Hi,

FYI I was able to reproduce the issue and fix it:

set the LACP keys once more on the ports.

So my normal procedure was - with a fully configured and working LACP trunk as starting point:
no lacp aggr enable
add new vlans to the ports
lacp aggr enable



Last weekend we had to add some more VLANs on our backbone links (2x10g between the two stacks) and yes, the show mlt output stopped even listing those two.
Out of paranoia I re-did some of the LACP settings, including the LACP admin key.

4526GTX(config)#interface fastEthernet 1/25-26
4526GTX(config-if)#lacp aggregation enable
4526GTX(config-if)#lacp key 42
4526GTX(config-if)#lacp mode active
4526GTX(config-if)#lacp timeout-time short


With that extra step the bug is avoided.
For clarity - in a show running-config you'd still see the LACP key. but something was off, and re-configuring the same key does fix it.

Nortel / Avaya Ethernet Switching / ACL in Nortel BackBone

I want to learn smth about ACL in Avaya 8800 series Backbone. İs ACL block the flow in software or hardware level? Do you know anything about this?

Thanks

I already have the ports with data vlan as Pvid. So i think i only need the config of voice and fhe flexible setting.

Thanks for your share ;)

Here's how it's explained:
Code: [Select]
switch(config)#vlan configcontrol ?
  automatic  AutoPVID and automatic change to membership of port-based VLANs
  autopvid   Automatic change to PVID
  flexible   No restricts or automatic changes
  strict     AutoPVID and restrictions imposed on adding port to VLAN and
             changing tagging
Flexible isn't going to change anything until you tell it to, which is what I like.  If I add a VLAN to a port that didn't have said membership, it has changed the membership to the new VLAN as the PVID, which wreaked havoc for me until I reproduced in the office. 
I don't want to be caught by surprise when I add a VLAN and it uses that new VLAN as the PVID, which ... in my earlier years of working with the equipment hit me once and then I put in safeguards to stop that from happening.  I haven't had any issues with the flexible setting and have used it ever since.

Hi,

Ok..

now I am aware of this :).

But isn't autopvid and the fliexible setting similar?

Correct - there are a few commands that get you to the same conclusion - some of the commands also depend on your revision of code.  Yes, yours will work just fine.
My only other comment is because we have been burned on not checking it out prior to making some of the VLAN changes...
I ensure that prior to running those commands, I also do a
Code: [Select]
vlan configcontrol flexibleI've been guilty of getting all my stuff together, then having the config set for
Code: [Select]
vlan configcontrol autopvid and ... all the ports we change with the voice VLAN become the new PVID on the ports and we cause a connectivity issue for all devices connected to said ports.  Been there, done that :(
So now when I write my configs for copy/paste operations, I always include that line so I ensure I'm not going to accidentally change 200 VLANs on accident and kick myself out of the switch or anything.

Thanks for the help

Just something like this, i assume.


vlan ports 1-46 tagging unTagPvidOnly filter-unregistered-frames disable
!
vlan create 40 name "Voice" type port voice-vlan

It's a sound plan - a few notes:
  • On all your ports with the phones sharing computers, you would likely want to ensure they are set for UntagPvidOnly
  • Ensure that when you create your VLAN for the phones, you add it as voice-enabled, like I'll show below
Code: [Select]
vlan create 40 voice-vlanYou probably already considered those; just adding it.  I know you can run a script to enable IP Office and the like - I just don't end up using it - we have a phone guy that handles that.

Hi All

We have 4800 switches and we are going soon to install IP office 500.

Could you help validating this:

1. create vlan 40 ID for voice

2. Already have vlan 140 for data.

3. set all ports for users where the phone connects to TAG pvid and set pvid to Vlan 140 ( data)

4. pass the VLan 40 in all trunks

5. DHCP for the phones  is done on IPoffice.

IS this ok?

Regards
