2.3.4 Setting the RADIUS Packet Encryption Key
RADIUS client (switch) and RADIUS server use MD5 algorithm to encrypt the
exchanged packets. The two ends verify the packet through setting the encryption key.
Only when the keys are identical can both ends to accept the packets from each other
end and give response.
You can use the following commands to set the encryption key for RADIUS packets.
Perform the following configurations in RADIUS scheme view.
Table 2-23 Setting the RADIUS packet encryption key
Operation Command
Set RADIUS authentication/authorization packet
encryption key
key authentication string
Restore the default RADIUS
authentication/authorization packet encryption key.
undo key authentication
Set RADIUS accounting packet key
key accounting string
Restore the default RADIUS accounting packet key
undo key accounting
By default, the keys of RADIUS authentication/authorization and accounting packets
are all “huawei”.
2.3.5 Setting Retransmission Times of RADIUS Request Packet
Since RADIUS protocol uses UDP packet to carry the data, the communication process
is not reliable. If the RADIUS server has not responded NAS before timeout, NAS has
to retransmit RADIUS request packet. If it transmits more than the specified retry-times,
NAS considers the communication with the primary and secondary RADIUS servers
has been disconnected.
