Managing the Network

Setting the Management Access Interface

The Management Access Interface is the default interface for in-band management of the controller and connectivity to enterprise services. It is also used for communication between the controller and access points (APs). The management interface has the only consistently pingable in-band interface IP address on the controller. You can access the web interface of the controller by entering the management interface IP address of the controller in your browser's address bar.

For APs, the controller requires one management interface to control all inter-controller communications and one AP manager interface to control all controller-to-access point communications, regardless of the number of ports.

To enable or disable the different types of management access to the controller:

Procedure

Step 1

Choose Management > Access.

The Management Access window is displayed. The number of enabled management types are displayed at the top of the window.

Step 2

You can enable or disable the following types of management access to the controller, by choosing the appropriate option from the drop-down list:

  • HTTP Access—To enable HTTP access mode, which allows you to access the controller GUI using http://<ip-address> through a web browser, choose Enabled from the HTTP Access drop-down list. Otherwise, choose Disabled.

    The default value is Disabled.
    Note 
    HTTP access mode is not a secure connection.

  • HTTPs Access—To enable HTTPS access mode, which allows you to access the controller GUI using http://ip-address through a web browser, choose Enabled from the HTTPS Access drop-down list. Otherwise, choose Disabled.

    The default value is Enabled.
    Note 
    HTTPs access mode is a secure connection.

  • Telnet Access—To enable Telnet access mode, which allows remote access to the controller’s CLI using your laptop’s command prompt, choose Enabled from the Telnet Access drop-down list. Otherwise, choose Disabled.

    The default value is Disabled.
    Note 
    Telnet access mode is not a secure connection.

  • SSHv2 Access—To enable Secure Shell Version 2 (SSHv2) access mode, which is a more secure version of Telnet that uses data encryption and a secure channel for data transfer, choose Enabled from the SSHv2 Access drop-down list. Otherwise, choose Disabled.

    The default value is Enabled.
    Note 
    The SSHv2 access mode is a secure connection.

Setting Date and Time

The date and time on the Cisco Mobility Express controller is first set when running the initial configuration setup wizard of the controller. You can either enter the date and time manually or you can specify a Network Time Protocol (NTP) server that sets the time and date.

Using NTP Servers to Automatically Set the Date and Time

You can have up to three Network Time Protocol (NTP) servers, to which the controller can automatically sync to set the date and time.

By default three NTP servers are automatically created. The default fully qualified domain names (FQDN) of the NTP servers are:

  • 0.ciscome.pool.ntp.org, with NTP Index value 1.

  • 1.ciscome.pool.ntp.org, with NTP Index value 2.

  • 2.ciscome.pool.ntp.org, with NTP Index value 3.

You can specify the IPv4 address or the FQDN name of an NTP server during the initial configuration wizard. This will be applied to the server having NTP Index 1, thereby overwriting its default FQDN, 0.ciscome.pool.ntp.org .

For adding and editing NTP server details, go to Management > Time. This opens the Time Settings page.

Adding and Editing NTP Servers

You can have up to three Network Time Protocol (NTP) servers, using which the controller can automatically set the date and time.

Procedure
Step 1

Choose Management > Time.

The Time Settings window is displayed, with the set time zone shown at the top of the page. The current date and time are displayed in the Set Time Manually field. Existing NTP servers, if any, are listed in the order of their NTP Index values.

Step 2

In the NTP Polling Interval field, specify the polling interval, in seconds.

Step 3

To edit an existing NTP server, click its adjacent Edit icon. To add a new NTP server, click Add NTP Server.

Step 4

You can add or edit the following values for an NTP server:

  1. In the NTP Index box, specify an NTP Index value to set the priority of the NTP server. NTP Index values can be set from 1 to 3, in the order of decreasing priority. The controller will try and sync with the NTP server with the highest priority first, until the specified polling interval time runs out. If the sync is successful, the controller does not continue trying to sync with any remaining NTP servers. If the sync is unsuccessful, then the controller will try to sync with the next NTP server.

  2. In the NTP Server box, specify the IP address or the fully qualified domain name (FQDN) for the NTP server. When you specify an FQDN, a DNS lookup is done. If the lookup fails, an error will be logged in the Syslog server. The controller will continue to resolve this FQDN and errors will be logged until you change the NTP configuration or specify a valid FQDN.

Step 5

Click Apply.

Refreshing NTP Server Status

The NTP server table on the Time Settings page, displays the status of the connection to each NTP server in the NTP Status column. The status maybe one of the following:

  • Not Tried—A sync has not been attempted yet.

  • In Sync—The controller time is in sync with the NTP server.

  • Not Synched—The controller time is not in sync with the NTP server.

  • In Progress—A sync is being attempted.

Click Refresh at any time to see the updated NTP statuses.

Deleting and Disabling NTP Servers

To delete an NTP server, choose Management > Time. In the Time Settings page that is displayed, click the Delete icon adjacent the NTP server you want to delete. Click OK in the confirmation dialog, and then click Apply.

To disable setting the date and time using NTP servers, you will need to delete all configured NTP servers by following the above process.

Configuring Date and Time Manually

Procedure

Step 1

Choose Management > Time.

The Time Settings window is displayed, with the set time zone shown at the top of the page. The current date and time are displayed in the Set Time Manually field.
Note 
These fields cannot be edited if the NTP State is set to Enable.
Step 2

From the NTP State drop-down list, choose Disable.

Step 3

From the Time Zone drop-down list, choose your local time zone.

When you choose a time zone that uses Daylight Saving Time (DST), the controller automatically sets its system clock to reflect the time change when DST occurs. In the U.S., DST starts on the second Sunday in March and ends on the first Sunday in November.

Step 4

Select the Set Time Automatically from Current Location check box to set the time based on the time zone specified.

Step 5

In the Set Time Manually field:

  • Click the calendar icon and choose the month, day, and year.

  • Click the clock icon and specify the time, in hour and minutes.

The following table shows the software update methods available.

Method

Link to Method

Updating the software using HTTP

Note 
This method is possible only if your network consists of only Cisco Aironet 1830, 1850, 2800, and 3800 access points (which support ap1g4 and ap3g3 images).

See Updating the Software using HTTP.

Updating the software using TFTP

See Updating the Software using TFTP.

Updating the software directly from Cisco.com

See Updating the Software Directly from Cisco.com.

A software update ensures that both the internal controller software and the AP software on all the associated APs are updated. APs that have older Cisco Mobility Express AP software, on joining the primary AP after the software upgrade are automatically upgraded to the latest Cisco Mobility Express AP software. This is because, during the software update process, the latest Cisco Mobility Express software for all Cisco Mobility Express-supported APs that are associated with the controller is also downloaded. An AP joining the controller compares its Cisco Mobility Express software version with that on the primary AP and if a mismatch is detected, the new AP requests for a software upgrade. The primary AP facilitates the transfer of the new software from the TFTP server or the HTTP path, to the new AP.

The software download happens in the background, without impacting the network. The upgrades are automatically sequenced to ensure that the network performance is not impacted by software update.


Note

The software of up to five access points can be concurrently updated.
