H3C MSR810 - Link-Protocol Ppp; Nas-Port-Type

12
When you configure a gat eway address for a P PP address pool, follow these restrictions and
guidelines:
• If you also specify an IP address for an interface, the interface uses its own IP address to
perform IPCP negotiation.
• You can specify only one gateway address for a PPP address pool. Different PPP address
pools must have different gateway addresses (different combinations of
ip-address
and vpn-instance-name).
• You can specify any gateway address for a PPP address pool.
Examples
# Specify gateway address 1.1.1.1 and VPN instance test for PPP address pool aaa.
<Sysname> system-view
[Sysname] ip pool aaa gateway 1.1.1.1 vpn-instance test

nas-port-type
Use nas-port-type to configure the nas-port-type attribute on a VT interface.
Use undo nas-port-type to restore the default.
Syntax
nas-port-type { 802.11 | adsl-cap | adsl-dmt | async | cable | ethernet | g.3-fax | hdlc | idsl
| isdn-async-v110 | isdn-async-v120 | isdn-sync | piafs | sdsl | sync | virtual | wireless-other
| x.25 | x.75 | xdsl }
undo nas-port-type
Default
The nas-port-type attribute is determined by the service type and link type of the PPP user, as shown
in Table 5.
