Authentication
PN: 1725-36080-001_J.doc
In addition to the encryption, Aruba recommends the use of MAC
authentication to authenticate the Spectralink handsets. On the Aruba
System, the roles for SpectraLink Wireless Telephones are derived
using MAC-authentication. The wireless telephones can be
authenticated individually using MAC-authentication or as a group
using the vendor OUI and derivation rules. For instruction on
enabling MAC-authentication refer to Aruba's user guide.
For the OUI based derivation rule, configure the following from the
CLI:
aaa derivation rules user
set role condition macaddr starts-with "00:90:7a" set-
value phone
