Searching The Routing Cache For An Entry - Lucent Technologies Cajun P220 Operation Manual

Monitoring and Configuring the Forwarding Cache (Layer 3)
2. Use Table 11-3 to review the forwarding statistics:
Parameter
FIRE Fabric Port
L3 Total (T2)
L3 Frame Cache Hits
Percent Cache Hits
L3 Slow Path Frames
Percent Slow Path
L3 Drop Frames
Percent Drops
RX Frame Count (T2)
L2 Frame Count (T2)

Searching the Routing Cache for an Entry

To search the L3 address cache:
1. In the L3 Forwarding Cache section of the Web Agent window, click Entry
Search. The Route Cache Entry Search dialog box opens.
2. Select the search criteria you want to use to find more specific information on
available routes. For example, if you want to find all entries in the routing cache
that contain a VLAN entry of vlan_10.0.1.1, you would search by VLAN and
specify vlan_10.0.1.1 as your search value.

Table 11-3. Forwarding Statistical Parameters
Defines the...
Fabric port associated with the Layer 3 module. The switch has
13 fabric ports. Each module slot uses two fabric ports with the
exception of the supervisor module slot which uses one fabric
port. Hence, the supervisor module slot uses fabric port 1, the
next media module slot uses fabric ports 2 and 3, and so on.
Total number of frames received on the fabric port.
Number of packets received on the fabric port that were
successfully matched against existing forwarding entries in the
Layer 3 (L3) address cache.
Total percentage of successful matches between packets
received on a fabric port and the percent of those packets that
matched the Layer 3 address cache entries.
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.
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.
Number of Layer 3 frames that were dropped because they did
not match the Layer 3 address cache entries.
Total percent of Layer 3 frames dropped.
Total number of frames received on a fabric port.
Number of Layer 2 frames received on a fabric port that were
forwarded on to an associated VLAN.
