Terminal Monitor issue with WS-C4503-E

[Ayub]

I am facing issue with WS-C4503-E switch. When i am trying to log in by telnet to switch then i am not getting links up and down messages although i enabled terminal monioter and logging synchronous etc but still out of result.

Hi

My undestanding is you want to see logs, is that correct? Try to configure

logging on

logging buffered 5
logging trap 5

terminal monitor should display the logs on the screen.

Thanks Julio for reply but no luck.

Hi

Try configuring under the interfaces:

interface range <interfaces range>

logging events link-status

If im not wrong, it is different config compared with other switches.

Hope it is useful

:-)

Yeah Julio it start working but when i am going for #show logging. Is there any way to get link status message without going for #show logging ?

Hi

Try configuring:

logging monitor 6 

and 

line vty 0 15

logging synchronous all

Hi

Can you please share the output for this command:

show terminal | include Capa

you should see something like:

Thank you in advance.

Hi,

Apparently show terminal has not been enabled 

#show terminal | include Capa
Capabilities: none

Please try again enabling it and verify again the output.

switch# terminal monitor

[Ayub]

Thanks Julio for all the help. It start working now but can you please identify which of the below command did the spark for me because #terminal monitor i have use it before but at that time it didn't work for me. so i am confused because i have more then 40 switches with the same issue. what should be my approach (command).


SW#terminal monitor
SW#show terminal | include Capa
Capabilities: Receives Logging Output

49w0d: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet2/6, changed state to down
49w0d: %LINK-3-UPDOWN: Interface GigabitEthernet2/6, changed state to down
49w0d: %LINK-3-UPDOWN: Interface GigabitEthernet2/6, changed state to up
49w0d: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet2/6, changed state to up

(1) - logging on
logging buffered 5
logging trap 5
(2) - interface range <interfaces range>
logging events link-status
(3) - Try configuring:
logging monitor 6
and
line vty 0 15
logging synchronous all
(4) - switch# terminal monitor

[Ayub]

One more thing, when i am log out and then log in by line vty and any link goes down it not showing me link up and down status until i enable terminal monitor.
