400 series Speed and Duplex

[clindberg]

I don't know why this is so difficult to find documented. It seems like networking 101.

But please verify for me:

406v2 - 100mb FULL duplex ports

412 - 100mb HALF duplex ports

Thanks for the consistency Avaya. . .

It is documented in the IP Office installation manual.

412

LAN RJ45 socket. These ports form a managed layer 3 Ethernet switch. The ports are halfduplex
10/100Mbps auto-sensing, MDI crossover ports.

406

LAN These ports form an unmanaged layer 2 Ethernet switch. The ports are full-duplex
10/100Mbps auto-sensing, auto-MDI/MDIX.

BAZINGA!

I'm not insane, my mother had me tested!

 

[clindberg]

Thanks for the quick response


"auto-sensing" Ha!

I have yet to install an IP office that autonegotiated properly with one of my switches.

 

[tlpeter]

What kind of switches?
I only have had auto sensing issues with cheap crappy switches.


BAZINGA!

Brand new Cisco 2960s. They cost more than the IP office.

 

[tlpeter]

Then you better lock the ports
I think you can do that on the IPO but you need to DTE in to the unit.
I never tried to change it so it will be on your own risk


BAZINGA!

[clindberg]

If I lock them on the cisco switch it's usually enough. What threw me is that the last one I installed was a 412 which I researched as being half duplex. I just installed a 406 and assumed it was the same. Threw me a curve.

 

[tlpeter]

Only the 412 as far as i know.
I never understood why but the are EOS so i don't care anymore


BAZINGA!

[clindberg]

EOS = Rock Bottom Discount PBX.

We are hopefully retiring in the next year

Weird, Port 8, configured as VLAN2 will not come up as 100 full even though port 1 does. And I'm getting collisions that seem to suggest it only supports half duplex.

 

[tlpeter]

I think this is why:


Note: Once LAN2 has been enabled on the system erasing the configuration back to
factory default will not remove the LAN2 setting. When the setting is enabled it is
written to FLASH so that the Ethernet switch is programmed before the main IP
Office code is loaded. When the IP Office configuration is erased the system restarts,
reads the setting in FLASH and then sets up a LAN2 port in the default configuration.
If you want to remove the LAN2 setting from a defaulted configuration you should untick
the ‘Use Port 8 as LAN2’ checkbox, save the configuration, restart the IP Office
and then default the configuration.

BAZINGA!

[clindberg]

The think is I WANT LAN 2 set up. It was whether it supports 100mb Full or not. When I force my switch to 100 the port goes dead.

It is working, but seemingly only supports 10half. And why did the IPoffice hardware people not put in any software to monitor networking errors???

 

[tlpeter]

You could try to use monitor and then set the filter for the tab "interface"
i believe you can select the lan port you want.
