Can not see running-config.
When I issued "show running" it just gave me another prompt line...
I've heard that it could happen if it is not enough memory, but in my cast it seems OK.
It is 3640 router with c3640-ds-mz.121-5.T9.bin
There is no special privileges configureg. I am at level 15 enable mode.
Below is what I got on the telnet session.
UL#sh proc mem
Total: 12941600, Used: 11014684, Free: 1926916
UL#sh proc cpu
CPU utilization for five seconds: 4%/3%; one minute: 7%; five minutes: 7%
He was typing sh run ...... he may need to type sh config ...
It depends on the IOS.
If he types show ? it might lead him in the right direction.
Someone recently posted that privilege levels can cause this. You may have the required privileges to see the startup config, but not the running config.
Were you able to see the running config before properly ??
Did this "phenomenon" start just, one fine day ??
Did you try reloading the router and see if it works ?
I do not know when it started. I just bumped into it.
And I did not reboot router yet. It is production router so I can not do it.
Can somebody from Cisco give us some comments?
As in another similar post...on the same forum, the problem was cleared up after a reload. I would advise, to schedule a downtime, and reload the router.
If any extra commands have been added, try giving a write memory (which I guess should be working without any problem) and then give a reload.
Running configs are not displayed USUALLY due to memory shortages.
Hope that helps!
I had similar problem thought was related to upgrade i did and sho run will not show a thing but show config shows it. I checked the log and see memory problems........ and after downgrading to former IOS the memory problem cleared and and can run "show run" again.
So try relaod to clear the mem and see.
It is c3640 running c3640-is-mz_120-9.bin and it has 8Mb of flash.
I upgrade to c3640-is-mz_120-27.bin but did not help and have to downgrade to c3640-is-mz_120-9.bin. The problem is still there
Also the tech case i opened shows that Virus is affecting the network.
check the output of 'show ip cache' and if you find any entry for foreign host that indicates that the network is infected by the worm and you can setup a sniffer to determine the source and isolate the affected host/segment.
