Table 38: Configuring Multicast Fields (continued)
Option
Flow Map
Forwarding Cache
62
Function
Enables you to set up multicast flow
maps to manage a subset of multicast
forwarding table entries. For example,
you can specify that certain forwarding
cache entries be permanent or have a
different timeout value than those of
other multicast flows that are not
associated with this flow map .
Enables you to configure multicast
forwarding cache properties. These
properties include threshold suppression
and reuse limits, and timeout values.
You can specify a value for the threshold
to suppress new multicast forwarding
cache entries and an optional reuse
value for the threshold at which the
device begins to create new multicast
forwarding cache entries. If you configure
both reuse and suppression values,
configure a reuse value that is less than
the suppression value. The suppression
value is mandatory. If you do not specify
the optional reuse value, then the
number of multicast forwarding cache
entries is limited to the suppression
value. A new entry is created as soon as
the number of multicast forwarding
cache entries falls below the suppression
value. You can also specify a timeout
value for all multicast forwarding cache
entries.

comment.
Bandwidth—Specify the
bandwidth property of the
multicast flow map.
Forwarding Cache—Specify the
forwarding cache properties of
entries defined by a flow map. You
can specify a timeout of never to
make the forwarding entries
permanent, or you can specify a
timeout from 1 through 720
minutes.
Policy—Specify the flow map
policies.
Redundant Sources—Specify the
addresses for use as backup

defined by a flow map.
