Field Name Field Description
Filter statistics Receive
subsystem. The filtering is done by the content-addressable memory (CAM)
on the PIC. The filter examines a packet's source and destination MAC addresses
to determine whether the packet should enter the system or be rejected.
Input packet count
that the filter processed.
Input packet rejects
either the source MAC address or the destination MAC address.
Input DA rejects
destination MAC address of the packet is not on the accept list. It is normal
for this value to increment. When it increments very quickly and no traffic is
entering the routing device from the far-end system, either there is a bad ARP
entry on the far-end system, or multicast routing is not on and the far-end
system is sending many multicast packets to the local routing device (which
the routing device is rejecting).
Input SA rejects
source MAC address of the packet is not on the accept list. The value in this
field should increment only if source MAC address filtering has been enabled.
If filtering is enabled, if the value increments quickly, and if the system is not
receiving traffic that it should from the far-end system, it means that the
user-configured source MAC addresses for this interface are incorrect.
Output packet count
hardware.
Output packet pad count
minimum Ethernet size (60 bytes) before giving the packet to the MAC
hardware. Usually, padding is done only on small ARP packets, but some very
small IP packets can also require padding. If this value increments rapidly,
either the system is trying to find an ARP entry for a far-end system that does
not exist or it is misconfigured.
Output packet error count
the filter was given to transmit. These packets are usually aged packets or
are the result of a bandwidth problem on the FPC hardware. On a normal
system, the value of this field should not increment.
CAM destination filters, CAM source filters
dedicated to destination and source MAC address filters. There can only be
up to 64 source entries. If source filtering is disabled, which is the default, the
values for these fields should be 0.
