Port profile management for virtual cluster switching
View Patent ↗One embodiment of the present invention provides a switch system. The switch includes a port profile which specifies a set of port configuration information. During operation, a control mechanism within the switch detects a source MAC address of an incoming frame and determines that the MAC address is associated with the port profile. The control mechanism then applies the port profile to a switch port on which the frame is received.
1. A switch, comprising:
a storage device storing:
a port profile data structure specifying a set of port configuration corresponding to a plurality of media access control (MAC) addresses; and
a second data structure mapping a respective MAC address of the plurality of MAC addresses and a corresponding virtual local area network (VLAN) identifier to a same policy group identifier; and
a control module configured to:
determine that:
a frame's source MAC address is associated with the port profile data structure; and
the frames source MAC address is in the plurality of MAC addresses mapped to the policy group identifier; and
in response to the determination, apply the port profile data structure to an ingress switch port of the frame, wherein applying the port profile data structure sets the port configuration specified in the port profile to the ingress switch port.
2. The switch of claim 1 , further comprising a fabric switch management module configured to operate the switch as a member switch of a fabric switch, wherein the fabric switch comprises one or more physical switches;
wherein the storage device stores the port profile data structure in response to the switch being a member switch of the fabric switch.
3. The switch of claim 1 , wherein the control module is further configured to, in response to the determination, apply the port profile data structure to an egress switch port of the frame, wherein applying the port profile data structure sets the port configuration specified in the port profile to the egress switch port.
4. The switch of claim 1 , wherein the frame's source MAC address is a MAC address of a virtual machine.
5. The switch of claim 1 , wherein the set of port configuration in the port profile data structure includes one or more of:
quality of service (QoS) configuration;
Fibre Channel over Ethernet (FCoE) configuration;
virtual LAN (VLAN) configuration; and
security related configuration.
6. The switch of claim 1 , wherein one or more of the port configuration applied to the ingress switch port is specific to the frame's source MAC address.
7. The switch of claim 1 , wherein the port profile data structure is applied to the ingress switch port within a predetermined time period after the frame is received.
8. A switching system, comprising:
one or more member switches;
a storage device residing on a respective member switch of the switching system and configured to store:
a port profile data structure specifying a set of port configuration corresponding to a plurality of media access control (MAC) addresses;
a second data structure mapping a respective MAC address of the plurality of MAC addresses and a corresponding virtual local area network (VLAN) identifier to a same policy group identifier; and
a control module residing on a respective member switch of the switching system and configured to:
determine that:
a frame's source MAC address is associated with the port profile data structure; and
the frame's source MAC address is in the plurality of MAC addresses mapped to the policy group identifier; and
in response to the determination, apply the port profile data structure to an ingress switch port of the frame, wherein applying the port profile data structure sets the port configuration specified in the port profile to the ingress switch port.
9. The switching system of claim 8 , wherein the switching system is a fabric switch;
wherein the storage device in a respective member switch stores the port profile data structure in response to the member switch being a member of the fabric switch.
10. The switching system of claim 8 , wherein the control module is further configured to, in response to the determination, apply the port profile data structure to an egress switch port of the frame, wherein applying the port profile data structure sets the port configuration specified in the port profile to the egress switch port.
11. The switching system of claim 8 , wherein the frame's source MAC address is a MAC address of a virtual machine.
12. The switching system of claim 8 , wherein the set of port configuration in the port profile data structure includes one or more of:
quality of service (QoS) configuration;
Fibre Channel over Ethernet (FCoE) configuration;
virtual LAN (VLAN) configuration; and
security related configuration.
13. The switching system of claim 8 , wherein one or more of the port configuration applied to the ingress switch port is specific to the frame's source MAC address.
14. The switching system of claim 8 , wherein the port profile data structure is applied to the ingress switch port within a predetermined time period after the frame is received.
15. A method, comprising:
storing in a storage device a port profile data structure specifying a set of port configuration corresponding to a plurality of media access control (MAC) addresses;
storing in the storage device a second data structure mapping a respective MAC address of the plurality of MAC addresses and a corresponding virtual local area network (VLAN) identifier to a same policy group identifier;
determining that a frame's source media access control (MAC) address is associated with the port profile data structure;
determining that the frame's source MAC address is in the plurality of MAC addresses mapped to the policy group identifier; and
in response to the determination, applying the port profile data structure to an ingress switch port of the frame, wherein applying the port profile data structure sets the port configuration specified in the port profile to the ingress switch port.
16. The method of claim 15 , further comprising, in response to the determination, applying the port profile data structure to an egress switch port of the frame, wherein applying the port profile data structure sets the port configuration specified in the port profile to the egress switch port.
17. The method of claim 15 , wherein the frame's source MAC address is a MAC address of a virtual machine.
18. The method of claim 15 , wherein the set of port configuration in the port profile data structure includes one or more of:
quality of service (QoS) configuration;
Fibre Channel over Ethernet (FCoE) configuration;
virtual LAN (VLAN) configuration;
security related configuration.
19. The method of claim 15 , wherein the port profile data structure is applied to the ingress switch port within a predetermined time period after the frame is received.
20. A switching means, comprising:
a storage device means for storing:
a port profile data structure means specifying a set of port configuration corresponding to a plurality of media access control (MAC) addresses; and
a second data structure means mapping a respective MAC address of the plurality of MAC addresses and a corresponding virtual local area network (VLAN) identifier to a same policy group identifier; and
