Virtual 7750 SR Available in 12.0.R4

[thecandymancan]

Yeah it works on the original version but not the extended model. I message Fred and see what he says.

[Stoffen]

Have anyone managed to get some redundancy stuff to work with the virtual SR's?
I know HA is stated as a limit in the releasenotes, but still it should be possible to do some, like MC-LAG / LACP.

I have a setup and have enabled LACP.
I can see LACP packets on the vnet interfaces from each router, but it does not enter the bridge that ties the vnet's together.
Using Centos 7

Does anyone here know how to enable LACP transparancy on Linux bridges?

I asked this in the Centos community as well, but no response so far.

I know mc lag doesn't work for sure. It's a limitation of the software. I remember trying to get lacp working for my lab prep but it didn't work. Configuration was 100% correct so I just used real hardware for that aspect.
Slow protocols tend to get dropped by a bridge that has the ability to support it in itself. Not sure on transparency in a linux bridge. Maybe qinq would work on the sr where the linux bridge is only aware of 1 tag?

I've actually gotten MC-Lag to work. You just need the two machines to have different Base MAC addresses.

When I first started I used centOS and they both had the same Base MAC, so the lag would be in standby on both machines. I then moved over to ubuntu with gns3 and for some reason I were able to create 4 machines with 4 different Base MACs, no idea how.

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,

Beginner questions:

1. What and how many cards or mdas can I use?
What is the limitation?

A:R1# show card state

===============================================================================
Card State
===============================================================================
Slot/ Provisioned Type Admin Operational Num Num Comments
Id Equipped Type (if different) State State Ports MDA
-------------------------------------------------------------------------------
1 iom3-xp-b up up 2
1/1 m5-1gb-sfp-b up up 5
1/2 m5-1gb-sfp-b up provisioned 5
(not equipped)
2 iom3-xp up provisioned 2
(not equipped)
2/2 m5-1gb-sfp-b up provisioned 5
(not equipped)
3 iom3-xp-b up provisioned 2
(not equipped)
4 iom3-xp up provisioned 2
(not equipped)
5 iom3-xp-c up provisioned 2
(not equipped)
A sfm4-12 up up Active
B sfm4-12 up down Standby
(not equipped)
===============================================================================
A:R1#

Is that a legal configuration? (I don't think so - not equipped.)
not-equipped means not usable and the virtual software is not able to use it?

2. Is there documentation about usable cards which can be pluggabled
into the router?

3. My A/1 port is working. But I can't ping anything:
PING 10.10.10.254 (ip of the mgmt port)
No route to destination. Address: 10.10.1.0.254, Router: Base.

I can SSH or telnet into the router.
There are these lines in bof:
address 10.10.10.254/24 active
static-route 10.10.0.0/16 next-hop 10.10.10.1

We have got some real 7705 SAR-8 and I'd like to learn TiMOS.

TIA,

Hi,

Can you give me some information about usable cards and mda-s?
How many slots can I use?

What does 'not equipped' mean?

[Stoffen]

Hi.
In unmodified setup your only option is IOM3-XP-B with m5-1gb-sfp-b MDA.

This give you the opportunity to use 6 ports.
1: CPM1 MGMT
2: 1/1/1
3: 1/1/2
..
6: 1/1/5

You can however modify the setup without a license.
This is done in the XML file of the VM.

There are some limitations on what you can modify.
If you modify the IOM + MDA (or IMM) card, then you will be forced to a CPM-2/SFM-2 setup with its limitations.
Ifyou modify the CPM/SFM slot, then you will not be able to modify the IOM / MDA. It's been a while since I did this, but as far as I recall, it ended up with unprovisioned / uninstalled IOM/MDA when SFM card was stated.

If you have licensed vSIM's, you can run a distributed model, where SFM/CPM runs a seperate VM, and IOM/IMM's run in seperate VM's.
One VM per card (not including MDA's).

The state "priovisioned / not equipped" only means its been configured in \configure card X, but XML setup has no information regarding the card. It will be the same in a real chassis. You can preconfigure a card, then install it physically at a given time.

I hope this answers your questions

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.

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..

TIA,

Thank your for your information about cards.

Can you tell me something about the above situation with the mgmt interface and the "no route ... " problem?
It is true no configured routes except the static in bof. If it is enough why I can't ping the host from which I
can SSH into the SAR?

TIA,
