Router Reload

[Josiah Inubio]

Guys,

Is it issuing a command "reload" harmful to the router? I do daily router reload just to make my cellular interface be UP because its having Radio power mode = OFF.

Thanks.

Hello, reloading the router should not have any harm to the device itself. All this is doing is 'halting' the system and loading the IOS firmware again.

Here is a quote from a Cisco doc and the entire section doesn't say whether or not it has any adverse impact on the device:

Usage Guidelines
The reload command halts the system. If the system is set to restart on error, it reboots itself. Use the reload command after configuration information is entered into a file and saved to the startup configuration.

Hope this helps

You can use an EEM script to do one of two things:

1.  At a set time/date or event, you disable/enable the cellular interface; or

2.  At a set time/date, you reload the router

This is much easier if you can't reach into the router remotely.

What's EEM script? How to do it? It really is so much useful if these happens.

EEM stands for Embedded Event Manager.  Basically it's a pre-defined script.

In an example, you can say, that if at a particular-defined event (like the protocol is "down"), the script willl disable/enable the interface.  You can even say disable, wait for 5 seconds, enable.

There's an EEM sub-section and you can move this thread there.  Look at for a Cisco guy called Joe Clarke.  He's THE person to look out for in EEM-world.

The problem i'm encountering is that the cellular interface is UP but as of "sh cell 0/2/0 rad" the radio is off. That data is captured today. How am i going to do EEM script for this one? The recent event i'm getting is "Apr 25 11:17:49.881 MNL: %CELLWAN-2-MODEM_DOWN: Modem in HWIC slot 0/2 is DOWN" .

Interface                    IP-Address       OK? Method Status           Protocol

Cellular0/2/0              10.49.180.173   YES IPCP     up                    up

PHILAM-SJA-BR01#sh cell 0/2/0 rad

Radio power mode = OFF, Reason = Unknown

Current Band = None, Channel Number = 0

Current RSSI = -0 dBm

Band Selected = not selected due to invalid band mask

Yeah, your scenario is perfect for an EEM script.

Yeah, i'm making a discussion already for EEM scripting section. Hopefully they'll me with it. Thank you for your prompt advise. Appreciate it!
