[PolarPanda]

Hi there,

         I want to send syslog of stack switch to syslog server, so I excuted command "logging server hostname". Here is error message I got: %ERROR: Standby doesn't support this command. I'm able to ping the hostname. Can anyone tell me how to fix the problem? Thank you!!

Can you give us more information what is this device.

can you post

show verison

show switch

need to check where you are issue this command is standby, to confirm we need to know the above details.

we have many 3850 running with below command :

logging host 10.10.10.10  <-- this is syslog server IP

make sure you are logging using SSH right ? (not on the console - if the console are you sure this is connected to Active switch - master in the stack)

Hi BB,

            yes, i used SSH. I have no problem to type in ip address like you showed me, but I have error message when typing in hostname.

Hi @PolarPanda ,

Try this:

logging host server hostname

Thank you Luis. I did try the command earlier, but I still have the same result.

Hi @PolarPanda ,

The command must be entered on the active switch.
Can you verify this?

logging server hostname

or

logging host server hostname

I think the error message tells you this:

 %ERROR: Standby doesn't support this command

Hi Luis,

          I believe I connect to the active switch. Correct me if I'm wrong. I ssh in the switch with a ip address in management vlan. The only interface management vlan configured is active switch interface.

Hi @PolarPanda ,

Apparently, it's not like that:

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3750x_3560x/software/release/12-2_55_se/configuration/guide/3750xscg/swstack.html#60650

Connectivity to the Switch Stack Through an IP Address

The switch stack is managed through a single IP address. The IP address is a system-level setting and is not specific to the stack master or to any other stack member. 

I suggest, if possible, connect via console cable to the active switch and try the mentioned commands.

Thank you Luis! I think I will stay with entering ip address instead of hostname since I have lots of more switches in different locations.
