Slow connection%2Fno connection via Telnet on ICX6430

Hi I have several ICX6430/ICX64S08030c that once in a while have a very slow or no response at all to my telnet sessions. I can exclued IP routing issues and probably spanning-tree issues as well, since I have connectivity to other switches that are behind the one that shows the problems. Normally only a reboot of the switch helps.

 

Does anyone have had the same experiences? Is there any less invasive method to get the device back to a fully manageable situation?

 

Any hint is appreciated.

Kind regards

Mat

Never had that issue, but I would highly recommend upgrading the firmware to to 8030j

 

 

To upgrade it:

 

copy tftp flash 10.1.144.4 ICX64S08030j.bin primary

 

If the boot code is lower than Boot Version 10.1.05T310, you should upgrade it too:

 

copy tftp flash 10.1.144.4 kxz10105.bin bootrom

 

 

If this is a PoE model usually has a "P" in it like ICX6430-48P then you may as well check the firmware of it via

 

show inline power detail | begin Firmware

 

and if below 2.1.0 Build 004 then upgrade it:

inline power install-firmware stack-unit 1 tftp 10.1.2.3 icx64xx_poeplus_02.1.0.b004.fw

Anyway, beyond this for us to help you are going to need to post your configureation.

 

That said, I highly recommend you use SSH instead; it is MUCH more secure.

 

 

Basically go int Global Configureation mode and make sure to setup a username:

 

username someone password somepassword

 

crpyto key generate rsa mod 2048

 

 

Probably should make an ACL to control access, too:

 

access-list 99 permit host 10.1.2.3

access-list 99 permit 10.99.0.0 0.0.255.255

access-list 99 denay any log

 

ssh access-group 99

 

 

May as well set some parameters: 


ip ssh authentication-retries 2
ip ssh timeout 30
ip ssh idle-time 30
ip ssh scp disable
!

 

 

Anyway, please post your config and let us know.
