Re: [Bridge] Error in Bridge Settings!!

Etienne:   Your response makes sense. In my case, if I enter the script manually, the message goes away. That’s why your response makes sense. Since the process works, I am going to leave it to that.   Thanks.   Kirti   -----Original Message----- From: Etienne Pretorius [mailto:[EMAIL PROTECTED] Sent: Thursday, June 29, 2006 2:35 AM To: Kirti S. Bajwa; bridge@lists.osdl.org Subject: Re: [Bridge] Error in Bridge Settings!!   Let me first explain that I have the same problem in my Ethernet bridge setup. What I have determined, that there is a loop in my network but STP is preventing a packet broacast storm. I have switches instead of hubs but my primary bridge is broadcasting packets somehow, because when I unplug the primary's Ethernet from our internal network then those messages stop appearing. I am in the process of re-setting up that bridge so that *hopefully* I wont be seeing this message in future. I wander if it might be the HUBs you using.... they might be broadcasting any packet to all ports and so your bridge will receive its own packets back to it? Like I said - I have the same problem, but the setup still works and I am trying to remove loops in my network to see if that *really* is the cause to the error message. Kind Regards Etienne Kirti S.
