-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Daniel Cotts Sent: Tuesday, February 19, 2002 7:13 PM To: [EMAIL PROTECTED] Subject: RE: Hold1 , timers versus time [7:35910] "Cisco LAN Switching" by Clark & Hamilton p218 "The Spanning-Tree Protocol also uses a seperate Hold Time value to prevent excessive BPDU traffic. The Hold Time determines the minimum time between the sending of any two back-to-back Configuration BPDUs on a given port. It prevents a cascade effect of where BPDUs spawn more and more other BPDUs. This parameter is fixed at a non-configurable value of one second." I have quoted this book many times on this list. Hint - buy it! Your output seems to be from a 2900XL series switch: http://www.cisco.com/univercd/cc/td/doc/product/lan/c2900xl/29_35wc/cr/clicm ds.htm#xtocid21946105 shows similar output without really explaining it. For more detailed explanations see: http://www.cisco.com/univercd/cc/td/doc/product/lan/cat5000/rel_5_2/cmd_ref/ sh_sp_te.htm#21020 and check out the "show spantree statistics" area. > -----Original Message----- > From: Pierre-Alex GUANEL [mailto:[EMAIL PROTECTED]] > Sent: Tuesday, February 19, 2002 5:34 PM > To: [EMAIL PROTECTED] > Subject: RE: Hold1 , timers versus time [7:35910] > > > Resent > > -----Original Message----- > From: Pierre-Alex GUANEL [mailto:[EMAIL PROTECTED]] > Sent: Tuesday, February 19, 2002 4:51 PM > To: Cisco > Subject: Hold1 , timers versus time > > > > > Can someone please explain me what the "hold" timer is and what the > difference between "times" and "timers" is? > > I can't find documentation on this.
