Rev. A | 83 of 86

This anomaly list describes the known bugs, anomalies, and workarounds for the switch.

Analog Devices is committed, through future silicon revisions, to continuously improving silicon functionality. Analog Devices tries to ensure

that these future silicon revisions remain compatible with your present software and systems by implementing the recommended workarounds

outlined within this section.

Table 36. Statistic Counters for Per Stream Filtering and Policing Function (Qci)

Background

Statistic counters gathered for debugging and diagnostic purposes are not presented per the 802.1Qci specification.

Issue

Statistic counters not provided per the IEEE 802.1Q specification. This issue does not impact operation of the filter, gate, or flow meter

function or proper flow of the traffic across switch.

Stream filter: statistic counters (0 to 31) are indexed by StreamID, instead of the stream filter ID. Because there can be multiple stream

filters associated with a stream ID, therefore, multiple stream filters could increment the same counters.

Stream gate: statistic counters are indexed by their own identifiers (0 to 15) instead of the active stream filter (0 to 31).

Flow meter: statistics are indexed by their own identifiers (0 to 7) instead of the active stream filter (0 to 31).

Implications: stream gate and flow meter statistics are not linked to the active filter. In addition, there are fewer counter entries available for

both.

Workaround

None.

Related Issues

None.

Table 37. PRP Function Handling of Traffic in a Misconfigured Network (Wrong LAN Connections)

Background

In PRP mode, if a port receives a frame with a PRP RCT tag with a wrong LAN ID, the switch increments the counter but incorrectly

performs a duplicate discard and strips the PRP trailer.

Issue

As a result, the host SAN receives only a single copy of the frame with the PRP RCT trailer removed, rather than two copies. Frames

arriving with a wrong LAN ID is a misconfiguration of the network. There are error counters in place to detect this condition and allow the

host to handle it accordingly.

Workaround

Error counters are available for the host to manage this situation at the application level.

Related Issues

None.

Table 38. PRP Traffic with Wrong LSDU Size in the PRP Tag Gets Dropped

Background

PRP frames with wrong LSDU size is dropped.

Issue

IEC 62439-3:2021 Section 4.2.7.5.1 and Section 4.2.7.5.3 indicate frames with the wrong LSDU size in the PRP tag are to be forwarded to

the upper layers. If a peer device transmits PRP frames with the wrong LSDU size in the PRP tag, the switch configured as a PRP DANP

or PRP RedBox device drops those frames to the host processor and locally attached SANs as long as those frames arrive within the age

out time (that is, lreDupListResideMax).

Workaround

None.

Related Issues

None.

Table 39. FRER Frame Without CB Tag Is Modified by the Transmit Transform

Background

Frames matching the stream entry with no CB-tag gets corrupted.

Issue

Applying a sequence recovery to a frame that has no CB-tag results in the frame getting corrupted. This scenario is not expected in

a properly configured FRER network because identified frames have an existing CB-tag. The ingressing frame must match an existing

stream entry with a transmit transform to remove the CB-tag. In the event such an untagged frame arrives and matches a stream entry,

the switch forwards the tagless frame, and increases the packet and encoding error counts; however, the Ethertype gets corrupted, and six

bytes are removed from the end of the frame.

Workaround

None.

Related Issues

None.
