etherStatsBroadcastPkts
Address:
1110 0010
The value in this register represents the total number
of valid packets received that were addressed to a
broadcast address.
etherStatsMulticastPkts
Address:
1110 0011
The value in this register represents the total number
of valid packets received that were addressed to a
multicast address.
etherStatsCRCAlignErrors
Address:
1110 0100
The value in this register represents the total number of
packets received that were between 64 and 1518 octets,
inclusive, and had either FCS errors or alignment errors.
etherStatsUndersizePkts
Address:
1110 0101
The value in this register represents the total number of
packets received that were less than 64 octets long, but
were otherwise error free.
etherStatsOversizePkts
Address:
The value in this register represents the total number of
packets received that were greater than 1518 octets
long, but were otherwise error free.
1110 0110
etherStatsFragments
Address:
The value in this register represents the total number of
packets received that were less than 64 octets long, not
including the preamble or SFD, and had either an FCS
error or an alignment error.
1110 0111
etherStatsJabbers
Address:
The value in this register represents the total number of
packets that were greater than 1518 octets long and
had either FCS errors or alignment errors.
1110 1000
Note:
This differs from the IEEE definition of Jabber.
etherStatsCollisions
Address:
1110 1001
The value in this register represents the total number of
collisions on the IMR2 device.
etherStats64Octets
Address:
The value in this register represents the total number of
packets (including error packets) that were 64 octets long.
1110 1010
etherStats65to127Octets
Address:
1110 1011
The value in this register represents the total number of
packets (including error packets) that were 65 octets to
127 octets long inclusive.
etherStats128to255Octets
Address:
1110 1100
The value in this register represents the total number of
packets (including error packets) that were 128 octets
to 255 octets long inclusive.
etherStats256to511Octets
Address:
1110 1101
The value in this register represents the total number of
packets (including error packets) that were 256 octets
to 511 octets long inclusive.
etherStats512to1023Octets
Address:
1110 1110
The value in this register represents the total number of
packets (including error packets) that were 512 octets
to 1023 octets long inclusive.
etherStats1024to1518Octets
Address:
1110 1111
The value in this register represents the total number of
packets (including error packets) that were 1024 octets
to 1518 octets long inclusive.
Activity
Address:
The value in this register represents the total number of
octets that were active on the IMR2 device.
1111 0000
Register Bank 7: Management Support
These registers control packet compression and error
sampling. The Management Support Registers can be
accessed by writing 0000 0111 to the C Register and
then writing the register address to the C Register.
Device ID
Address:
The Device ID Register is a read/write register. It is an
8-bit register and contains the assigned ID number of
the IMR2 device. This number is transmitted as part of
the tag field by the Packet Report Port.
1110 0000
Sample Error Status
Address:
Sample Error Status gives statistical data on packets that
have errors. It is a 4-deep 8-byte FIFO. Each read re-
quires accessing the data register eight times. The ac-
cess can jump to the next level of the FIFO in the middle
of a read by writing any value to the node processor port
with the C/D pin HIGH. If the node processor port is ac-
cessed (with the C/D pin LOW) after the last byte is read,
