Monitoring and Configuring the Forwarding Cache

dialog box parameters
Table 22-2. Frame Forwarding Statistics Dialog Box Parameters
Parameter Defines the...
FIRE Fabric
Port/Chip Index Fabric port associated with the layer 3 module. The P580
switch has 13 fabric ports: the P882 switch has 33 fabric
ports. The supervisor module slot uses one fabric port: the
media module slots each use two fabric ports. The
supervisor module slot uses fabric port 1, the first media
module slot uses fabric ports 2 and 3, and so on.
L3 Total (T2) Total number of frames received on the fabric port.
L3 Frame Cache
Hits Number of packets received on the fabric port that were
successfully matched against existing forwarding entries in
the layer 3 (L3) address cache.
Percent Cache
Hits Total percentage of successful matches between packets
received on a fabric port and the percent of those packets
that matched the L3 address cache entries.
L3 Slow Path
Frames Number of frames received on a fabric port that were not
successfully matched against existing forwarding entries in
the layer 3 (L3) address cache. Subsequently, these frames
were forwarded to the supervisor module (slow path). All
frames sent to the supervisor module are routed in
software.
If this number is very large and the module associated with
the fabric port is licensed, you may want to enable a short-
lived protocol filter to conserve the forwarding engine
resources. For information on how to enable a short-lived
protocol filter, see “
Configuring Short-Lived IP Protocol
Filters ” in Chapter 12 , “ Configuring IP Routing .”
Percent Slow
Path Total percentage of unsuccessful matches between packets
received on a fabric port and the percent of those packets
that did not match the layer 3 address cache entries.
L3 Drop Frames Number of layer 3 frames that were dropped. For example:
They did not match the layer 3 address cache entries.
Percent Drops Total percent of layer 3 frames dropped.
RX Frame
Count (T2) Total number of frames received on a fabric port.
L2 Frame Count
(T2) Number of layer 2 frames received on a fabric port that
were forwarded on to an associated VLAN.
