dot1q trunk .
I guess all my configs are in place properly . But I am not abel to
bring up the trunk successfully .
I have done multiple shuts and no shuts .. Didnt helped
I get following error on SW4
Apr 20 19:20:14.563: %PM-4-ERR_DISABLE: l2ptguard error detected on
Fa1/0/13, putting Fa1/0/13 in err-disable state
