It's VLAN detection. In 4.7.2 it is ARP based instead of ICMP. This causes an issue as its clearing the arp table entry for the default gw and causing anyconnect to drop.
You can either upgrade to the 4.8.0 agent or disable VLAN detect if you don't need it. -----Original Message----- From: David Wang <[email protected]> Sender: Cisco Clean Access Users and Administrators <[email protected]> Date: Mon, 29 Nov 2010 09:16:56 To: <[email protected]> Reply-To: Cisco Clean Access Users and Administrators <[email protected]> Subject: Cisco NAC Agent with AnyConnect client 2.4 or 2.5 on Mac Need some help here. We are running Cisco NAC 4.7.2 with Agent for Mac 4.7.2.507. Some users also run Cisco AnyConnect vpn client version 2.4 / 2.5. It appears the Anyconnect vpn client keeping connecting and disconnecting after some time on these Mac machines. Just wondering if anyone else having the similar issue? thanks in advance.
