We have Cisoc 7k in Production with below configuration: Software BIOS: version 3.1.0 kickstart: version 8.2(3) system: version 8.2(3) Hardware cisco Nexus7700 C7710 (10 Slot) Chassis ("Supervisor Module-2") VDC 5 VDCs including Admin VDC While configuring the scheduler for Daily Auto-Backup, below error is observed: (config)# scheduler schedule name DAILY_BACKUP_SCHED Error: AAA Authentication Failed, password incorrect the credentials which we are using is configured in Cisco ISE which we are using as TACACs server. Could you please suggest how to take this ahead? Can we configure the Scheduler in Non-Admin VDC only?

Hi All,
We are using the Hardware CSS501-SCM-INT where we wanted to enable the SSH and Web-Mgmt for accessing the device.
We followed the required configuration for the both the feature but without any luck.
Regarding SSH Feature, we found that the License SSH Server is required and we are having only Standard Feature Set.
MUMGFLB_SVC_CK1# sh version Version: sg0720206 (7.20 Build 206) Flash (Locked): 8.10 Build 2 Flash (Operational): 8.10 Build 2 Type: PRIMARY Licensed Cmd Set(s): Standard Feature Set
We tried to enable the Web-Mgmt as well but here at the start we are getting the Login Page for the 1st time only, but later on we are facing the Error related TLS and SSL protocols Error .
Reference link we followed are:
http://www.cisco.com/c/en/us/support/docs/application-networking-services/css-11000-series-content-services-switches/12599-csslicensing.html
http://www.cisco.com/c/en/us/support/docs/application-networking-services/css-11500-series-content-services-switches/26202-css11000-mgt.html
Expecting a Suggestion on the same.
Regards,
YSR!!!

Hi, Thanks for the Information but still we have couple of doubts: What do you mean by New WLC, is it Primary WLC? What does AP Count mean here? Are you considering "Fail-over scenario where WLC restarts" or considering the "Fail-over scenario where WLC is having Hardware Problem and need to be replaced". We have gone through the Cisco Document and because of these doubts, our implementation has been stuck. Regards, YSR.

Hi Team, We have received HA SKU WLC 5508 with no License. As per Cisco Documentation, by default HA SKU Standby WLC will be working as an Redundant WLC instead of Load-Balancing + Redundant WLC. During the Primary WLC failure, the Standby WLC will retain its Role and here, the 90 Days timer will start. Now, our doubt is, once the Primary WLC is up, what will happen to 90 Days Timer, will it reset? Regards, YSR

No, we didnt face Bootflash memory problem. Can you check the size of the Bootflash using sh file system command? Need to make sure that the Image is present in Bootflash. Hoping that IOS is stored in Bootflash not in disk.

Hi Rizwan, Here, as per observation, Software is unable to recover these error messages (As the HW Index and ErrAddress in these errors are common) or SUP Engine is having Hardware problem (Since the Errors are collected on Active SUP Engine only). We have to isolate this issue by below method. Remove the SUP & Reinsert it again / if you have spare SUP then replace Active SUP Engin If same errors observed, we need to upgrade the Image & if not then need to replace the SUP Engine. In our case, issue got resolved after removing and reinserting the SUP Engine. CPU was normal too. Additionally, you can enable Bootup level complete, so that HW issue of Active SUP can be tackled during Bootup only & then you can remove the Active SUP Engine. Regards, YSR.

Hi Umesh, Thanks for the reply with all details. Topology of the solution which was approved is given below: 1) Every Branc is having Primary Connection to Primary SP via EBGP towards HUB Location. 2) At one of the Branch, additional Aggregator Router has been added just to terminate the Secondary Link from the Rest of the Branches via IBGP. This Aggregator Router will have EBGP with Secondary SP and thus if any Primary link fails, only Secondary SP can be utilized without much manipulation. The Secondary Links on all the branches would be on Wireless...UBR concept. By using the earlier Design I was actually trying to reduce the cost of additional aggregator Router which was used in approved design. Earlier design was rejected due to below reasons: 1) Client dont want any of their branch to become Transit Branch for Other branches. 2) There might be issue with Crypto, RRI which they are using. Excuse for the delay reply since I was not keeping well. Once again, thanks for reply. Regards, Yogesh.

Hi Sindhu, Thanks a lot for the detailed analysis. I think after applying AS path Prepend, R6 will always prefer the Secondary SP path to reach R3 or R4. If the Primary link to SP is up for both R3 & R4, reverse traffic from R6 should be via R1. which isn't happening in your Config. R1 & R2 are SP in live environment, so we can't make change in those Routers. Thanks, Yogesh

Hi Umesh, Its correct, R1 & R2 are SP Routers & I don't have access to those. We are just advertising LoopBacks to SP from Hub & Branch Side. One way I am thinking is Tracking of routes. We have advertised Default Route from Hub. At branch we are tracking it & set the Primary SP on the basis of that since it received from the SPs. E.g. Branch 2: route-map Nonexist permit 10 match ip address 20 match as-path 20 neighbor 20.1.1.5 advertise-map Loopback non-exist-map Nonexist route-map Loopback permit 10 match ip address 35 access-list 35 permit 2.2.2.2 access-list 35 deny any access-list 20 permit 0.0.0.0 access-list 20 deny any ip as-path access-list 20 permit ^1 Thinking of applying same logic on R5 router & tweaking it as per requirement. - Yogesh

Dear All, Please find the below attached Topology: R3,R4 & R5 are directly connected to R1 as a Primary Service Provider to reach the Router R6. All are connected via EBGP and advertising only Loopbacks. So primary path to reach the Loopback of R6 is via R1 i.e. Primary SP. Primary Path: R3/R4/R5-----------------------------R1------------------------------------------R6 EBGP EBGP R2 is Secondary SP to reach the Loopback of R6. Branch R3, R4 are connected to R5 via IBGP and R5 is having EBGP neighborship with R2. Means to R3 & R4 to reach the Loopback of R6 should divert via R5. R5 is acting as Next-hope for R3 & R4. If Primary of R3 or R4 is Down & R5 Primary link is up: R3/R4-------------R5--------------------R2-------------------------R6 IBGP EBGP EBGP R5-----------------------------R1------------------------------------------R6 EBGP EBGP Our Requirement is: 1) The traffic of R5 should divert via Primary SP i.e. R1 even if Prmairy link of R3/R4 is down. If its primary links goes down then R5 should take path from R2. 2) If Primary Link of R3/R4 towards SP1 is down then the traffic of R3 & R4 should divert via Secondary SP i.e. R2. In this case, the Primary link of R5 is till up so the Loopback of R5 should be reachble via SP1 the Loopback of R3/R4 should be reachable via R2. Problem we are facing: 1) Since the R5 has been configured to divert the traffic via R1, & if R3/R4's primary link is down then all traffic forwarded to R1. which we dont want. Traffic flow should be If primary link is up R3/R4-------------R1--------------------R6 R5------------------R1--------------------R6 If Primary link of only R3/R4 is down then R5------------------R1--------------------R6 R3/R4-------------R5--------------------R2-------------------------R6 2) Reverse traffic from R6 should follow the same path to keep the routing Symmetric. 3) Since R6 is HUB location, so we cant to do much changes over there. Can anybody help us out to solve this issue. Regards, YSR.
