Forwarding Profiles allow 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.
Forwarding Profiles are supported for the
following RUCKUS
ICX platforms:
ICX 8200
ICX 8100
ICX
7850
ICX 7550
Three predefined forwarding profiles are
supported. The following tables show information about the predefined forwarding
profiles and the maximum system entries set for each profile.
Note: The default forwarding profile is profile1.

Maximum System Entries Set for a Forwarding
Profile for ICX
7550 Devices
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.
