nas-ip (HWTACACS scheme view)

Use undo nas-ip to delete a source address for outgoing HWTACACS packets.
Syntax
nas-ip { ipv4-address | ipv6 ipv6-address }
undo nas-ip [ ipv6 ]
Default
The source IP address of an outgoing HWTACACS packet is the IP address configured by using the
hwtacacs nas-ip command in system view.
If the hwtacacs nas-ip command is not configured, the source IP address is the IP address of the outbound
interface.

Parameters
ipv4-address: Specifies an IPv4 address, which must be an address of the device. The IP address cannot
be 0.0.0.0, 255.255.255.255, a class D address, a class E address, or a loopback address.
ipv6 ipv6-address: Specifies an IPv6 address, which must be a unicast address of the device. The IP
address cannot be a loopback address or a link-local address.
Usage guidelines
The source IP address of HWTACACS packets that a NAS sends must match the IP address of the NAS
that is 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 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.
When you use both the nas-ip command and hwtacacs nas-ip command, the following guidelines
apply:
• The setting configured by using the nas-ip command in HWTACACS scheme view is effective only
for the HWTACACS scheme.
• The setting configured by using the hwtacacs nas-ip command in system view is effective for all
HWTACACS schemes.
• The setting in HWTACACS scheme view takes precedence over the setting in system view.
If you execute the command multiple times, the most recent configuration takes effect.
