Forwarding Profiles allows for the
configuration of the Unified Forwarding Table (UFT) so that it suits deployment
requirements. A predefined forwarding profile can be selected based on scaling
requirements. This UFT partition is configured during the initialization process
and is
effective after a system reload.
The Unified Forwarding Table (UFT) can house
both logical Layer 2 and logical Layer 3 forwarding tables. By combining these
tables
into a single configurable resource, more memory resources can be assigned to heavily
utilized logical tables at the expense of less-used tables. In this manner, the
different scaling requirements for Layer 2 (MAC addresses) and Layer 3 (IPv4 and
IPv6
routes) can be managed. The shared table can be partitioned so that it can be used
for
Layer 2 tables, Layer 3 tables, Algorithmic Longest Prefix Match (ALPM) tables,
or Field
Processor Exact Match (FPEM) tables, according to the needs of the user.
Four predefined forwarding profiles are
supported. The following table shows information about the predefined forwarding
profiles and the maximum system entries set for each profile.
Forwarding Profiles is supported for the following
RUCKUS ICX platforms:
ICX 7850
ICX 7550
Note: The default forwarding profile is profile1.

7550 Devices for a Switch Image
Complete the following steps to change a
forwarding profile. The following example configures the predefined forwarding profile
“profile2” for an ICX
7850 device. The default forwarding profile "profile1" is overwritten and the
maximum system (system-max) parameters are reset.
