Latency in MXP on ONS 15454 MSTP

Hi!
Have a question concerning latency in MXP for ONS 15454 MSTP. How do you define and measure it? I mean in for MXP you basically mux many client signals in to one lambda. Since this muxing requires O-E-O process there got to be some latency? Or is the values to small that it become neglible and we dont have to worry about it. My customer is asking me this and I cant come up with a definitive answer. To me there's practically none, it work at optical level, as to determine latency it is enough just from looking and end-to-end ping result on client side. Apreciate your expert advice.

Dual Ring Capabilty for ONS 15454 MSTP

Hi!
I am designing a MPLS over DWDM network which consist of one core DWDM ring and several regional DWDM ring using ONS 15454 MSTP. I would like to connect the regional ring to the core ring via P router in this case Cisco 12406GSR. My major concern now is to reduce the number of boxes especially on the DWDM part. Can an ONS box connect to 2 DWDM ring, regional and core directly without using a router in the middle. Apreciate your expert opinions. Thanks.

Core DWDM ring and Regional DWDM ring are built using ROADM cards for full add/drop flexibility. Wavelengths can be engineered to pass between rings by physically patching at the wavelength level. By using the Mesh/Multiring Upgrade card (available today - see data sheet below) you can prepare the network for Degree-N capability, allowing multiple rings to be connected via a single point with dynamic wavelength provisioning across the rings.

DWDM: ONS 15454 MSTP M6 TNCE and TSCE

In a ONS 15454 MSTP M6 chassy (DWDM) both Transport Node Controller (TNC) and Transport Shelf Controller (TSC) cards can be installed in slot 1and 8 to perform system initialization, provisioning, alarm reporting, maintenance and diagnostics.
Can someboby clarify the following:
1) What is the difference between a TNCE and TSCE Card? (The only difference I found is that TNCE can be configured with one or two SFP ports to provide the OSC termination while TSCE not. Are there other differences? )
2) Is it possible to intall in the same 15454 M6 chassy one TNCE and one TSCE card?
3) Are there any circumstance under which is mandatory to install the TNCE card?
4) Is there any suggested cisco documentation or book explaining it in details?
Thanks

You can use an Mutiple M6 chassis in one node in a Multi Shelf configuration the TNC cards are designed to go in the the Primary or 1st node and you can use the TSC cards in the other nodes and connect them together using the MSM ports on the ECU cards.
Yes your are correct regarding the OSC ports are not enabled on the TSC cards. The TSC cards are a lower cost then the TNC cards as they are only for use with a subtended shelf.
2) Is it possible to intall in the same 15454 M6 chassis one TNCE and one TSCE card?
I dont believe so however you can install just a single TNCE card in a chassis if you don't require redundancy
3) Are there any circumstance under which is mandatory to install the TNCE card?
I believe a TNCE card is required for any node in a standalone configuration or in a Multi Shelf configuration.

ONS 15454 MSTP Client Connection Options

Hi!
Have questions regarding client connection options to ONS 15454 MSTP. FYI, I have experience on ONS 15540 ESPx and I usually connect client to the ONS using transponder like this
ONS 15540 ESPx
Client<->transponder<->OADM<->OADM<->transponder<->client
I am new to ONS 15454 MSTP and from the reference manual I understand that the it can be configured as hub, passive oadm, anti ase etc. My questions is how does the client get connected to each of this configurations
For example, for a passive or amplified nodes the client connections would be like this
ONS 15454 MSTP
client<->transponder<->OADM<->OA<->OA<->OADM<->transponder<->client
What about hub nodes where mux/demux card are used, where does the client connect,I do understand that these cards have to be used in pairs.
As always,appreciate your expert opinions and if you can point me to a web link that would be even better. Many Thanks.

In both cases, the client (assuming it has a non-ITU output) will connect via a transponder or muxponder card. This takes the client signal and converts (with multiplexing in the muxponder case) the client signal into an ITU wavelength.
On the MSTP, the ITU port on the transponder/muxponder is then physically patched into the appropriate port on either ROADM, OADM or Mux/Demux cards.
To directly answer your question, on a hub node equipped with Mux/Demux cards, the Tx from the Transponder is connected to the Mux card, and the Rx connected to the Demux. Likewise, at the node where the wavelength is dropped (eg at an OADM site), there will be an equivalent transpoder connected to the OADM module (Tx and Rx at wavelength xyz).
The transponders/muxponders may be in the same shelf, separate shelves, or you may use a direct ITU connection from devices such as a DWDM GBIC, an SDH DWDM card or 10GE XENPAK from Catalyst 6500.
As long as you have designed the network to take the appropriate interface types into account, you should be fine.

ONS 15454 MSTP & SNMP for MRTG

I can't find regular oid for optical power and span loss. I need them for mrtg statistics.

I have not found an SNMP value for span loss but you may be able to calculate it as the difference between the transmit power and rceive power across a span. You may want to look at cOpticalParameterValue 1.3.6.1.4.1.3607.2.30.1.1.1.3 and cMsDwdmIfTransportPower 1.3.6.1.4.1.3607.2.40.1.2.1.3 as the base OIDs for ports on OPT-BST, OPT-PRE, and MXPP cards. So far for me the values are matching up with those presented in CTC. I'm running sw version 8.5 so things may be different if you are running a significantly different version. To see RX power I add on to the base OID... cOpticalParameterValue.%inst%.1.1 . It is similar for TX and laser bias power etc. TX power = cOpticalParameterValue.%inst%.2.1 . Bias= cOpticalParameterValue.%inst%.2.5 .
I hope this helps!

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.

ONS 15454 Recommendations
Hello Guys,
Just looking for some recommendations / best practices from experienced ONS 15454 engineers for the following questions.
Scenario:
There are 2 sites located 130 km away from one to the other and we want to provide a wan connectivity via ONS 15454.
Questions:
1. The ethernet / DWDM modules preferred
2. The typical wave length will be used -- 1550 or 1310?
3. What are the speeds supported on the modules?
4. What should be the recommended max losses / power budget for 130 km for Cisco ONS to work properly?
5. Any specific recommendations.
Thanks & Regards
Jay

1. The ethernet / DWDM modules preferred
GE_XPE, 10GE_XPE, OTU2_XP, ML cards,
CE-Series 10-Port Multirate Ethernet Card, 10DME, MXP, 10x10 there are lot of cards depends on your requirement, line rates coming from WAN device, types of module present on WAN side.
2. The typical wave length will be used -- 1550 or 1310?
depends if you looking for a SDH/SONET solution, will say 1550, if DWDM than it will be composite siganal with MUX/DMUX.
3. What are the speeds supported on the modules?
10mbps, 100Mbps, 1000Mbps, 1Gig, 10Gig, 40gig and 100Gig depends on your requirement :-)
4. What should be the recommended max losses / power budget for 130 km for Cisco ONS to work properly?
around 35dB to 39dB of span loss, looks you need amplification.
5. Any specific recommendations.
we need to discuss your requiremnets, there are lot of sloution available.

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....

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.
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.

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
