Rommon recovery, interface issue

Jonn cos

Hi all experts.

I have a simple question. Lets say i have an ISR (1800,2800). IOS is corrupt and i need to upload IOS into flash. I know the procedure of tftpdnld. This process assigns the defined IP to the first interface of the router. Like in case of 1841, ip is assigned to Fastethernet 0/0. If for some reason Fa0/0 is damaged, do i have any option to manually assign this IP to Fa0/1 ?

Hello Jonn,

Yes, on 1800/2800 series, you can select the Ethernet port to be used using the FE_PORT or the GE_PORT variable in ROMMON (the GE_PORT is not available on models with Fast Ethernet ports, and vice versa).

See the following document for more information:

Best regards,

Peter

Dear Peter,

Is the same true for 2600 series routers as well ? i have searched 2600 series docs, but i dont see FE variable anywhere !!

Hello Jonn,

Unfortunately, for 2600 series, only the first LAN interface is supported. It is stated in the following document:

http://www.cisco.com/en/US/products/hw/routers/ps259/products_tech_note09186a008015bf9e.shtml

Specifically, the article says:

The ROMmon TFTP transfer works on the first LAN port only. However, for the Cisco 2612, you can choose the Token Ring or Fast Ethernet port.

Best regards,

Peter
