Step
1. Enter system view.
2. Enter HWTACACS scheme
view.
3. Specify a VPN for the
HWTACACS scheme.
Setting the username format and traffic statistics units
A username is in the format userid@isp-name, where isp-name represents the user's ISP domain name. By
default, the ISP domain name is included in a username. If HWTACACS servers do not recognize
usernames that contain ISP domain names, you can configure the device to send usernames without
domain names to the servers.
If two or more ISP domains reference the same HWTACACS scheme, configure the HWTACACS scheme
to keep the ISP domain name in usernames for domain identification.
The device reports online user traffic statistics in accounting packets. The traffic measurement units are
configurable, but they must be the same as the traffic measurement units configured on the HWTACACS
accounting servers.
To set the username format and traffic statistics units for an HWTACACS scheme:
Step
1. Enter system view.
2. Enter HWTACACS scheme
view.
3. Set the format of usernames
sent to the HWTACACS
servers.
4. (Optional.) Set the data flow
and packet measurement
units for traffic statistics.
Specifying the source IP address for outgoing HWTACACS packets
The source IP address of HWTACACS packets that a NAS sends must match the IP address of the NAS
configured on the HWTACACS server. An HWTACACS server identifies a NAS by IP address. When the
HWTACACS server receives a packet, it checks whether the source IP address of the packet is the IP
address of a managed NAS.
If it is the IP address of a managed NAS, the server processes the packet.
•
• If it is not the IP address of a managed NAS, the server drops the packet.
To communicate with the HWTACACS server, the source address of outgoing HWTACACS packets is
typically the IP address of an egress interface on the NAS. However, in some situations, you must change
the source IP address. For example, when VRRP is configured for stateful failover, configure the virtual IP
address of the uplink VRRP group as the source IP address.
You can specify the source IP address for outgoing HWTACACS packets in HWTACACS scheme view or
in system view:
Command
system-view
hwtacacs scheme
hwtacacs-scheme-name
vpn-instance vpn-instance-name
Command

| packet { giga-packet | kilo-packet
| mega-packet | one-packet } }*
