Sharing my earlier experiences with
the hidden telnet interface on the Netgear GS716T switch
was appreciated by someone else with a Netgear GS110p switch:
"Hidden" CLI interface on Netgear GS110TP. So I guess this is
a feature on multiple netgear switches.
And that article made me look at the firmware version, finding in the release
notes for the newer version:
New Features:
* Add IPv6 management, IPv6 ACL, and IPv6 DiffServ support.
I like that feature a lot! And indeed, after upgrade and setting the IPv6
management address:
$ telnet .... 60000
Trying ..:1234...
Connected to ..:1234

Kudos to netgear for making this switch IPv6 enabled!
Update 2014-03-02
And.. back to the previous firmware. Plugging in a cable on a port that
was long idle wasn't detected at all. That's not what I have a switch
for at home, it should detect it when I plug in a device at the living
room table. Disabling the 'green' option (power-saving when idle) on
the switch did not change this behaviour.
Now running:
Software Version............................... 5.0.3.5
Operating System............................... ecos-2.0
One upside: I can have two firmware versions in the switch and make one or
the other active. So I switched back to the previous one easily: set the
other as active and initiate a reset.
There are other 5.4 firmwares available from netgear but 5.4.2.10 is the
first version with IPv6 management.
Update 2014-03-09
I opened a case with Netgear about this. Their suggestion was to do a factory
reset.
Easier than it sounds, the house uplink and wireless depend on this
switch being configured with the house vlans. It is possible to download
the full configuration in text format and upload that again. So I did a
whole planned change with minimal downtime:
- Download configuration
- Prepare cabled system with tftp server with the configuration available
- Set new firmware active
- Select factory reset
- Upload saved configuration to the switch
- Test new configuration
I noticed the short-cable settings weren't saved so I went all out with
short-cable and green ethernet settings on all ports but the trunk.
Let's see what happens.
Update 2014-03-10
And a day later the switch with the 5.4.2.10 firmware works fine, detecting
link on all ports. And the "green" settings work:

I had to find out why "short cable" wasn't being activated, as some cables
are short enough:
(Broadcom FASTPATH Switching) #show green-mode 0/13
Energy Detect Admin Mode....................... Enabled
Operational Status......................... Inactive
Reason..................................... Link Up
Auto Short Reach Admin Mode.................... Enabled
Force Short Reach Admin Mode................... Disabled
Operational Status......................... Inactive
Reason..................................... Not At GIG speed
EEE Feature.................................... Not Available
Cumulative Energy Saving (W * H)............... 0
Time Since Counters Last Cleared............... 1 day 2 hr 27 min 32 sec
So 'short cable' is only active at gigabit and there is no cable at gigabit
and 'short'.
