1:1 Card Protection ONS 15454

Hi All,
I am trying to understand the reason why the protect card/port shouldn't be in OOS(Out of service) to avoid any traffic loss even though the protect card is not switching traffic in ONS 15454 as stated below
"When a protection switch moves traffic from the DS3-12 working/active card to the DS3-12 protect/standby card, ports
on the new active/standby card cannot be taken out of service as long as traffic is switched. Lost traffic can result
when a port is taken out of service even if the DS3-12 standby card no longer carries traffic."
Thanking You

Native fibre channel using SL cards on ONS 15454.

Greetings,
I normally hang out in the Storage Networking forum but I thought this would be a good spot to ask a question.
We current have a dark fibre connection between our sites and have issues with our Brocade switches (yeah, they should be MDS) with buffer zero problems. We want to add more bandwidth for our ISL's and we have a couple of ONS 15454's hanging around in racks in our datacentres.. I have been looking at the SL cards for the 15454 and would like to know if anyone has had success with them. I need to do synchronous True Copy between the storage at both sites for a new project. We are using async now but that wont be good enough.
Any comments would be welcome.
Stephen

Stephen,
I don't have any SL cards in production, but do have ML cards, and a myriad of TXP/MXP's on MSTP platforms.
I can tell you, the ML card does a decent job with distance extension is turned on. I have a few STS-24's extended across 400-500KM span lengths for TAPE drives across ML cards and see consistently high throughput.
Measured latency across a 70km span was about 600us with an ML card. Pretty close to an equivalent circuit built across a Muxponder.
I would venture to say, the only concern that you may have with synchronous replication is the latency.
Regards,
Tom.

10G Bigger Pipe on ONS 15454

I have two STM4 SDH capacities and one STM16 SDH spanning two cities over different service providers. See Attachment, I have two Cisco ONS 15454 in two cities, one of the ONS is connected to a GSR router serving as core router while the second ONS is connected to a 7609-S serving as MPLS-PE router, their is DOT1q tagging transparently carried over the SDH circuits between the two routers. I want to make these capacities one big Ethernet pipe (10G) at both ends, this fat pipe should be able to carry multiple VLANs between the attached routers at both ends. Is this achievable? if yes what kind of Ethernet cards do I require on ONS and the routers? Any supporting document will be highly appreciated.

"but I am not sure if Cisco produce a 10G ethernet cards for ONS 15454?"
cisco also have 10G Ethernet card but it can go over DWDM box not STM 16 & STM 4.
I am not sure what ECi and Huwai are offering but i am sure of one thing that even if they give you 10G Ethernet card but you CANNOT map that single Ethernet card to your 3 STM interfaces (1 STM 16 & 2 STM 4). As far as i know you can map one ethernet port to one SDH port (either 1 STM 16 or 1 STM 4).
Before believing ECI & Huwaei discuss that solution with some people, as I know one thing there can be lot of strings later on.
They say totally different thing before but once you buy that then you get to know the real features. You will have the feature but with lot of if & but.
What you can do is if that makes sense in your case, take 10 1Gig (Total 10G) ethernet card then you can map 3 ethernet ports to 3 STM interfaces you have.
Whats is the max speed your provider can give you? If they give you 10G SDH then see if you can get 10G POS card for your routers.
You can think of DWDM solution, this way you can take 10G direct over a wavelngth and lot many later. What is the distance between your 2 ONS?

ONS 15454 SDH with 2 ML cards connected to the same RPR

I was wondering if I could connect 2 ML cards installed in the same ONS 15454 to the same RPR ring. Thanks!

Bob,
If you are wanting to tie the ML100 and the ML1000 into the same RPR Ring, then you have do do it with the POS interfaces.
For Example:
ML 100 POS 0 - North Microwave
ML 100 POS 1 - connect RPR to ML 1000 POS 0
ML 1000 POS 1 - South Microwave
North Microwave connects RPR to South Microwave
This creates a single Loop or Ring
It sounds like you are using your ML1000 as a Spur to another location. In order to create an RPR ring, you must have the cards physically connected to each other in a continuous ring.

CTC shows a card that isn`t instaled on the ONS 15454

On the ONS 15454 I have a TCC2P card on slot 11, slot 7 is empty, but when i access the CTC i see the card on slot 11 in white, and i also see a TCC2P card on slot 7 in light blue, so how can i stop ctc showing the card on slot 7

you can't do that, thats how the system is designed.

Mixing SONET/DWDM Cards in a ONS 15454

All,
To my understanding, there are some limitations to mixing SONET line cards with DWDM line cards in the same ONS 15454 chassis. I believe one of the limitations had to do with the line card placement versus a OSC-M and OSC. I can't remember the draw backs of doing the above, but there was some negative.
Are there any more draw backs, limitaitons or gotchas?
Also, generally, the optical engineers I spoke to recommended never mixing the cards and keeping them in seperate chassis.

