| 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. |
