Hi, I see that 6.1.2 is out and the current EMR release is 5.3.3/4 What are the plans and timing for a 6.x EMR as I need to upgrade some devices and would like to understand what's planned  Thanks Mark ... View more

Hi, I have two routers connected via a point to point layer1 dwdm fibre link via fixed 10G DWDM optics which are based on ITU 100GHz (eg DWDM-SFP10G-61.41). This works fine with no issues. Im upgrading one router to asr9k and got DWDM-SFP10G-C for the 9k. I configured it to the wavelength required but I see that the tunables are based on 50Ghz not 100Ghz like the fixed. ASR9K#sh run controller dwdm 0/8/0/23 Tue Jul 19 13:08:20.750 CET controller dwdm0/8/0/23 wavelength 50GHz-Grid update 1535822 ASR9K#sh controllers dwdm 0/8/0/23 opti$ Tue Jul 19 13:07:41.660 CET Optics Status Optics Type: 10GBASE-TUNABLE Wavelength Info: C-Band, MSA ITU Channel=19, Frequency=195.20THz, Wavelength=1535.822nm Wavelength Owner: Configuration, ITU Channel: GMPLS Signaled=None, Configured=19, Hardware Default=84 TX Power = 0.00 dBm RX Power = -40.00 dBm Question: Is it a correct and supported configuration for a link between two routers having a fixed 100Ghz dwdm optic on one side and a tunable 50Ghz dwdm on the other end of the link. Note dwdm filters in the field are also based on 100Ghz thanks Mark ... View more

Hi I need some help to clarify my understanding about two items on ASR9k. Platform is ASR9904 RSP400 running 5.3.3 I have traffic on the interface below as vlan tagged or untagged for which I want to setup l2vpn xconnect to another port (G1/0/0/4) Is there a difference between the following two config options for the interface to achieve this ? interface GigabitEthernet1/0/0/0 ! interface GigabitEthernet1/0/0/0.1 l2transport encapsulation default l2vpn xconnect group XC p2p XC interface GigabitEthernet1/0/0/0.1 interface GigabitEthernet1/0/0/4 or interface GigabitEthernet1/0/0/0 l2transport l2vpn xconnect group XC p2p XC interface GigabitEthernet1/0/0/0 interface GigabitEthernet1/0/0/4 Second question is: I classify vlan tagged traffic ingress to GigabitEthernet100/0/0/2 on subinterfaces (see below) to be able to setup different services over the physical link connected to GigabitEthernet100/0/0/2 (typically coming from a customer) One such service is internet access on vlan 10 To set this up, both of the below configs work, but Im trying to understand the best option to use. Im not sure if with option #2 (without bridge domain) I should be concerned about the other end of the link being connected to a large L2 domain with too many MAC addresses for the 9k to learn and the possibility of a broadcast storm etc.., as opposed to option #1 which is limited in terms of MACs and has storm control enabled. option#1 interface GigabitEthernet100/0/0/2.10 l2transport encapsulation dot1q 10 rewrite ingress tag pop 1 symmetric service-policy input 100M service-policy output 100M l2vpn bridge group INTERNET bridge-domain INTERNET storm-control multicast kbps 1000 storm-control broadcast kbps 1000 interface GigabitEthernet100/0/0/2.10 mac limit maximum 35 action no-flood ! secure logging ! ! split-horizon group ! routed interface BVI10 interface BVI10 ipv4 address 192.168.0.1/28 or option#2 interface GigabitEthernet100/0/0/2.10 encapsulation dot1q 10 ipv4 address 192.168.0.1/28 service-policy input 100M service-policy output 100M Thanks for your help Mark ...

Hi, Im getting a little confused with MPO cables, polarity, gender, key up,.key down etc.. I need to connect a CPAK 100GBASE-SR10 on ASR9k to a NCS panel NCS-PP-100x10-SR basically to breakout the CPAK to 10 x 10GE SR ports via the NCS panel From datasheets  and on inspection of the ports its clear that the ports are male (with pins) therefore the patch cord needs to be female. The confusing part is the polarity. I believe polarity A is required since a straight connection between CPAK and NCS PP is needed as the fibre patch cord from the PP to the 10G port on the router connecting to the CPAK swaps A and B ports as any standard fibre patch cord would do. Polarity A specifies KEY UP on one side and KEY DOWN on the other if I get this right, however again inspecting the ports on CPAK and NCS panel seem to have a KEY UP on either side, implying a  polarity  B MPO cable not polarity A, hence the confusion. Would be great if anyone can demystify :) thanks Mark ... View more
