You may have a loop in your network that is bringing the switch CPU to it's knees. You could probably connect a laptop to any of the switch ports and run WireShark to see if there are any loops/broadcast storms.

You need to either configure the phone through the handset (WLAN ESSID, Security, etc) or you need to connect the handset via USB to a PC and use the Handset Administrator. It sounds like you've completely skipped configuring the handset with the necessary WLAN information. Good Luck!

It might be a code issue with the BayStack products but definitely not the Passport (Ethernet Routing Switch). If it's possible I would setup a sniffer on the edge switches to confirm that your telnet (TCP/23) packets are actually making it to the switches. Do you have a single VLAN for your...

HmmHmm... that's an interesting problem. You mention "password" changes but it sounds like you were previously using RADIUS authentication? What version of software are you running on the 470s? What version of software are you running on the 8600s? When you serial up does the log reveal...

This could be a classic ARP/FDB issue with your core... what version of software are you running in your core? If you dump the ARP and FDB tables from the core switches do they point to the SMLT port that connects the edge switch or do they point to the IST ports? It could also be a MLT...

Are you sure the PVID is correct on the switch ports? Cheers!

Yes, the feature is not available in 5.0 only in 5.1 and beyond. Cheers!

Hmmm... if you are running 5.1.3 software you should have that feature in the software. Where you at the config prompt? 5530> 5530> enable 5530# configure terminal 5530(config)# clock time-zone EST -5 5530(config)# clock summer-time EDT date 8 Mar 2009 2:00 1 Nov 2009 2:00 +60 Good Luck!

Here's how to set the parameters from the CLI interface; clock time-zone EST -5 clock summer-time EDT date 8 Mar 2009 2:00 1 Nov 2009 2:00 +60 You can just change the parameters to match your timezone. Cheers!

There is a problem with 3.7.3 and that's why it no longer appears on the website. Nortel will be releasing a bulletin very shortly documenting the issue. Cheers!

I don't believe the 470 is EoL... it's certainly not EoS.

It looks like v3.7.3 was pulled from Nortel's website. You'll need a support contract in order to download any of the currently available releases. I would stick with 3.7.2 although I'll need to inquire as to what happened with 3.7.3 Cheers!

Perhaps they meant to say "Layer 2" traffic?

I believe the latest version of software for the ERS 4500 series now supports ADAC but not sure about the ERS 2500 series. You definitely need the ports configured as untagPvidOnly of the PC won't know what to-do with the 802.1q tagged frames. You didn't mention if you are trying to use LLDP-MED...

There was a bulletin posted to Nortel's website concerning a port bouncing issue that was resolved in 5.0.1.0 software. I believe they are still working on the lane lockup issue but are hopefully to have it resolved in 5.1.0.0 software...

Well 4.1.8.2 has been rock solid so I'm hoping that 5.0.1.0 will pick-up from there... it took them long enough but I hopefully that things will be very stable.

Are you using the latest and greatest firmware for the 6140? We had a voice quality issue using the latest software release for our Motorola Wireless LAN switch until we upgraded to the latest release for the 6140, I believe it was firmware release 115.019. You should really have a TFTP...

Here's an example of a Perl script that using SNMP and TFTP to upgrade large number of switches in an automated fashion. http://mysite.verizon.net/michaelfmcnamara/files/switchupgrade.pl.txt You would need to adapt the script to your environment and if you are not familiar with Perl or...
