Hi all - I have a weird one I've been scratching my head on for a few hours now…
Basic H-REAP WLAN with switch serving DHCP. The client associates, requests an
IP, stays at the "requesting IP" for a long time, then Anyconnect eventually
says, "Limited or no connectivity". Which obviously leads me to believe DHCP
isn't working in some capacity.
Here's the strange part – the client gets an IP just fine.
1 – I see the request / reply come into the switch
*Mar 1 00:41:15.719: DHCPD: Sending DHCPOFFER to client 0124.7703.3dda.08
(10.10.12.65).
*Mar 1 00:41:15.719: DHCPD: Check for IPe on Vlan12
*Mar 1 00:41:15.719: DHCPD: creating ARP entry (10.10.12.65, 2477.033d.da08).
*Mar 1 00:41:15.719: DHCPD: unicasting BOOTREPLY to client 2477.033d.da08
(10.10.12.65)
2 – On the client laptop, "ipconfig" shows that it's IP address is 10.10.12.65
– just as what was offered by the server.
3 – From the client itself, I can ping anything both on and off subnet.
4 – Other devices can ping the client IP without issue.
5 – The switch shows it as a valid binding
Sw1#sh ip dhcp binding
IP address Client-ID/ Lease expiration Type
Hardware address
10.10.12.65 0124.7703.3dda.08 Mar 02 1993 12:41 AM Automatic
But no amount of "network repairs" or rebooting allows Anyconnect to show
anything other than "Limited or no connectivity".
And just to add to this, from this same client I can connect to another SSID
that gets DHCP from the exact same switch (just a different scope) and it comes
up perfectly. Yes, the scopes are identical other than the network.
I have no idea why Anyconnect is showing "Limited or no connectivity" even
though it has full connectivity – proven by ICMP. Thoughts?
