FYI 4.1.6 has been pulled from the Nortel site. 4.1.5.4 is now recommended.

Nortel re-sold the Airespace solution until Cisco paid too much for it. Uses dumb AP's and central "security switches" using LWAPP to manage. If you open one of the AP's there is a jumper that will return the AP's to Fat status :-) Also has a survey mode jumper. It was known as the 2200 series...

Updating code on a stack of 3 5510's takes about 68 seconds from traffic stop to traffic restart. Management IP takes longer to come back to life. Granted you have to do it twice if you need the diag. I have not timed a stack of 8. Doubt it would be drastically longer.

In read-only can you see if the password for telnet is turned on? Maybe only the console has a password.

This appears to have morphed it to an 8600 conversation. With that in mind and the last posts, I am interested in the XP induced VRRP problem. We have been slowly converting to XP and have unexplained VRRP events. Related?? Hmmm.. What have you noticed, and what version of 8600 code are you...

One additional thought: What type of PC/device are you using? There have been some PC's and cards made with a 25pin serial connection. I believe you could tell by the gender of the 25pin connection if it was serial or parallel, but it absolutely escapes me as to which is which. Anyone who...

Don't think you can. HT is designed for a serial interface, as well as the things you are trying to connect. There may be some serial-to-parallel devices you could try. (MicroCenter etc) What are you trying to do? If you have a USB port available, there are pretty cheap USB-serial devices...

No need to "create" a stack. The switches will figure it out when you boot after you have connected them. Several item to note. The switches should be on the same version of code, at the very least they must be on the same version of stack code, both either v1 or v2. You can see this on the...

A quick look at the 2.1 release notes does not specifically address a CPU fail-over issue. Maybe the Nortel guys know more, if they have said it will fix the problem. We have had 2 chassis failures in the 8600 world. Have you replaced that(2 bad ones is unlikely)? Maybe 1 test could be to...

Untagged BS450 ports can not be members of more than 1 port based VLAN. I'm not sure just what you are trying to do. Maybe some more background will gleen a workable solution. Unlike a hub, a switch basically limits an individuals "view" to their own traffic, excepting broadcasts. What type...

dane775 is correct in the above post. One thing I can add is, I have had different results using different tftp servers. The most common fix for me has been to put the file I want to send into the root directory of the tftp server box, and set tftp server default to same.

Are the 3 IP based VLANs really subnet based VLANs?

You may want to drop this in the Linksys forum. Include Model #

Sounds quit complicated. You mention that there are 9 protocol based VLAN's on the 8600. What are the 9 different protocols that are defined for the VLAN's? What type are the other 25 routers? Are they directly connected to the 8600? Brief CPU spikes are not uncommon in large networks, are...

How large is your network? We have had single 8600's in place on large installs and the CPU's have never worked very hard.

What code do you have on the 8600s? Are you using SMLT on the two 8600's for the gig links to the stack(s)MLTs?

Are your 8600's setup with an IST between them? Would you be able to provide some more detail about your BPS to 450 cascades. How many stacks do you have? We have a mountain of BPS and 450 stacks(same rev's of code) and have not had any problems like what is happening to you. Has it worked...

If the IP addresses that you use are all in the same range, make it one VLAN. If they are in different ranges you need to set up routing between the 2 VLAN's, and set up DHCP forwarding as described above. Hope this is helpful..

I believe that the 8600 ships setup for a null cable on the console port. There is a DTE-DCE switch on the SF console port, so if your cable does not work, try flipping the switch. Hope this is helpful

Passports do not support additional IP ranges on a VLAN or multiple port based VLANs on one port without tagging. Multi-netting in Nortel lingo, IP secondary address in Cisco lingo. (BayRS did support multi-netting). I assume the 2 network IP ranges are overlaid on the same backbone. What do...
