# v1.0.8 — Both management links tested at once, and ARP stops looking like packet loss
|
||||
|
||||
## ✨ New features
|
||||
|
||||
**Both management NICs are pinged simultaneously and continuously**
|
||||
* `mgmt_ping_monitor.sh` no longer alternates fixed bursts. `start` configures both NICs, then pings from each at the same time and keeps accumulating until stopped — so a soak-long run is one continuous measurement rather than a series of snapshots.
|
||||
* `stop` renders a report into the log: the last 20 entries per NIC, each one's ping statistics and PASS/FAIL, then `ip -s link show` for both interfaces.
|
||||
* Every line is timestamped, and a request that got no reply prints a marker instead of merely being absent — a drop is visible in the tail, not inferred from a gap in the sequence numbers.
|
||||
* `status` shows both pids and how many replies each NIC has received so far, which is the quick way to see one side is dead without waiting for the report.
|
||||
|
||||
**The USB stress target is detected, not assumed**
|
||||
* New `usb_target.sh` reports an inserted USB device's node, mount point or by-id path. Script B asks it for the node and builds the stress command from the answer, so a stick that enumerates as `sdb` no longer sends a write test at whatever `/dev/sda1` happens to be.
|
||||
* It excludes whatever disk backs `/` and `/host` — this platform can boot from a USB DOM, which also reports as USB — refuses to guess when several USB disks are present, and when it mounts, verifies the result is actually writable rather than trusting that `mount` succeeded.
|
||||
|
||||
**BMC I2C integrity is exercised through the soak**
|
||||
* `bmc_monitor.sh` is back in the run and now writes two complementary patterns to a BMC scratch register and reads each back. One pattern alone cannot catch a bit stuck the same way it was written; repeating the pair through the soak turns an intermittent I2C fault into something the log records rather than something the tester has to witness.
|
||||
|
||||
**Test artefacts leave the DUT with the run**
|
||||
* Script C copies `bmc_poll.log` and `mgmt_ping.log` into the job directory before it is archived to USB, so the monitors' output travels with the `bgctl` job logs.
|
||||
* DDR stress now runs continuously instead of stopping after 100 passes, matching the other soak loads.
|
||||
|
||||
## 🐛 Bug fixes
|
||||
|
||||
**Three FAILs that were not link faults**
|
||||
* A bench run reported `FAIL=3` with zero NIC errors, zero drops and sub-millisecond replies. Every failure was missing exactly `icmp_seq=1` and nothing else: once the neighbour entry for the target expires, the first echo request is spent resolving ARP and `ping` counts it as loss. A discarded warm-up ping per NIC now absorbs that, which is what lets the loss threshold stay at zero and still mean something. Raising the threshold instead would have hidden genuine single-packet loss.
|
||||
|
||||
**Job logs were being cleared before they were collected**
|
||||
* Script C ran `bgctl reset --yes` while killing processes — before the job directory is copied to USB. Moved to after the archive, so a run's own logs are collected before anything clears them.
|
||||
|
||||
**The fan controller was bound twice**
|
||||
* One of the two MAX31790 controllers received a second `bind` immediately after the first, which could only fail because the driver was already attached.

||||

|

**After copying to the DUT:**
|
||||
|
||||
```bash
|
||||
chmod +x ~/Blanton_Script/*.sh # see below
|
||||
grep -rlU $'\r' ~/Blanton_Script # expect no output
|
||||
```
|
||||
|
||||
`mgmt_ping_monitor.sh` no longer re-execs itself, so `bash mgmt_ping_monitor.sh start` works without the execute bit. `bmc_monitor.sh` and `usb_target.sh` still need it — and neither git (mode 100644) nor a Windows/USB copy carries it. Without the `chmod`, `start` fails with `Permission denied` and the later `cat` finds nothing: **the section ends up empty and nothing reports an error.**
|
||||
|
||||
## ⚠️ Before you run
|
||||
|
||||
* **Declare the switch population.** `SWB_UNIT0` / `SWB_UNIT1` in `config.ttl` say which switch units this DUT has. Traffic and the readiness gate both follow them; with neither set the traffic stage is skipped rather than failing against hardware that is not there.
|
||||
* **Set the fan speed you want.** `FAN_SPEED` in `config.ttl` is applied at the start of every run.
|
||||
* **Management connectivity is in use, not preserved.** Both NICs are up and pinging — drive the run from the serial console.
|
||||
* **If the two management NICs share a subnet, keep `ARP_STRICT=1`.** Otherwise the target's ARP can be answered by either NIC and a reply may arrive on the one that did not send. Check `nic_tx` / `nic_rx` on the RESULT line: they are that interface's own counter delta.
|
||||
* **Two settings persist to `config_db.json`** and survive a reboot: LLDP is left disabled and the 100G uplinks are left configured. Restore them before the DUT moves on.

