I have a 2921 gateway that was given to me, i logged into the ip, 172.27.199.1 and clicked on SHUT DOWN, i thought it would power off the gateway but it didnt, so physically powered it off, I was connected directly via ETH, on the 172 subnet.
Now i can no longer access anything on the gateway, i get an error when i try to ping it , HOST IS DOWN. also had NO ROUTE TO HOST..
how do turn the gateway services back on? i am on a mac, so i dont have access to a serial adapter.
We are not sure what is the configuration on the switches.
If your MACbook is in same network as (172.27.199.X) and you able to ping 172.27.199.1, then you can do rest config check by ssh/telnet login to device ? if you are not able to reach the network ip 172.27.199.1, then you need get an console cable and connect to device and have look,
there is no other option i can think for now on top of my head
I am connected via usb , i have telnet into the router,
i have logged in via CLI,
can you please let me know what command to input to get the router back up?
You probably shutdown the interface that has the IP address you mentioned (172.27.199.1 ), you need to get into that interface and write the "no shutdown" command.
can you do a show ip interface brief and show us the output of that command? if it shows the interface on admin down status then it's shutdown. If for example it's the interface GigabitEthernet0/0 then you can do this:
then you will see on the logs when the interface goes up
