| Initial version of this MIB module.
Phy definition
Throughout this document phy is used as an abbreviation
for Physical Interface. In particular it refers to a
physical ATM jack on a Catalyst 5000 ATM card. This card
can be fitted with either one or two physical jacks, only
one of which may be active at any given moment. The second
phy serves as a redundant connector to the ATM backbone.
Note, however, that for logistical reasons, each phy has
a separate ifIndex.
Support of the phy by ifTable
The dual phy entity on the c5K ATM line card is managed
using the ifTable. Specific interpretations of ifTable
for the dual phy entity are as follows.
Object Use for dual phy entity
====== =======================
ifIndex Each phy entity is represented by an ifEntry.
ifDescr Description of the phy entity.
ifType The value for the phy entity is other(1).
ifSpeed See [1].
ifPhysAddress An octet string of zero length, per [1].
ifAdminStatus See [1].
ifOperStatus See [1]. In addition, note that a phy can
be in the up state but still not be the
active phy. However, the active phy will
always be up.
ifLastChange See [1].
ifName See [1].
ifLinkUpDownTrapEnable disabled(2).
ifHighSpeed See [1].
ifConnectorPresent true(1).

1.3.6.1.4.1.9.9.60.1.1.1.1.6 |
| The Bit Interleaved Parity 8 is an error checking code
applied for quick isolation of faults. Each bit in the
B octets is set to 1 or 0 as necessary to obtain even
parity over the previous frame. The calculated BIP-8
code for frame N is compared with the BIP-8 code extracted
from the B1 byte of frame N+1. Differences indicate that
a section level bit error has occurred.

based on even parity. The calculated BIP code for frame N
is compared with the BIP-8/24 code extracted from the B2
byte(s) of frame N+1. Any differences indicate that a
line layer bit error has occurred.

| The number of bits (binary 000 to 1000) in the previous
BIP-8 that didn't match the even parity check are inserted
by the transmitter. The receiver checks for this in the
M0/M1 byte of the frame. A non-zero value (legal range
is binary 0000 - 1000) indicates a line layer error in
the remote end. Any other value is treated as no error.

| The Header Checksum (HCS) is a CRC-8 calculation over
the first 4 octets of the ATM cell header. The received
HCS is verified using the polynomial x^8 + x^2 + x + 1.
The coset polynomial x^6 + x^4 + x^2 + 1, is added
(modulo 2) to the received HCS octet before comparison
with the calculated result. Cells with single bit error
in the HCS byte are corrected. Cells with more than one
bit error in the HCS byte are uncorrectable.

| Returns the ifIndex of the phy which is the preferred
active phy. A value of 0 indicates that no phy is
currently active.
Setting this object to a value different from its current
value causes the ATM module to make the indicated phy active,
and the active phy inactive.
Setting this object to its current value has no effect.
After performing the phy change, the agent will update
all phy information (including cadpStatOperActivePhy)
and send a ciscoAtmDualPhyChange trap. |
