What does the output of sh ip cef is telling you? Kindly consider copy/pasting the entire output of
term exec prompt timestamp
show int gig0/0
show ip interface gig0/0
Thanks ... Palani

Hi Carsten
Thank you for explaining how you use the setup. I see what you mean.
To confirm my understanding, for those whom you configured "max number of calls = 2", are you saying 'actionable incoming call alert' set to disabled meets their needs?
Kind regards ... Palani

Hi Carsten
Happy to help. I suggest that you look at using "Show for Invisible Incoming Call" instead of disabling. This way, the option (answer, decline, ignore) pops up only when they have 1 existing call in progress and a 2nd call comes in.
As a user, I would love this capability and I am sure your users will too.
Kind regards .... Palani

Hi Stuart
Refreshed the original post and realized you have a Nexus box. From what I am finding, you need to do either of the following:
Few more things to give it a shot: ! ip tftp source-interface Loopback0 vrf default !
The cmd reference guide does not mention anything about configurable options after interface name. So, please consider issuing
ip tftp source-interface Loopback0 ?
and share what you see.
The other possible answer is either of the following two config. These are unique to Nexus-OS implementation alone. snmp-server context TEST vrf default snmp-server community copyconfig rw snmp-server mib community-map copyconfig context TEST OR snmp-server context TEST vrf default NOTE: If you choose to go this route, then you need to specify the context along with the community string. snmpset -v 2c -c copyconfig@TEST 10.10.10.1 ccCopyEntryRowStatus.507 i 5 NOTE In all of the above, I attempted to use default as the VRF that has IP connectivity to the TFTP-Server. If the name is different, please replace

Hi Stuart
Citing below the snippet of what you observed:
A pcap take on config-server shows the tftp transaction sourced from the IP address of the interface on dc-b-rtr which is 'closest' routing-wise to config-server.
Given this, if you were to specify ip tftp source-interface where the variable is the interface name associated with the source ipAddress closest to the config-server, I expect the TFTP to be successful.
If not, that would point to a bug in your release. The MIB predates the wide-spread use of VRFs and so, I don't expect the MIB to change. Cisco's direction seem to be pointing towards using ip <controlPlanProtocolName> source-interface. These are what I observed, to suggest using an explicit ip tftp source-interface cmd.

Yes, the answer is Yes. If the 2nd PS is faulty and not functioning, the ASR is capable of functioning with the 1/good PS as long as the 2nd faulty PS is still housed in the chassis.
When time comes to swap out the faulty PS, you have 5 minutes to accomplish the swap.

Ok, Rob precisely identified that this is a "enhancement request". Typically, these are driven by business needs.
The Actionable Incoming Call Alert feature provides a way to a user to control the incoming call alerts, under the following two conditions: -one call is in progress and a 2nd call comes in -phone is idle
In its current implementation, via configuration, you have the option to: -disable -Show for all Incoming Call -Show for Invisible Incoming Call
When the “phone is idle”, ignore makes no sense. However, if you are on call 1 and call 2 comes in, the option to “Answer”, “Divert” OR “ignore” has some relevance. While “answer and divert” are self explanatory, if you choose ignore, “ringing stops but the call will still be alerting (LED flashing) in the background.” To me, purely as a user of the phone, configure “Show for Invisible Incoming Call” option makes sense. If one opts to choose "show for all incoming call", seeing the ignore and expecting ringing to stop (but LED to blink) was not part of the original spec. This is why this has been tagged as enhancement request.
For now, please set the configuration to "Show for Invisible Incoming Call". Please help me understand what is the benefit (in your deployment) of configuring "Show for Invisible Incoming Call" option.
Sincerely ... Palani

Yes, IOS will recognize the presence of 1 PS is inserted/present and will give you 5 minutes (in case you need to swap because the 2nd PS is down and it needs to be replaced). At that point, the router will turn itself off.
If the 2nf PS fails, the fans will still get power from the functioning PS and keep the circulation going, as long as the 2nd PS is physically located in the chassis.
I hope this helps ... Palani

For the ASR1002 to be functional, both PS need to be inserted. However, minimum of 1 PS need to be powered on.
You may be wondering why this requirement to have 2 PS inserted when only one is turned on. If so, the answer is because the fans which operate independent of the power supplies. Fans in both PS need to be operational for the system to get even ventilation.
I hope htis helps .... Palani

The only requirement is that the power supply be installed in the chassis in order to energize the fans and maintain proper system cooling. Because all the system fans can be powered by one power supply, the second power supply unit does not have to be powered on, but must be connected.
If you remove a power supply from a system that has four power supplies that are connected and powered on, the system can run only for a maximum of five minutes before shutting down.

Unfortunately, that is not a feature implemented in the switches. For complete list of features configurable, check here
On the other hand, if what you are looking for is met with this feature, then please consider locating a router in your Guest Network. The routers are capable of housing a switch module.

One more clarification. The high-CPU you observed may very well be the victim and so, I asked if you have any info about memory usage.

Ok, we see you are running 15.2(5b)E which is part of 15.2E release tree. Based on what I had personally experienced, we have not seen the problem in 15.2#, until now.
I see the CPU use images. These are good. Are you experiencing any service impact? Being a IOS device, even if the CPU is at near 100% for extended periods of time, it should not impact any of the core services. Please don't mistake me - I am not saying it is alright. All I am saying that there may not be any immediate concerns.
Do you have any tools that track memory usage? If yes, what does the memory usage look like for the past five weeks?
At some point, to have this investigated with right level of engagement, kindly consider working with TAC.

Hi Pearson
There are two components in play: router and the server. We still don't know where the problem is, though the error message seem to indicate problem is with the router.
Kindly consider attempting a copy run scp: from a router where you are successfully archiving the config. Please ensure that the server-side parameters are the same as the ones you used from the router where copy run scp: is failing.
If this test is successful, next step involves enabling debug archive config along with capturing pkts using Wireshark. Debug would help to make progress if problem is with the router side and Wireshark is helpful when the problem is on the server side. While it may sound like lot more work, kindly consider enabling the debugs and capturing Wireshark from the working setup. It helps to compare/contrast contents between working/failing routers, to get an accurate assessment of the situation.
Kind regards ... Palani
