Leaving SFP ports out of the table is deliberate for now, and being able to
force a module's speed belongs in a feature of its own rather than arriving
inside a fix, so that half goes again.
What remains is the off-by-one: createPortTable() read pState[i] where the
array is filled by portNum - 1, so every row started out showing the next
port's link speed until the first refresh corrected it. The debug line above
it goes too; it printed a third index, pState[i-2].
The port table skipped every SFP port outright, so on a SWTGW218AS the
uplink simply was not there. Of the seven columns only Set Speed is
meaningless for a module: the name, the link speed and the devices behind
the port all are worth showing, and the name in particular was accepted on
another page and then never displayed anywhere. The MTU table further down
the same page has always drawn the port, so the page disagreed with itself.
Give an SFP port its row and leave the three control cells empty. Whether
speed and disable should work for a module is a separate question and
untested, so this does not offer a button for it.
The link state was read one port too far. main.js fills pState by
portNum - 1, updatePortTable() reads pState[i-1], and createPortTable()
read pState[i], so every row started out showing the next port's link
speed until the first refresh corrected it. On the last copper port that
meant showing the uplink's speed. Feeding the real status.json of a nine
port switch through both versions:
expected 7 7 7 1 7 1 7 7 6
before 7 7 1 7 1 7 7 6
after 7 7 7 1 7 1 7 7 6
Dropping the skip also removes a trap rather than papering over it.
updatePortTable() addresses rows as tbl.rows[i], which only lined up with
port i because the SFP port happens to be last on this board. With a
module in the middle every row after it would have been off by one.
Adds a Connected devices column to the Port Configuration table, fed by
the shared walkL2() helper. A port with a single MAC behind it shows the
MAC directly; several are shown as a count with the full list in the
cell tooltip, since picking one of many to display would suggest it was
"the" device. The walk restarts 15 seconds after each completion and
starts 3 seconds after page load to stay clear of the initial status and
MTU requests. A walk that ends without ok keeps the previous cells,
since an incomplete table would blank ports that have devices behind
them. Translations for the three languages included.
This reduces the number of .js which are pulled by the browser
when loading a http page, which should reduce the loading time.
Also prepare for device-dependent logical to physical port
mappings.
