Hi All,
Thought I would post this as I had difficulty getting info about this topic from the interweb...so its not really a question but an answer before there is a question
So sometimes your 6880's boot image might corrupt and you only get into rommon mode and nothing else.
The procedure is quite simple...
You need a PC with some tftp daemon and a healthy boot image.
Lets assume you have the following info:
example with following info:
Switch mgmt0 ip address=10.1.1.10
Mask for that LAN=255.255.255.0
Default gateway for that LAN=10.1.1.1
PC with TFTP server=10.1.1.100
Imagefilename=c6880x-adventerprisek9-mz.SPA.152-1.SY1a.bin
So, once in rommon you need to do the following (type exactly as below):
rommon B1> IP_ADDRESS=10.1.1.10
rommon B2> IP_SUBNET_MASK=255.255.255.0
rommon B3> DEFAULT_GATEWAY=10.1.1.1
rommon B4> TFTP_SERVER=10.1.1.100
rommon B5> TFTP_FILE=c6880x-adventerprisek9-mz.SPA.152-1.SY1a.bin
---->>>>you need the default gateway even if you are on same VLAN...believe me...try it
---->>>>then to check the settings type "set" which will show something like below
rommon B6> set
PS1=rommon ! >
TFTP_SERVER=172.23.16.81
IP_ADDRESS=172.29.52.71
IP_SUBNET_MASK=255.255.255.0
DEFAULT_GATEWAY=172.29.52.1
TFTP_SERVER=10.1.1.100
TFTP_FILE=c6880x-adventerprisek9-mz.SPA.152-1.SY1a.bin
TURBOBOOT=
BOOT_DEV_SEQ_CONF=disk0:;disk1:
MIRROR_ENABLE=Y
?=0
---->>>>then if you are happy with your setting try to boot via tftp with below command:
rommon B7> boot tftp://10.1.1.100/c6880x-adventerprisek9-mz.SPA.152-1.SY1a.bin
----->>>>>The tftp download should now start and you should be on the way to recovery
-----end-----
Other notes:
Make sure the confreg is correct and not set to boot into rommon...
the 6880's do not have the 'tftpdnld' command as per the other rommon devices...
Hope this helps and please correct me if I am wrong somewhere...I did this early this morning and might have missed something...
Ciao
