User Based Tunneling device not responding to Ping

    Posted Jan 22, 2024 04:28 PM

    Hi Everyone,

    I have a TAC case in for this, but I thought I would put it out here as well.  

    I have a new deploy I am working on and we are using UBT for this.  It is a 9012 gateway and a 6200f switch.

    Everything is set up and good.  We are using a Clearpass to pass a LUR to the devices to connect to the Gateway using local-vlan mode. 

    UBT tunnel establishes great we are getting a good Role and getting an IP address based off of that role.  Everything LOOKS great.  Now the issue.  We can't ping the device.  We even stripped down the role to only have an allow any/any session rule and still can't hit it.  We can hit the gateway vlan IP address.  We can see the ip address in datapath users, and we can see the correct mac in the arp table of the gateway.  We do not see the mac address in the mac-address-table of the gateway though.  We do see it in the switch.

    Any help would be appreciated.

    Is it ping the only issue ? Are you sure there is no firewall blocking the ping from the end device ?
