Virtual 7750 SR Available in 12.0.R4

[Stoffen]

Thank you zeips!!

I was able to set up a second 5 port card on card 1 mda 2. I just needed to add some adaptors to the qemu config page. Having a second mda expands the lab potentials greatly.

Any hints on how to slot a sonnet card in slot 2? It would be great to be able to set up api labs for training.

Hi.
To have a second slot (IOM/IMM) you need to change to distributed setup, using one VM for CPM/SFM and one VM per IOM/IMM.
This also requires a valid license.
Even if you have a license, I'm not sure if this will work in GNS3.
Would advise you to set it up in KVM/QEMU if you want to do it distributed.

Hi, trying to get a few 7750 devuices running in GNS3, i think im nearly there but when hitting the console connection, im getting the message

"Alcatel7750timos12.0R6-1" requires 2048MB of RAM to run but there is only 1747MB - 12.7% of RAM left on gns3vm"

Any ideas how to resolve? Is it something on the Virtual Machine, are there any changes i can make to any settings to get it to run? Is there an OS which will allow me to run MPLS / VPLS / VPRN for a max of maybe 8 devices around the 1700MB mark (that I can dowmnload for free?)

Hi, dont know if you have found the solution to this, but you only need to allocate more memory to your GNS3-VM in GNS3.
I've set mine to 12 Gigs.

Hi guys, Can someone share with me and image of the 7750 SR so i can upload it in GSN3?

Hi @Stoffen

Have you had a chance to look at this or ever heard anyone else complaining about the same ?

I've got another setup where i use access ports this time and configure the same Lags on both sides. Again where there is sap Lags configured under the interfaces , i can't ping within a p2p interface, when i take the access ports out of the Lags the pings start working.

Just wondering if anyone came across this before ?

Thanks
Ed

Hi Guys ,

I'm having the same problem with LACP. When i assign the LAGs that i've created to the network ports , I can't ping the p2p interface although the LAGs are both up on each side and assigned on the both interfaces. When i take the ports out of the Lag and assign one of them each to the same interfaces, the ping starts working.

I can access to the ALU documentation, so can anyone point out where i can find necessary information that says LACP is not supported or there's limited support for that in VSR-OS release ? Release notes doesnt seem to say much.

Thanks
Ed

Hi.
Was looking for it, but unable to find the one with the limitations explained.
Here is the newly released VSR install guide, and the limitations in that one, does not mention LACP.
I haven't tested R14 vSIM yet, so cant tell if it will work or not..

Will look more thoroly for it tomorrow..

@EdHunter;
Just tested on SROS 16 in GNS3.

LAG with LACP
IES with sap lag.
Mode access, encap null

Result: 64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=13.8ms.

If you are using KVM/QEMU with linux bridges, I know there is some issues with slow protocols, like LACP, that might cause issues for you.
OpenVSwitch or similar implementation on Linux might solve that headache.


Configuration, identical on both sides except for IP:

And for the sake of the argument, changed from access to network, still encap null.
router interface test on both sides.

Just did a test on SROS 13.0.R10, and there I do have some issues.

* LAG will not turn Oper Up unless different LACP admin keys
* When LAG is up, I cant get IP connectivity.

I can see ARP from SR01 to SR02.
SR02 responds, but SR01 does not seem to pick up the reply.

After investigating, I see that both devices are insisting on using the same MAC for the interface.
Change mac on one side, it works.

I've seen this behaviour on SROS 14 -> but never on 13.
When using ordinary ports, they do not choose the same MAC.

Perhaps this explains your issue?

With lag:

Code: Select all

*A:SR01# show router interface "test" detail | match MAC 
MAC Address      : 96:2b:ff:00:01:42    Mac Accounting    : Disabled

*A:SR02# show router interface "test" detail | match MAC 
MAC Address      : 96:2b:ff:00:01:42    Mac Accounting    : Disabled

With single port:

Code: Select all

*A:SR01# show router interface "test" detail | match MAC 
MAC Address      : 0c:e6:85:fd:f8:03    Mac Accounting    : Disabled

*A:SR02# show router interface "test" detail | match MAC 
MAC Address      : 0c:e6:85:72:31:03    Mac Accounting    : Disabled

Turing the LAG into access mode, create an IES and bind it to the lag, and the same thing happens.

Code: Select all

*A:SR01# show router interface "ies1" detail | match ignore-case mac 
MAC Address      : 96:2b:ff:00:01:42    Mac Accounting    : Disabled

*A:SR02# show router interface "ies1" detail | match ignore-case mac 
MAC Address      : 96:2b:ff:00:01:42    Mac Accounting    : Disabled

Changing to single port SAP and it all changes:

Code: Select all

*A:SR01#  show router interface "ies1" detail | match ignore-case mac 
MAC Address      : 0c:e6:85:fd:f8:04    Mac Accounting    : Disabled

*A:SR02#  show router interface "ies1" detail | match ignore-case mac 
MAC Address      : 0c:e6:85:72:31:04    Mac Accounting    : Disabled

So, I urge you to check your MAC address'es...
