not too sure if i agree with assigning it to the native vlan. i would have been more incline to set it on the vlan it belongs. when you do a show cam dyn|perm|static|system the vlanid is one of the attributes shown - like a unique vlan:mac key pair (although mac addresses do not have to be unique).
setting the perm entry to the native vlan would mean to me that mac is only vis on that vlan. hence i would say set the perm entry to the vlan the destination it is on. since a trunk is a trunk is a trunk. i would have applied the same reasoning to an accessport. if the mac needs to have vis across more than 1 vlan, i would add it to each vlan required. hth, Mark. -----Original Message----- From: steve [mailto:[EMAIL PROTECTED]] Sent: Monday, January 06, 2003 11:47 AM To: [EMAIL PROTECTED] Subject: Re: set cam permanent HELP! [7:60448] hey miss P if you do a show trunk it should show you it`s native vlan ....that is the one you are after ... "from CCO" The following example shows how to add a unicast entry to the table for module 2, port 9, and how to add a permanent multicast entry to the table for module 1, port 1, and module 2, ports 1, 3, and 8 through 12: Console> (enable) set cam static 00-00-0c-a0-03-fa 2/9 Static unicast entry added to CAM table. Console> (enable) set cam permanent 01-40-0b-a0-03-fa 1/1,2/1,2/3,2/8-12 Permanent multicast entry added to CAM table. Console> (enable) i got the above from http://cco-rtp-1.cisco.com/en/US/products/hw/switches/ps679 /products_command_reference_chapter09186a008007f2dc.html#13648 watch the wrap.... from memory if you specify the native vlan and ONE port in the trunk that SHOULD include all ports of the trunk with the set cam command....I just can`t be 100 % HTIOSH (hope this is of Some help) Steve --- Original Message ----- From: "Priscilla Oppenheimer" To: Sent: Monday, January 06, 2003 6:37 PM Subject: set cam permanent HELP!
