ICMP cache is empty

[dattsNet07]

I am trying to configure a C9300. I have the vlan100 configure with a default gateway which I can ping. However on a PC I connect to the switch, it shows connection limited. When i do ''show ip redirects'' is show the following message.''ICMP CACHE IS EMPTY'' How can i solved that in other to have land activated?

Thank you for your help

Hello,

it is unclear what you are trying to ping. What is the IP address of the PC, and what IP address are you trying to ping ? Is the C9300 configured as a layer 2 or layer 3 switch ?

[dattsNet07]

I have try to ping the default gateway ip. my switch is a L3

[dattsNet07]

I had a wrong default gateway set, i have added a new one but did not delete the other on. would this be the problem.

In other hand, shoud i assign a ip to the default vlan1 to ?
I am lost.
Please help

Hello,

I would do a:

9300#factory-reset all

and start from scratch. With the correct default gateway configured then, see if the problem persists...

Hello,

the SVI for Vlan 100 is configured on that same switch, and you are trying to ping the IP address of the Vlan 100 SVI from a PC in that same Vlan ?

Post the configuration of your switch and indicate which port the PC is connected to...

[dattsNet07]

the L3 switch is connected to a router on port 23 that i assigned and the PC is connected to a random port.
But my idea is to connect a other switch and have the PC connected to it.

To resume have: the router=>connect to the switch on port 23=> the distribution switch2 on any port=> the pc

what happen is that when i connect the PC to the switch i get network limited.

I though that creating a layer 3 swith. But when i connect the PC to the switch2 as in the resume(shown above) i have no connection at all.

as per the description below :

router=>connect to the switch on port 23=> the distribution switch2 on any port=> the pc

can you post the switch config and router config to look, is PC Set to DHCP ? what is PC IP address ?

[dattsNet07]

the PC is set to DHCP.
i will post the switch config in few minutes

You must enable routing
Example: Router(config)#ip routing

Has the l2 vlan been created for that SVI and assigned it to an access port

conf t

vlan 100

exit

Int xx
swtichport mode access
switchport access vlan 100

Sorry for the delay in responding.

I have assigned  a port to vlan1.

To the vlan have assigned the gateway. witch would be applied to vlan 100 as well, where all the other port are assigned for traffic.

What else should i do or correct in other to have my L3 switch communication to my router through the HSPR address.

Thank you

For me i still do not see much information here, can you post switch configuration?

what is VLAN I 100 IP address, what is VLAN 1 IP address here?

what is the Router IP? what is the PC IP you got and you are trying to Ping? - what device offering you DHCP IP reservation? Switch or router?

[dattsNet07]

Sorry guy for the delay, I was out for a while. Your help is really appreciated.

I have passed below the config, please add your comments. I have added a drawing of what I am trying to archive.

Thank you
