CiscoPortPinningMode

• Base type Enumeration

This denotes the mode of re-pinning. Re-pinning defines how traffic forwarding is altered between fabric extender and its core switch in case of a fabric port state change. For fabric extenders that do not support local forwarding, they do not perform normal address learning and forwarding as a traditional 802.1d compliant bridge. A method named 'pinning' is used instead to dictate forwarding behavior. That means, traffic from a specific non fabric port is always forwarded to its pinned fabric port (no local forwarding). Each non fabric port is 'pinned' to one of the fabric ports. Load balancing aspects affecting pinned fabric port selection is dictated by internal implementation. If a particular fabric port fails, all the non fabric ports pinned to the failed fabric port may need to be moved to the remaining fabric ports, if any. Note that traffic distribution within a fabric EtherChannel does not utilize the 'pinning' method. The traditional hash of MAC address, IP address and TCP/UDP port is used to select fabric port within a fabric EtherChannel. It is planned that more enumeration will be introduced in subsequent updates. static(1) - If this mode is chosen, non fabric ports are not re-pinned to other fabric ports in case of fabric port failure.
