Multicast Pkts (Read-only)

The Multicasts ﬁeld displays the total number of good packets received

that were directed to a multicast address. The value of this ﬁeld does not

include packets directed to the broadcast address.

CRC Align Errors (Read-only)

This ﬁeld displays the number of packets with bad Cyclic Redundancy

Checks (CRC) received from the network. The CRC is a 4-byte ﬁeld in

the data packet that ensures that the data received is the same as the data

that was originally sent. Alignment errors are due to packets not sent to

higher level protocols in the correct order.

Undersized Pkts (Read-only)

The Undersized Pkts ﬁeld displays the number of packets received with a

valid CRC and whose size was less than the minimum Ethernet frame size

of 64 bytes (not including preamble).

Oversized Pkts (Read-only)

The Oversized Pkts ﬁeld displays the number of packets received with a

valid CRC and whose size exceeded 1518 data bytes (not including

preamble).

Fragments (Read-only)

This ﬁeld displays the number of received packets with less than the

minimum number of bytes, or received packets, were less than 64 bytes

(excluding framing bits), but including Frame Check Sequence (FCS)

bytes) that had a bad FCS, and an invalid CRC.

Jabbers (Read-only)

This ﬁeld displays the total number of packets that were greater than 1518

bytes and had either a bad FCS or a bad CRC.

Total Packets (Read-only)

This ﬁeld displays the total number of packets (including bad packets,

broadcast packets, and multicast packets) received on this interface.

NOTE It is normal for the Fragments ﬁeld to increment. This is

because the RMON agent increments the ﬁeld when runts are

detected (which are normal occurrences due to collisions) and

when noise hits occur.
