As a best practice to avoid HWTACACS packet loss caused by physical port errors, specify a
loopback interface address as the source IP address for outgoing HWTACACS packets.
If 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 applies only
to the HWTACACS scheme.
• The setting configured by using the hwtacacs nas-ip command in system view applies to all
HWTACACS schemes.
• The setting in HWTACACS scheme view takes precedence over the setting in system view.
You can specify a maximum of 16 source IP addresses, including the following IP addresses:
• Zero or one public-network source IPv4 address.
• Zero or one public-network source IPv6 address.
• Private-network source IP addresses.
Each VPN instance can have only one private-network source IPv4 address and one private-network
source IPv6 address.
Examples
# Specify IP address 129.10.10.1 as the source address for HWTACACS packets.
<Sysname> system-view
[Sysname] hwtacacs nas-ip 129.10.10.1