Hello Jason,
Mixing SONET/SDH and DWDM functions in the same chassis is a supported configuration on the ONS 15454 platform.
As was stated in the other posts, you would have to install the SONET/SDH crossconnect cards in the chassis in order to have the HO/LO functionality.
You are right, that there is an impact on the card placement in the chassis, however you can force the planning tool (Cisco TransportPlanner) to leave the required slots for the XC cards empty when designing the DWDM network.
The model described so far is what is commonly referred to as a "hybrid" node.
There is one other element in the toolchest however - The ADM-on-a-Blade (see http://www.cisco.com/en/US/partner/prod/collateral/optical/ps5724/ps2006/ps5320/product_data_sheet0900aecd805f0e80.html). This network element is an integrated part of the DWDM personality of the ONS 15454 and provides SONET/SDH switching and client ports on the blade. Please note however, that this network element provides only a high-order crossconnect.
It is generally true that one would usually keep SONET/SDH network elements in separate chassis. However, from a network management perspective these separate chassis can form a single node.
Hope that helps

ONS 15454 ML Card Question

I have an ONS 15454 with an ML-100
and an ML-1000 installed. I hav
e a WAN on the ML-100 that I would like to
add a spur to from the ML-1000. How can I accomplish th
is?
Thanks,

Hi Colin,
so you want to add two more ONS devices in an existing ring.
if you can provide a topology it will be helpful,
if you just want to add two more ONS in existing ring, it will no cause any issues,
we just have to take care of circuits and need to build them from TL1 in these new nodes.
but please send topology to get an clear view.

ONS 15454 error message

Hi Expert,
I have a problem with ONS 15454 error message. My CTM server detected MINOR error message "Peer to Peer Slot Communication Failure". Affected object is SLOT-1 which is OPT_BST. The alarm ID is 200551. What caused this error appear and any workaround to solve this problem?. Your kind attention is much appreciated.

Although the following alarm is not identical to the one you identified, this seems to indicate the a peer "communication failure" is hardware related.
2.5.237 PEER-NORESPONSE
Default Severity: Major (MJ), Non-Service-Affecting (NSA)
Logical Object: EQPT
The switch agent raises a Peer Card Not Responding alarm if either traffic card in a protection group does not receive a response to the peer status request message. PEER-NORESPONSE is a software failure and occurs at the task level, as opposed to a communication failure, which is a hardware failure between peer cards.
Hope this helps....

Cisco ONS 15454 SONET MSPP

I am doing a school research project in which I am setting up an OC-192 ring for a company (contract work through AT&T). I have chosen to use the Cisco ONS 15454 SONET MSPP as my platform. The company currently has locations in Chicago and Philadelphia and connects them through an OC-12C ATM connection and they are looking to add 2 gigabit ethernet connections.
My question is what cards and parts will I need for the Cisco ONS 15454 SONET MSPP, and how much will everything cost? I have been searching the internet for components and prices and I have found it extremely difficult to find any information. Any help or tips anyone can offer would be greatly appreciated.

Nick,
You can find the HW specifications for various ethernet cards for the 15454 at the following location.

6509 to ons 15454 showing not connect.

Were running into a problem moving from an oc48 to oc192. In our web enviornment we have a Front-end switch and a Back-end switch in two data centers that are 10 miles apart. Were running a "gigaman" betweent the two. On both ends we have cs6509's and were patched into the Gbic interface on the sup2's. This fiber is ran to are lec's ons 15454 which I have no visibility into. We are unable to get a connection on the 6509's. Were doing basic layer 2 trunking between the switches. Sbc tested from the fiber on the switch to a loop on the other switch and was able to test clean. This worked on the oc-48 but are switches were not connected to a cisco ons. Any suggestions would be apperciated. You can also email me at [email protected] or AIM jjt8572.

Have you checked that you have matched the physical media framing - e.g., LAN PHY needs to speak to LAN PHY (or WAN PHY to WAN PHY). Typically the ONS 15454 would be looking for a SONET frames (WAN PHY) while a Cisco 6509 would be sending 10 Gigabit Ethernet LAN frames (LAN PHY). That is, unless you specifically choose an interface for your 6509 such as the XENPAK-10GB-LW (10GBASE-LW XENPAK Module with WAN PHY for SMF). From that product's data sheet: "The Cisco 10GBASE-LW Module supports a link length of 10 kilometers on standard single-mode fiber (SMF) (G.652).
WAN-PHY is intended to allow the transport of 10 Gigabit Ethernet over a traditional SONET/SDH infrastructure. The purpose of WAN-PHY is to render 10 Gigabit Ethernet compatible with SONET STS-192c format and data rate, as defined by ANSI, as well as the SDH VC-4-64c container specified by ITU."
One can also use Cisco ONS transponder cards that will wrap LAN PHY framing in something like G.709 encapsulation to allow it to be transported through a DWDM network.

