Kerberos does not provide any service for un-authentication or logout. Kerberos does provide a ticket lifetime, but that value is encrypted and cannot be detected during snooping. To enable the aging and removal of snooped Kerberos entries, this timer defines the maximum age for a snooped entry. When a MAC address with a corresponding Kerberos entry in identity manager is aged out, the Kerberos snooping aging timer starts. If the MAC address becomes active before the Kerberos snooping aging timer expires, the timer is reset and the Kerberos entry remains active. If the MAC address is inactive when the Kerberos snooping aging timer expires, the Kerberos entry is removed.
NoteThe default value for this command is none, which means that an identity discovered through Kerberos snooping is removed immediately on the aging out of the identity MAC address by the FDB manager.
