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 Guys,
Thank you to all of you who had offered me help to solve my issue. I have found a solution. After some change in my routing table and modification in my firewall, everything came up smoothly.
Once again thank you, see you in the next issue.

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 ?

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...

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.

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?
