Step
Setting the username format and traffic statistics units
A username is in the userid@isp-name format, where the isp-name argument 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 use 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 the source IP address of the packet is the IP address of a managed NAS, the server
processes the packet.
•
If the source IP address of the packet 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.
•
The IP address specified in HWTACACS scheme view applies to one HWTACACS scheme.
•
The IP address specified in system view applies to all HWTACACS schemes whose servers are
in a VPN or the public network.
Before sending an HWTACACS packet, the NAS selects a source IP address in the following order:
1. The source IP address specified for the HWTACACS scheme.
