How to shut no shut in one command

kelly.abbott — Tue, 11 Feb 2020 23:24:49 GMT

On servers and desktops we do:

C:\ipconfig /release && ipconfig /renew

That way we are able to reconnect after releasing an IP and not thrown out and unable to reconnect because it has no IP.

For the Cisco 4506e:

What is the syntax to do a shut, no shut command as one entry so when I'm thrown out, the port goes back to no shut so I can reconnect?

Depends on the age of the NIC.
I've seen wired clients that have very old NIC that "shut/no shut" does not help and the only way for the NIC to "wake up" is to reboot the entire chassis.

Hi there,

You can't chain commands like that on IOS. The best you can do is launch an EEM script and then have that execute the commands in the background:

!
event manager applet SHUTNOSHUT
event none
action 1.0 cli command "enable"
action 2.0 cli command "conf t"
action 3.0 cli command "int gi0/1"
action 4.0 cli command "shut"
action 5.0 cli commnad "no shut"
action 6.0 cli command "quit"
!

Then from the CLI launch it with:

event manager run SHUTNOSHUT

cheers,

Seb.

- Thrown out , depending on what it means, note also that a 'null-time-elapsed' shut/no-shut may not always achieve the desired result.

Hello,

you could use the terminal shell to enter multiple commands. Let's say you want to bounce interface GigabitEthernet0/0 (shut/no shut), you would enter the terminal shell and then enter the line below:

4506#term shell

4506#conf t; interface GigabitEthernet 0/0; shut; sleep 5; no shut; end

you can do it using EEM and it should give you desired results.