Upgrade ONS 15454 M12 TCC2P from 9.4.03 to 10.0.11

Hello,
quick question.
I have in my lab one M12 subrack with only-one TCC2P card and I try to prepare software upgrade in customer network.
I read all procedures at: http://www.cisco.com/c/en/us/td/docs/optical/15000r/upgrade/guide/b-454a10-0-1-upgrade.html
My troubles started at point where I can select node where the software must be downloaded. The window is empty.
Target version is "ons15454.DWDM.Lite.K9.R10011.pkg".
Any idea?
Thanks
kvapa

Hi Emyrsonn,
I hope this ONS 15454 upgrade tool can help you answering all your questions
http://www.cisco.com/web/techdoc/optical/15000r/upgrade/guide/ons-upgrade.html
It seems like you should be able to directly upgrade from 9.1.x to 9.2.2.
Please let me know if you have any comments on that.
Hope it helps!

ONS 15454 design question

I have an ONS 15454 with 2 OC192 circuits that terminate into it. One goes to a downstream ONS and another to the upstream.
I need to extend the existing ring to 2 more ONS devices, but I am not sure if it is going to work the way I want it to.
Right now, each VTS24 circuit on the OC192 is associated with a POS interface on the ML1000 cards. So POS1 goes upstream, POS0 downstream (unprotected). The ML1000 is int turn trunked to a 3750 L3 switch that has the bridge groups and layer 3 addressing assigned. This is Ring0
I need to extend this ring, so obviously I will need 2 additional OC192 cards, but do these new circuits need to be associated with new POS interfaces? In other words, will I need 2 additional ML1000 cards, and if so, how would I trunk to the switch? Am I going to get into some loopy topology here?
I am new to this system, so any advice would be great.

Hi Colin,
so you want to add two more ONS devices in an existing ring.

Cisco ONS 15454 SDH

Hi,
i have 3 sites connecting together with SDH 15454 site A-B with STM-1 and from site B-C STM-16,i want to Aggregated hand-off E1's from Site A-C so site B will be trasparet site for this link.
to be source of link on site A and Drop on site C.
any help to achive this.
there is already cricte between site B-C.

You will need to verify that the cross-connect card in the ONS 15454 (sites B & C) have VC-12 grooming capabilities (XC-VXL and CX-VXC will support VC-12 grooming).
The ONS is designed to groom lower rate signals to higher rate speed lines. Thus, you should be able to aggregate the E1s from the ISPs STM1 with the E1s from Site B and drop them at Site C.
You will need to add an STM1 card(s) to Site B. Your ISP will need to provide the mapping structure of the STM1, so you can understand where the VC-12s, which contain the E1s, are located in the payload. You will then create circuits to map each E1 (the incoming VC-12s within VC3/VC4) from you ISPs STM1 at Site B, to the appropriate VC-12 on the outgoing STM16 line heading toward Site C. At Site C, you will need to map the VC-12s on the STM16 line to the appropriate port on an E1 line card.
I hope this helps. Otherwise, you will need to have someone locally assist you in the explanation.

ONS 15454 shows up as "unknown" after power outage

We had a power outage that took down a ONS 15454 in a remote facility. Upon restoring power and powering-up the unit, it shows up in CTC as grey with "Uknown2" as the name.
I had someone reseat the TCC card, but it still comes up as unknown.
Has anyone seen this? Any suggestions (the device is hours from me)

Try and restart CTC session and clear CTC cache
Can you ping the node
Check to see if the node is in the OSPF routing table
Can you access via CTC locally
Is your CTC terminal directly connected or does it go via a firewall
Probably resolved now how did you resolve it?

ONS 15454 problem turning up OC12

Board.
I am trying to turn up an OC12 (non-concatenated) that is muxed from a OC48. The OC48 terminates on an ONS 15454 on both sides. From there we run SM fiber to Cisco 12000 series onto an SM OC12/SMT4 Line card on both sides too.
My settings for the ONS are as follows:
Type=STS
Size 12C
Dir = 2way
We see on one Cisco UP/DOWN, and on other Cisco Down/Down
Does any on this forum have any tips at all?

Which OC12 LC do you have on the 12000?
CHOC12/STS3-IR-SC
4OC12E/POS-IR-S
4OC12X/POS-I-SC-B
etc
