Setting the username format and traffic statistics units
A username is usually in the format userid@isp-name, where isp-name represents the ISP domain name
of the user and is used by the device to determine which users belong to which ISP domains. However,
some HWTACACS servers do not recognize usernames that contain the user ISP domain name. You can
configure the device to remove the domain name of each username before sending the username.
The device periodically sends accounting updates to HWTACACS accounting servers to report the traffic
statistics of online users. For normal and accurate traffic statistics, make sure that the unit for data flows
and that for packets on the device are consistent with those configured on the HWTACACS servers.
Follow these guidelines when you set the username format and the traffic statistics units for an
HWTACACS scheme:
If an HWTACACS server does not support a username that carries the domain name, configure the
•
device to remove the domain name before sending the username to the server.
For level switching authentication, the user-name-format keep-original and user-name-format
•
without-domain commands produce the same results. They make sure that usernames sent to the
HWTACACS server carry no ISP domain name.
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. Specify the unit for data flows
or packets sent to the
HWTACACS servers.
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. Upon
receiving an HWTACACS packet, an HWTACACS server checks whether the source IP address of the
packet is the IP address of any managed NAS. If yes, the server processes the packet. If not, the server
drops the packet.
Usually, the source address of outgoing HWTACACS packets can be the IP address of any NAS interface
that can communicate with the HWTACACS server. In some special cases, however, you must change the
source IP address. For example, if a NAT device is present between the NAS and the HWTACACS server,
the source IP address of outgoing HWTACACS packets must be a public IP address of the NAS.
You can specify the source IP address for outgoing HWTACACS packets in HWTACACS scheme view for
a specific HWTACACS scheme, or in system view for 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.
