ACCESS CONTROL LIST MANAGEMENT IN AN FCoE ENVIRONMENT
First Claim
1. A method, comprising:
- sending a deregister message through an Ethernet bridge to a Fibre Channel Forwarder (FCF) of a fabric in a Fibre Channel over Ethernet (FCoE) network, the deregister message including a MAC address of a virtual machine (VM) and instructing the FCF to temporarily suspend its fabric session with the VM.

Abstract
A Fibre Channel Forwarder (FCF) suspends a fabric session with a virtual machine (VM) in response to receipt of a deregister message from the virtual machine through an Ethernet bridge and transmits a deregister acceptance message to the VM. The Ethernet bridge detects the messages and updates its Access Control List (ACL) to remove the MAC address of the VM. While the fabric session is suspended, a virtual machine may migrate to another physical machine without terminating its connection to the fabric. After migration, the FCF resumes its fabric session with the VM in response to receipt of a register message from the VM through a second Ethernet bridge. The FCF responds to the register message with a register acceptance message. The Ethernet bridge detects the messages and updates its Access Control List (ACL) to add the MAC address of the VM.
