David- it's been a while since I did this, but from what I understand you to say, you are trying to provide fault tolerance (fail-over) at the NIC level for these servers.
I can't vouch for the 6500s, but on the 5500s that I used to manage, we used Intel NICs in a "teaming" fashion (which was to provide said fault tolerance). These NICs had their FastEthernet cables going to each switch respectively. (4 NICs in each Server, 2 CAT5500's to plug into). The virtual mac's of the Teaming group was plugged into the port security table on the CATs. The CATs were also Trunk'd together via GBICs, so STP would block one Fast-Ether-Channel group of NIC cables on one switch while allowing the other group to operate. So, the short of it is, I believe you'll have to set up an EtherChannel with the NIC Pool(s) and it's assumed that you already are Trunking between your 6500's for backbone redundancy. Port Security should be straight forward- just one Virtual-MAC per NIC Pool to be plugged into the MAC Security Table, and reference the security mac table on the ports you want to enable port security. It's been a couple of years since I did this, so hopefully I remembered all the steps required. YMMV :) HTHs -Mark -----Original Message----- From: David Vital [mailto:[EMAIL PROTECTED] Sent: Monday, June 02, 2003 6:59 PM To: [EMAIL PROTECTED] Subject: Virtual MAC and Port Security [7:70030] I have several Servers that are going to be doing NIC pooling. So I'm supposed to see a virtual MAC address instead of the actual physical address of the NIC's. I run the NICs from one server to different switches for fault tolerance. If I have several 6500 series switches how can I set it up for Port Security? I know I can set up the ports to handle several MAC's but if they are running the same virtual MAC what's the answer?
