It feels good to get a good description along with detail down to the next track.

I did well when I read thoroughly and understand immediately that is good for us, especially me.

Extreme / Avaya / Nortel Ethernet Switching / ERS 5500 spanning tree
« Last post by beconnect on January 18, 2018, 06:39:49 AM »
Hi Guys

Need to connect two fiber cables from 2 switches on the 5 Floor to a stack in the  floor, for redundancy.

Only need to check Spanning tree on that ports correct?

For sure that if everything is correct on STG config one of the links will be down ( waiting for the other to go down to come up)

IS that correct?

See simple foto with connections below in attach.

Extreme / Avaya / Nortel Ethernet Switching / Re: ERS5000 LACP Clarification
« Last post by krc on January 17, 2018, 12:57:15 PM »
Top of my head:

add vlan(s) to your uplink ports (keep one down on the remote side so there is no loop)
- on each port for the LAG, checkBox lacpactive, aggregation, (timeout depends on your infrastruture)
- make sure the ActorAdminKey is the same on all ports within the LAG
- Set admin state for lacp enable on each port of the LAG
- under global MLT/LACP settings, make sure the mapping is set for that KEY.
- bring up 2nd link if all is well (would try in lab environment 1st if possible).
- under global MLT/LACP, check the LACP Ports tab for state

Also, how are you testing speed ? not to sound like an a$$, but I had one user argue with me because they could never get more than 1Gig on a speed test, but when I asked what they were testing from and what is your connection speed for that NIC, he clued in.

Pretty sure the stack count and code level have to be the exact same as it was when backed up.

Extreme / Avaya / Nortel Ethernet Switching / ERS5000 LACP Clarification
« Last post by eangulus on January 10, 2018, 09:46:18 PM »
Hi. Firstly, I am a beginner in advanced/enterprise networking. I know a little and some of the basics.

I have a stack of 6 ERS5500 switches and have managed to configure them OK via the WebUI. I am a complete noob when it comes to the CLI.

I Thought I managed to get LACP setup, but all tests are showing me speeds consistent with a single 1Gb Network.

I have a Synology NAS connected via 3x1Gb links and configured for LACP. I also have 2 Cisco Servers running XenServer with 2 3x1Gb Links, again configured for MAC-Based LACP.

I am trying to determine if my setup is good on the switch end before I move on to further diagnose. I am getting very confused about MLT and LACP, as I understand MLT is a proprietary feature. But when I enable LACP on a few ports, it shows up as an MLT link.

I simply want to get more bandwidth to and from my NAS and XenServer.

When testing I have used LAN Speed Test on a VM and testing to a network location on the NAS. I am getting around 800-850Mbps. I thought this was good until I realised that there is no change with or without LACP. So my guess is this could be 3 times faster.

In my searches, all I find is MLT and LACP and I think I need LACP static to avoid the MLT stuff, but am not sure and can't find a clear enough answer or how to.

Any advice would be much appreciated.

Hi

Came across a post on this forum suggesting to use the command
show spanning-tree rstp status
to identify rstp root bridge. Hence issued the command on network switches (mixture of 5010, 5020, stacked, unstacked running  v6.3.6.016 / v6.2.4.010)
The output is confusing because my understanding is that the output
Stp Root cost: 0
indicates the switch to be a root bridge.(Unless my understanding is incorrect) And there can only be one root bridge but many switches are showing Stp Root cost: 0. 
Below is the command output. Please advise how can the root bridge be identified?

Avaya (Blue) / Nortel IP Telephony / Avaya 1230 Startup Tones
« Last post by exsmogger on January 08, 2018, 08:06:43 AM »
Hello all.  I have an Avaya 1230 IP phone working on my BCM50 R6.  I was wondering if anyone knew of a way to disable the annoying startup tones that play during bootup just after "Application starting" appears on the display?  Perhaps there is a command in SSH or a line in the users.dat file that would turn it off.  Thanks.

I believe JRE 6.4 will work although you'll need to make some changes to the lib.security file if I recall properly.

You'll need Firefox 51 or earlier to enable the Java plugin.

There are a great many articles on the net detailing how to-do this.

Cheers!

I'm guessing you are using the binary backup... would suggest you use the ASCII backup and see what needs to be cleaned up. It sounds like the old switch you have used to be part of a stack and that was never cleaned up.

Cheers!
