Step Command Remarks
4. Specify the unit for data flows
or packets sent to the
HWTACACS servers.
data-flow-format { data { byte |
giga-byte | kilo-byte | mega-byte }
| packet { giga-packet | kilo-packet
| mega-packet | one-packet } }*
Optional.
The default unit is byte for data
flows and one-packet for data
packets.
NOTE:
•
If an HWTACACS server does not support a username with 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 usernames sent to the
HWTACACS server carry no ISP domain name.
Specifying a 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 the NAS's any
interface that can communicate with the HWTACACS server. In some special scenarios, however, you
must change the source IP address. For example, if a Network Address Translation (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. If the NAS is configured with the Virtual Router
Redundancy Protocol (VRRP) for stateful failover, the source IP address of HWTACACS packets can be
the virtual IP address of the VRRP group that the uplink belongs to.
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.
Before sending an HWTACACS packet, a NAS selects a source IP address in this order:
1. The source IP address specified for the HWTACACS scheme.
2. The source IP address specified in system view.
3. The IP address of the outbound interface specified by the route.
To specify a source IP address for all HWTACACS schemes:
Step Command Remarks
1. Enter system view. system-view N/A
2. Specify a source IP
address for outgoing
HWTACACS packets. hwtacacs nas-ip ip-address
By default, the IP address of the outbound
interface is used as the source IP address.
