This table contains all entries of the PMK caches.

Telnet path:

Status > WLAN > PMK-Caching > Content

Authenticator

This entry contains the MAC address of the authenticating access points.

Supplicant

This entry contains the MAC address of the authenticating WLAN client.

Source

This entry indicates how the WLAN client obtained the PMK:

• Unknown: The source is unknown. This entry should not occur in normal operation.
• Authentication: PMK is the result of a normal 802.1x-authentication between WLAN client and access point.
• Pre-authentication: PMK is the result of a normal 802.1x-pre-authentication between the WLAN client and another access point.

OKC: The PMK results from opportunistic key caching.

User name

This entry contains the user name, which the RADIUS server sends to the access point for access permission.

Note: If the RADIUS server does not transmit a user name, this field is left blank.

VLAN ID

This entry contains the VLAN-ID, which the RADIUS server sends to the access point for access permission.

Note: If the RADIUS server does not transmit a VLAN-ID, this field is left blank.

Lifetime

This entry contains the lifetime of the PMKs in seconds. It is calculated from the validity of the session, which the RADIUS server transmitted with the access permission. The value is 0 seconds if the RADIUS server did not transmit a duration or the PMK does not have a validity period.

Expired

This entry shows whether a PMK has expired. If this is the case, the access point no longer accepts PMK-caching or authentication attempts with this PMK. Instead, it will launch a new 802.1x authentication.
