While i was doing assurance on a CE router, my assurance couldn't pass as there were thousands log messages about %SYS-4-CONFIG_RESOLVE_FAILURE: System config parse from (tftp://255.255.255.255/network-confg) failed on a Cisco 2811. You explanation and solution provided worked for me and i now managed to assure the service and everything is working like a charm. Thanks for making effort. Regards, Jacob  ... View more

Hi Inayath Not sure if i should attached this files here. The show tech contains some kind of company  info regarding the entire network of the company. Every switch in the network is dually conneted to this VSS and break out to the ISPs. So is there any way i can send this direct to you? regards, Jacob ... View more

I first upgraded to c2960s-universalk9-mz.122-58.SE2 still my Core  couldnt see the 2960 but the 2960 can see the core. I however upgraded to the latest ios c2960s-universalk9-mz.150-2.SE still same issue. I really dont know if i should log a TAC or not. Or should i reboot the core (6509)- this is a switch in production of which my manager might have issue with this solution. The strange thing is everything is working. I have very critical servers connected on this 2960 switch and traffic is flowing. The thing is everyday i do show cdp neighbour to see if all my LAN switches are still up as we dont have any NMS to manage the network. thanks in advance. Jacob ... View more

Hi Alessio I will log a change request for this. I'll then have this switch (2960) with dual connection to the two 6509 as they are in VSS mode. After that i'll port-channel just like any other switches in the network and i'll revert with the outcomes. thank you for your patience and help, much appreciated. Regards, Jacob ... View more

Everything is working normal. Like i said that users connected on this 2960 switch are working but just that its not in the 6509 cdp table if thats the word to put. ... View more
