Configuring CEF on MSFC2/MSFC3
CEF is permanently enabled on MSFC2/MSFC3. No configuration is required to support CEF for
PFC2/PFC3A.
Note
The
ip load-sharing per-packet
,
ip cef accounting per-prefix
, and
ip cef accounting non-recursive
Cisco IOS CEF commands on MSFC2/MSFC3 apply only to traffic that is switched by CEF on
MSFC/MSFC3. The commands do not affect traffic that is switched by CEF for PFC2/PFC3A on the
supervisor engine.
Specifying CEF Maximum Routes
Note
This feature is only available with Supervisor Engine 720.
To specify the maximum number of routes that can be programmed in the FIB TCAM for a protocol, use
the
set mls cef maximum-routes
{
ip
|
ip-multicast
}
routes
command. The syntax is as follows:
•
ip—Specifies IP MLS.
•
ip-multicast—Specifies IP multicasting MLS.
•
routes—Specifies the number of routes that can be programmed in the FIB TCAM.