# Notes : - Both NICs are brought up and LEFT up. Addresses and default
|

# routes are applied with iproute2 `replace`, which is idempotent:
|
||||
# re-running a round does not stack duplicate addresses or routes.
|
||||
# - The default routes carry different metrics (100 / 200), so the
|
||||
# lower one wins for off-subnet traffic. They do NOT decide which
|
||||
# NIC a ping leaves by: `ping -I <iface>` binds to the device.
|
||||
# - !! SAME-SUBNET WARNING !! With both NICs up on one subnet the
|
||||
# target ARPs for the address and Linux may answer from either
|
||||
# NIC, so replies can arrive on the wrong one and the result is
|
||||
# not attributable. ARP_STRICT=1 sets arp_ignore/arp_announce to
|
||||
# stop that. Leave it on unless the two NICs are on separate
|
||||
# subnets, as in the iproute2 example this was modelled on.
|
||||
# - Each leg logs `ip -s link show <iface>` and the TX/RX packet
|
||||
# delta across the burst, which is the direct evidence of which
|
||||
# NIC actually carried the traffic.
|
||||
# - The first pings after bringing a link up are lost to ARP, not to
|
||||
# the link: a bench capture showed 4x "Destination Host
|
||||
# Unreachable" on the first burst and 0% loss on the very next
|
||||
# one. LINK_SETTLE_SEC absorbs that; it is not packet loss.
|
||||
# Notes : - Both NICs are configured with iproute2 `replace`, which is
|
||||
# idempotent, and both are left up. On a shared subnet the target's
|
||||
# ARP can be answered by either NIC, so ARP_STRICT keeps each one
|
||||
# to its own address.
|
||||
# - ARP WARM-UP: the first packet after a neighbour entry expires is
|
||||
# spent resolving ARP and is counted as loss. On the bench this
|
||||
# produced three FAILs whose only missing packet was icmp_seq=1,
|
||||
# every time, with zero NIC errors or drops. One discarded ping
|
||||
# before the measured run removes that artefact, which is what lets
|
||||
# MAX_LOSS_PCT stay at 0 and still mean something.

# V1.0.0 20260824 Initial Version (ifconfig, one NIC at a time)

One round = 10G leg then 1G leg, each pinging its own target. Both NICs are
|
||||
brought up and left up; addresses and routes are applied with
|
||||
"ip address/route replace", so repeating a round does not stack duplicates.
|
||||
The report holds, per NIC, the last ${TAIL_LINES} entries and the ping
|
||||
statistics, then "ip -s link show" for both interfaces.
|
||||
|
||||
If both NICs share a subnet, keep ARP_STRICT=1 -- otherwise a reply can come
|
||||
back on the NIC that did not send it. Check nic_tx/nic_rx on the RESULT line:
|
||||
they are that interface's own counter delta across the burst.
|
||||
|
||||
Edit the User Configurable Section at the top to change interfaces, addresses,
|
||||
targets, prefix lengths, gateways, metrics or the packet count.
|
||||
Both NICs are used at once, so management connectivity is in play -- drive
|
||||
this from the serial console. Edit the User Configurable Section at the top
|
||||
to change interfaces, addresses, targets or the ping options.

# its device node, its mount point, or both.
|
||||
#
|
||||
# stdout : requested value(s) only, for $(...) capture

#
|
||||
# Usage : usb_target.sh [-o dev|mnt|both|id] [-n] [-r seconds]
|
||||
#
|
||||
# -o dev print partition device node (e.g. /dev/sda1)
|
||||
# -o mnt print mount point (e.g. /mnt/usb) [default]
|
||||
# -o both print "<dev> <mnt>" on one line
|
||||
# -o id print stable by-id path (/dev/disk/by-id/...)
|
||||
# -n detect only, do not mount
|
||||
# -r sec udev enumeration wait, default 15
|
||||
#
|
||||
# Exit : 0 success
|
||||
# 1 no USB mass-storage found
|
||||
# 2 multiple USB disks detected (refuse to guess)
|
||||
# 3 no usable filesystem on the device
|
||||
# 4 mount failed
|
||||
# 5 mounted but not writable
