| Description | The Fibre Channel Routing tables for the
locally managed switches. This table lists all the
routes that are configured in and/or computed by any
local switch for any Fabric.
Such routes are used by a switch to forward frames (of user
data) on a Fabric. The conceptual process is based on
extracting the Destination Fibre Channel Address Identifier
(D_ID) out of a received frame (of user data) and comparing
it to each entry of this table that is applicable to the
given switch and Fabric. Such comparison consists of first
performing a logical-AND of the extracted D_ID with a mask
(the value of t11FcRouteDestMask) and second comparing the
result of that 'AND' operation to the value of
t11FcRouteDestAddrId. A similar comparison is made of the
Source Fibre Channel Address Identifier (S_ID) of a frame
against the t11FcRouteSrcAddrId and t11FcRouteSrcMask values
of an entry. If an entry's value of t11FcRouteInInterface
is non-zero, then a further comparison determines if the
frame was received on the appropriate interface. If all of
these comparisons for a particular entry are successful,
then that entry represents a potential route for forwarding
the received frame.
For entries configured by a user, t11FcRouteProto has
the value 'netmgmt'; only entries of this type can be
deleted by the user. |
