I think this MAC isn't assigned to some equipment, this is a problem in Cisco Switches, if this your case then try this:
Configure your cisco switches if it's has IOS software apply mac-address-table static 0000.0000.fe00 FastEthernet0/x vlan y check in terminal monitor for the FastEthernet number and vlan of this, if you see two ports that learn this MAC select only one. same for 0000.0000.fe01 -----Mensaje original----- De: Mailing list for discussion of Firewall-1 [mailto:[EMAIL PROTECTED] nombre de Burton, Chris Enviado el: Jueves, 05 de Agosto de 2004 11:57 a.m. Para: [EMAIL PROTECTED] Asunto: Re: [FW-1] virtual mac address I had to make this change for the same reason you described in your email and I have seen no problems with this (NG FP3 Cluster), although Checkpoint does recommend that you place each cluster into a separate VLAN or switch/hub for the synchronization network, thereby eliminating the need for the "magic" number change.

However, this is the same for both clusters and it causes the cisco switches to spot the same mac on different ports and complain, and possibly misdirect traffic, so I'd like to fix it. I'm going to change the fwha_mac_magic parameter to 00xfc on one cluster pair, but was curious if anyone else had done so. thanks, ian Ian Brown Senior Network Analyst OAG Worldwide Church Street Dunstable Bedfordshire United Kingdom LU5 4HB [EMAIL PROTECTED] Some worlds collide, others rarely meet ================================================= To set vacation, Out-Of-Office, or away messages, send an email to [EMAIL PROTECTED] in the BODY of the email add: set fw-1-mailinglist nomail ================================================= To unsubscribe from this mailing list, please see the instructions at http://www.checkpoint.com/services/mailing.html ================================================= If you have any questions on how to change your subscription options, email [EMAIL PROTECTED] ================================================= ================================================= To set vacation, Out-Of-Office, or away messages, send an email to [EMAIL PROTECTED] in the BODY of the email add: set fw-1-mailinglist nomail ================================================= To unsubscribe from this mailing list, please see the instructions at http://www.checkpoint.com/services/mailing.html ================================================= If you have any questions on how to change your subscription options, email [EMAIL PROTECTED] ================================================= ================================================= To set vacation, Out-Of-Office, or away messages, send an email to [EMAIL PROTECTED] in the BODY of the email add: set fw-1-mailinglist nomail ================================================= To unsubscribe from this mailing list, please see the instructions at http://www.checkpoint.com/services/mailing.html ================================================= If you have any questions on how to change your subscription options, email [EMAIL PROTECTED] =================================================
