| CiscoPortPinningMode |
|
| 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. |

| ciscoEthernetFabricExtenderMIB |
1.3.6.1.4.1.9.9.691 |
| The MIB module for configuring one or more fabric
extenders to connect into a core switch. Since fabric
extenders might not be manageable entities, this MIB is
assumed to be instrumented on the core switch. A fabric
extender may be hardwired or preconfigured with a list of
uplink ports. These uplink ports are used to connect to a
core switch. A fabric extender is assumed to be directly
connected to its core switch. Each physical interface on
the core switch is assumed to be connected to one and only
one fabric extender.
When an extender powers up, it runs a link local discovery
protocol to find core switches. The extender puts all
available self identification in its discovery report.
The core switch, depending on configuration, uses the
extenders identification to accept or deny an extender
from connecting. A fabric extender may be connected to
different core switches via different uplink ports. In
that case, each core switch's instance of the MIB may
refer to the same extender.
Ports on core switch used to connect to extenders
are known as Fabric ports. A fabric port may be a physical
interface or a logical interface such as an EtherChannel.
An extender may connect into a core switch via more than
one fabric port. Non fabric ports on an extender are
typically used to connect hosts/servers. |

| cefexBindingTable |
1.3.6.1.4.1.9.9.691.1.1.1 |
| This table has the binding information of a
'Fabric Port' to 'Fabric Extender' on a
'Extender Core Switch'. Each entry in this table
configures one fabric port.
A core switch does not accept fabric extender
connections into its fabric ports unless the
extender matches an entry in this table. Once matched,
the extender is identified by the instances of the
cefexBindingExtenderIndex in the matching row.
The matching criteria and values to match for
each fabric extender are specified in a row in the
cefexConfigTable. Each row in the cefexConfigTable
is indexed by cefexBindingExtenderIndex. Each row
in this table has an unique cefexBindingExtenderIndex
value, therefore, providing the linkage between
the two tables.
It is expected that user first creates a row in
the cefexConfigTable for a specific cefexBindingExtenderIndex,
followed by creation of the corresponding row in
this table for the same cefexBindingExtenderIndex..
If a row in this table is created and if there is
no corresponding row created in the cefexConfigTable,
then the agent will automatically create a row in the
cefexConfigTable with instance of every object in this
row initialized to the DEFVAL. |

1.3.6.1.4.1.9.9.691.1.1.1.1.1 |
| This object is the index that uniquely identifies an entry in
the cefexBindingTable. The value of this object is an IfIndex
to a fabric port. By creating a row in this table for
a particular core switch interface, the user enables that
core switch interface to accept a fabric extender. By default,
a core switch interface does not have an entry in this table
and consequently does not accept/respond to discovery
requests from fabric extenders. |

1.3.6.1.4.1.9.9.691.1.1.1.1.2 |
| The value of cefexBindingExtenderIndex used as an
Index into the cefexConfigTable to select the Fabric
Extender configuration for this binding entry. However,
a value in this table does not imply that an instance with
this value exists in the cefexConfigTable.
If an entry corresponding to the value of this object does
not exist in cefexConfigTable, the system default behavior
(using DEFVAL values for all the configuration objects as
defined in cefexConfigTable) of the Fabric Extender is
used for this binding entry.
Since an extender may connect to a core switch via
multiple interfaces or fabric ports, it is important all
the binding entries configuring the same fabric extender
are configured with the same extender Index. Every
interface on different fabric extender connecting into
the same core switch is differentiated by its extender id.
To refer to a port on the extender, an example
representation may be extender/slot/port. Extender id
values 1-99 are reserved. For example, reserved values can
be used to identify the core switch and its line cards in
the extender/slot/port naming scheme.
cefexBindingExtenderIndex identifies further attributes
of a fabric extender via the cefexConfigTable. A user
may choose to identify a fabric extender by
specifying its value of cefexConfigExtendername and/or
other attributes. |

value of cefexBindingExtenderIndex expressed as 4 digits.
For example, if cefexBindingExtenderIndex is 123, the
default value of this object is 'FEX0123'. This object
allows the user to identify the extender with an

| This object allows the user to identify number of
fabric ports to be used in distribution of pinned
non fabric ports. As described above, pinning is the
forwarding model used for fabric extenders
that do not support local forwarding. Traffic
from a non fabric port is forwarded to one
fabric port. Selection of non fabric port pinning
to fabric ports is distributed as evenly as
possible across fabric ports. This object
allows administrator to configure number
of fabric ports that should be used
for pinning non fabric ports. |
