2. The source IP address specified in system view for the VPN or public network, depending on where
the HWTACACS server resides.
3. The IP address of the outbound interface specified by the route.
To specify a source IP address for all HWTACACS schemes of a VPN or the public network:
Ste

Command Remarks
1. Enter system view.
system-view N/A
2. Specify a source IP address
for outgoing HWTACACS
packets.
hwtacacs nas-ip { ipv4-address |
ipv6 ipv6-address } [ vpn-instance
vpn-instance-name ]
By default, the IP address of the
HWTACACS packet outbound
interface is used as the source IP
address.
To specify a source IP address for a specific HWTACACS scheme:

Command Remarks
1. Enter system view.

2. Enter HWTACACS scheme
view.
hwtacacs scheme
hwtacacs-scheme-name
N/A
3. Specify the source IP address
of outgoing HWTACACS
packets.
nas-ip { ipv4-address | ipv6
ipv6-address }
By default, the source IP address
specified by the hwtacacs nas-ip
command in system view is used. If
the source IP address is not
specified, the IP address of the
outbound interface is used.
Setting HWTACACS timers
The device uses the following timers to control communication with an HWTACACS server:
• Server response timeout timer (response-timeout)—Defines the HWTACACS server response
timeout timer. The device starts this timer immediately after an HWTACACS authentication,
authorization, or accounting request is sent. If the device does not receive a response from the
server within the timer, it sets the server to blocked and sends the request to another HWTACACS
server.
• Real-time accounting timer (realtime-accounting)—Defines the interval at which the device sends
real-time accounting packets to the HWTACACS accounting server for online users.
• Server quiet timer (quiet)—Defines the duration to keep an unreachable server in blocked state. If
a server is not reachable, the device changes the server's status to blocked, starts this timer for the
server, and tries to communicate with another server in active state. After the server quiet timer
expires, the device changes the status of the server back to active.
The server quiet timer setting affects the status of HWTACACS servers. If the scheme includes one
primary HWTACACS server and multiple secondary HWTACACS servers, the device communicates
with the HWTACACS servers based on the following rules:
• When the primary server is in active state, the device communicates with the primary server.
• If the primary server fails, the device does the following:
{ Changes the server's status to blocked.
{ Starts a quiet timer for the server.
{ Tries to communicate with a secondary server in active state that has the highest priority.
