Cisco Config Problem

[jonks]

I have a Cisco 2500. I am having trouble when i come to save a new config. The config saves ok using WRITE MEM or COPY RUNNING-CONFIG STARTUP-CONFIG. Hoever when i reload the router the config disappears.

Can someone let me know how to solve this issue. Thanks in advance.

it sounds like your config-register is set incorrectly. Log into the router and do a "show version".

"output of end of sh ver command "
FastEthernet/IEEE 802.3 interf
2 Serial network interface(s)
32K bytes of non-volatile config
8192K bytes of processor board S

**********Configuration register is 0x2102***************8

It will tell you the config-register value in hex. If it is anything other than 0x2102, try setting it to 0x2102 from Priv. Exec. mode by typing

Router>en <CR>
Password:******

Router#conf t <CR>
Router(config)#config-register 0x2102 <CR>
Router(config)# <ctrl+z>
Router#reload <CR>
Confirm RELOAD <CR>


this will tell the router to use the config you wrote with the copy run start command or wr mem command.


Hope this gets you going.
