Hi,
I have just started messing around with cisco routers and I have run into a few things I can not found answers for.
Firstly:
I can configure a router and save the config with 'copy running-config startup-config' but when I restart the router the config is blank.
second:
sometimes I cant start a interface, in this case ethernet0. I issue the command and the interface just bounces.
wouter#show ip interface brief
Interface IP-Address OK? Method Status Protocol
FastEthernet1 unassigned YES unset administratively down down
FastEthernet2 unassigned YES unset administratively down down
FastEthernet3 unassigned YES unset administratively down down
FastEthernet4 unassigned YES unset administratively down down
Ethernet0 81.137.49.110 YES manual down down
ATM0 unassigned YES manual administratively down down
Ethernet2 unassigned YES manual administratively down down
wouter#config terminal
Enter configuration commands, one per line. End with CNTL/Z.
wouter(config)#interface ethernet0
wouter(config-if)#no shutdown
wouter(config-if)#shutdown
wouter(config-if)#
*Jan 10 04:47:32.559: %LINK-5-CHANGED: Interface Ethernet0, changed state to administratively down
wouter(config-if)#no shutdown
wouter(config-if)#
*Jan 10 04:47:48.639: %LINK-3-UPDOWN: Interface Ethernet0, changed state to up
*Jan 10 04:47:49.639: %LINEPROTO-5-UPDOWN: Line protocol on Interface Ethernet0, changed state to up
*Jan 10 04:47:54.359: %LINK-3-UPDOWN: Interface Ethernet0, changed state to down
*Jan 10 04:47:55.359: %LINEPROTO-5-UPDOWN: Line protocol on Interface Ethernet0, changed state to down
wouter(config-if)#
No idea why this is happening and I can't find any info online.
The router is a cisco 800
