Chapter 8: Basic Configuration Examples
Auth (Authenticated)—The SmartPath AP has been authenticated and can now exchange data traffic. You can also
check the presence of cluster neighbors by viewing the entries listed in the Supplicant column for the wifi1.1 interface in
the output of the show auth command.
If the SmartPath AP does not have any network settings, check that it can reach the DHCP server. To check if a DHCP
server is accessible, enter interface mgt0 dhcp-probe vlan-range <number1> <number2>, in which <number1> and
<number2> indicate the range of VLAN IDs on which you want the SmartPath AP to probe for DHCP servers. The results
of this probe indicate if a DHCP server is present and has responded. If the probe succeeds, check the DHCP server for
MAC address filters or any other settings that might interfere with delivery of network settings to the SmartPath AP.
• Are the SmartPath APs in the same subnet as SmartPath EMS?
SmartPath APs must be in the same subnet and the same VLAN as SmartPath EMS for their broadcast CAPWAP Discovery mes-
sages to reach it. If you can move the SmartPath APs or SmartPath EMS so that they are all in the same subnet, do so. If they
must be in different subnets from each other, it is still possible for the SmartPath APs to contact SmartPath EMS, but not by
broadcasting CAPWAP messages. For a list of other connection options, see "How SmartPath APs Connect to SmartPath EMS"
on the next page.
• Can the SmartPath APs ping the IP address of the SmartPath EMS MGT interface?
Enter the ping <ip_addr> command on the SmartPath AP, where the variable <ip_addr> is the IP address of the SmartPath EMS
MGT interface. If it does not elicit any ICMP echo replies from SmartPath EMS, make sure that SmartPath EMS is connected to
the network through its MGT interface, not its LAN interface, and that the IP address settings for the MGT interface are accu-
rate (see SP Admin > SmartPath EMS Settings > Interface Settings in the SmartPath EMS GUI).
• What is the status of the CAPWAP client running on the SmartPath AP?
To check the CAPWAP status of a SmartPath AP, enter the show capwap client command. Compare the "RUN state" with the
CAPWAP states explained in Figure 8-5. Check that the SmartPath AP has an IP address for itself and the correct address for
SmartPath EMS. If for some reason, the SmartPath AP does not have the correct address for SmartPath EMS, you can set it
manually by entering the capwap client server name <ip_addr> command, in which <ip_addr> is the SmartPath EMS MGT
interface IP address.
When SmartPath APs have contacted SmartPath EMS, they appear in the Monitor > Access Points > SmartPath APs page, as
shown in Figure 8-6.
