NetMRI collects large quantities of low-level device data that can be viewed at any time. During troubleshooting, experienced admins can use low-level device information to help solve problems. The tool for viewing any device's diverse array of information is called the Device Viewer.

...

For devices running Aironet or Cisco IOS-based software, the page displays information about the auxiliary SSID configuration and algorithms used on the device.

Viewing Wireless Forwarding Information

The Forwarding page displays the forwarding information collected from wireless devices. The table displays the following information:

• Timestamp: The date and time when the device was queried by NetMRI.
• MAC: The MAC address of the mobile station.
• Remote IP: The observed IPv4 network address of the device.
• Remote Device: The name or ID of the device.
• Status: The status of the mobile station.
• Username: The user name of the mobile station if applicable.
• Class: The observed general 802.11 classification of the device.
• SSID: The service set identifier (SSID) provided by the mobile station.
• Vlan: The VLAN ID of the interface the client is associated with.
• Bss Device: The ID or name of the base station subsystem (BSS).

Wireless Access Points

The Hot Standby information Access Points page displays information about hot standby monitoring. The access points for wireless controllers. The table displays the following information:

• Monitored IP Address: The IP address of the monitored deviceaccess point.
• Monitored Sub Device: The ID or name of the monitored deviceidentification number of the access point.
• Name: The name assigned to the access point.
• Location: The user-specified location of the access point.
• MAC:  The The MAC address of the target unit which is being monitored.
• In Standby - If true, the current unit is in its monitoring mode which means that the unit is or will be a hot standby device.
• Status: The current status of the hot standby device.
• State: The current state of the hot standby device.
• Polling Frequency: How often the monitored target unit is being polled for health testing. The frequency value is displayed in seconds.
• Timeout: How long the monitoring unit can fail to collect information from the monitored target unit. After this time, one more failure of the polling triggers the standby unit to assume the role of the monitored unit. The timeout value is displayed in seconds.

Viewing Access Points SSIDs (Service Set Identifiers)

The SSIDs page lists the service set identifiers defined on the current wireless access point device. The SSID is a unique identifier that wireless networking devices use to establish and maintain wireless connectivity. Multiple access points on a network or subnetwork may use the same SSIDs. As an example, Cisco Aironet devices support up to 16 SSIDs and support different configuration settings for each SSID. All SSIDs are simultaneously active, depending on configuration, wireless client devices can associate to the access point using any SSID.

• Interface: Lists the interface for the device. As an example, for Cisco devices you will typically see interfaces such as Do0 for dot11radio 0. This item is also a link to the Interface Viewer.
• Auth Enabled: Shows whether authentication is required in the authentication configuration group. This field will show a value of Yes or No.
• EAP Required: Indicates whether the access point requires the Extensible Authentication Protocol to provide dynamic WEP keys to wireless devices. This field will show a value of Yes or No.
• EAP Method: If enabled, possible EAP values include Open or Shared Key authentication.
• MAC Auth Required: Indicates whether the AP uses MAC Address authentication, using the wireless client's MAC address to verify with an authentication server whether the MAC is allowed on the network. This field will show a value of Yes or No.
• MAC Auth Method: If enabled, this indicates whether EAP authentication is required for MAC address authentication or if a MAC address list is being used. An access point configured for EAP authentication forces all client devices that associate to it, to perform EAP authentication.
• Default VLAN: Cisco Aironet wireless access points use three VLANs: VLAN 2, VLAN 20, and VLAN 30. One is set as the 'native' VLAN, one as the SSID administrative VLAN, and one as the SSID guest VLAN. The value shown here is the discovered listing for the default native VLAN on the radio interface.
• Auth Algorithm: The discovered SSID authentication algorithm that is configured for each settings group.
