SSH is working very slow during base build

[gurbinder.kabbay]

Hi Experts

I am doing the base build of switches in stack  C9200L048T-4x. SW : 17.06.03.

I am configuring the basic ssh to build switches and problem is : when i accessing this switch through other switch locally then login response and running the command on switch is fast. when i am accessing the switched through WAN then response to switch in terms of accessing and running the commands on it is very slow.

below is basic config (XXXX is placeholder) which i applied on it. Moreover, the same config is working fine on other new switches , only problem with this particular switch.

no aaa-model
enable secret XXXXXX

username XXXXX password YYYYY

ip domein name XXXXXXX

ip ssh version 2

line vty 0 4

 login local

 transport input ssh

line vty 5 15

 login local

 transport input ssh

Regards,

SSH is encrypt decrypt so if the CPU face high utilize then the SSH is slow.

thanks for your reply, but cpu utilization is very normal

CPU utilization for five seconds: 1Percent/0Percent; one minute: 1Percent; five minutes: 1 Percent

are you slow in SSH login or slow to enter commend ?

Hi Experts

I have been working on this since morning and did some research and fixed it.

@MHM: yes it was both during login and command run.

Solution I applied: So routing can be the one of the issues to make it slow. there was default route missed towards my core switches. After apply that now it is working normally. if anyone of you face this type of problem then please check this one thing as well.

Thanks for your support and Guidance
