LAN
This section describes the process to configure the port, VLAN, LLDP, IPv4, and IPv6 settings on the WAP device.
IPv4 Configuration
Use the IPv4 Configuration section to configure the IPv4 address.
Procedure
Step 1 |
Select LAN > IPv4 Configuration. |
Step 2 |
Configure the following IPv4 settings:
|
Step 3 |
Click Apply to save the changes. |
DHCP Auto Configuration Settings
-
DHCP Auto Configuration Options— This option is enabled by default. When AP comes up with factory defaults, it first tries to auto configure using DHCP options.
During Auto Configuration:
-
AP boots up with only Ethernet interface enabled and WLAN interfaces down.
-
No services are available to User (except User Interfaces).
-
DHCP Auto Configuration Options is disabled automatically after Wait Interval or TFTP upload of Configuration file whichever is earlier.
-
Disabling the DHCP client (i.e., configure use a static IP address) or disabling DHCP Auto Configuration Options immediately aborts Auto configuration.
DHCP client automatically broadcasts requests for DHCP options 66 and 67. If DHCP and DHCP Auto Configuration Options are enabled, Access Point is Auto configured during next reboot considering the information received from DHCP Server for DHCP requests.
-
Note |
Configuration upload operation by User/Cisco overrides the Auto Configuration so that the chosen configuration file is given preference. In any other cases of rebooting the AP such as firmware upgrade or reboot operations, existing Auto Configuration settings will be effective. |
-
TFTP Server IPv4 Address/Host Name—If you configure TFTP server address, it is used in case of failure to retrieve file from other TFTP Servers specified by DHCP server during Auto Configuration. Enter IPv4 address or hostname information. If it happens to be in hostname format DNS server must be available to translate hostname into IP address.
The value is used during the Auto Configuration procedure during next boot-up.
-
Configuration File Name—If you specify the configuration file name, it is retrieved from TFTP Server during Auto Configuration of AP, in case the boot file name is not received from DHCP server. Absence of this value indicates config.xml to be used. The file must have an xml extension if specified.
The value is used during the Auto Configuration procedure during next boot-up.
-
Wait Interval—If configured, Access Point comes up with the local configuration and makes enabled services available to the user, after the wait interval. Access point aborts Auto configuration if TFTP transaction is not initiated within this interval specified. The default value is 3 minutes.
The value is used during the Auto Configuration procedure during next boot-up.
-
Status Log—This field displays reason of Auto Configuration completion or abort.
IPv6 Configuration
Use the IPv6 Configuration section to configure the IPv6 address by performing the following steps:
Procedure
Step 1 |
Select LAN > IPv6 Configuration. |
Step 2 |
Configure the following parameters:
|
Port Settings
Use the Port Settings Table to view and configure the settings for the port that connects the WAP device to a LAN.
Procedure
Step 1 |
Select .The Port Settings Table displays the following status and configurations for the LAN interface:
|
||
Step 2 |
Click Apply. |
Spanning Tree Protocol
In the Spanning Tree Protocol mode, the Enable checkbox is checked by default to enable the STP mode on the Cisco WAP device. When enabled, STP helps prevent switching loops. STP is recommended if you configure the WDS links.
VLANs Setting
Use the VLAN Configuration page to view and configure the VLANs settings.
Procedure
Step 1 |
Select LAN > More > VLANs Setting Table. |
Step 2 |
Configure these parameters:
|
Step 3 |
Click Apply. The changes are saved to the Startup Configuration. |
Neighbor Discover
Bonjour enables the WAP device and its services to be discovered by using multicast DNS (mDNS). Bonjour advertises services to the network and answers queries for the service types that it supports, simplifying network configuration in your environments.
The WAP device advertises these service types:
-
Cisco-specific device description (csco-sb) — This service enables clients to discover the Cisco WAP devices and other products deployed in your networks.
-
Management user interfaces — This service identifies the management interfaces available on the WAP device (HTTP and SNMP).
When a Bonjour-enabled WAP device is attached to a network, any Bonjour client can discover and get access to the configuration utility without prior configuration.
A system administrator can use an installed Internet browser plug-in to discover the WAP device. The web-based Configuration Utility shows up as a tab in the browser.
Note |
The system administrator can view the Bonjour enabled WAP’s using the latest Internet Explorer plug-in (Cisco Business Dashboard tool). All WAP devices present in a cluster, are shown under the cluster name after the Bonjour discovery process. The administrator should ensure that the name of the cluster is unique within a network. |
Bonjour works in both IPv4 and IPv6.
To enable the WAP device to be discovered through Bonjour, follow these steps:
Procedure
Step 1 |
Select . |
Step 2 |
Check Enable to enable Bonjour. By default, this option is enabled. |
Step 3 |
Click Apply. The changes are saved to the Startup Configuration. |
LLDP
The Link Layer Discovery Protocol (LLDP) is defined by the IEEE 802.1AB standard and allows the UAP to advertise its system name, system capabilities, and power requirements. This information can help to identify system topology and detect bad configurations on the LAN. The AP also supports the Link Layer Discovery Protocol for the Media Endpoint Devices (LLDP-MED), which standardizes additional information elements that devices can pass to each other to improve network management.
Procedure
Step 1 |
To configure the LLDP settings, select . |
Step 2 |
Configure the following parameters:
|
Step 3 |
Click Apply. |
IPv6 Tunnel
The WAP device supports the Intra-Site Automatic Tunnel Addressing Protocol (ISATAP). The ISATAP enables the WAP device to transmit IPv6 packets encapsulated within the IPv4 packets over the LAN. The protocol enables the WAP device to communicate with remote IPv6-capable hosts even when the LAN that connects them does not support the IPv6.
The WAP device acts as an ISATAP client. An ISATAP-enabled host or router must reside on the LAN. The IP address or host name of the router is configured on the WAP device (by default, it is ISATAP). If configured as a host name, the WAP device communicates with a DNS server to resolve the name into one or more ISATAP router addresses. The WAP device then sends solicit messages to the routers. When an ISATAP-enabled router replies with an advertisement message, the WAP device and the router establish the tunnel. The tunnel interface is assigned a link-local and a global IPv6 address, which serve as virtual IPv6 interfaces on the IPv4 network.
When IPv6 hosts initiate the communication with the WAP device connected through the ISATAP router, the IPv6 packets are encapsulated into IPv4 packets by the ISATAP router.
-
ISATAP Status — Check Enable to enable ISATAP on the device. By default, this option is enabled.
-
ISATAP Capable Host — Enter the IP address or DNS name of the ISATAP router. The default value is isatap.
-
ISATAP Query Interval — Enter how often the WAP device should send queries to the DNS server to attempt to resolve the ISATAP host name into an IP address. The valid range is 120 to 3600 seconds. The default value is 120 seconds.
-
ISATAP Solicitation Interval — Enter how often the WAP device should send the router solicitation messages to the ISATAP routers. The WAP device sends the router solicitation messages only when there is no active ISATAP router. The valid range is 120 to 3600 seconds. The default value is 120 seconds.
-
ISATAP IPv6 Link Local Address— The IPv6 address used by the local physical link. The link local address is not configurable and is assigned by using the IPv6 Neighbor Discovery process.
-
ISATAP IPv6 Global Address— If the WAP device has been assigned one or more IPv6 addresses automatically, the addresses are listed.
Note
When the tunnel is established, the ISATAP IPv6 Link Local Address and ISATAP IPv6 Global Address fields appear on the page. These are the virtual IPv6 interface addresses.
