Appendix A: Specifications
Encapsulation
When you activate RFC 1483 system mode, you can select WAN encapsulation as VC multiplexing for some sessions and LLC encapsulation for other sessions.
| PPP |
|
|
Authentication | Provides authentication of PPP sessions for security through Password and |
(PAP/CHAP) | |
Network Address | Network Address Translation (NAT) maps LAN side private IP address to the |
Translation | public IP address assigned to the 32 virtual channels (RFC 1631). You can map |
| to two private addresses to each of the 32 sessions for a total of 64 addresses. |
|
|
| Routing |
|
|
Routing Protocol | Supports RFC 1724 Routing Information Protocol (RIP and RIP Version 2). |
Encapsulation | Supports Logical Link Control (LLC) or |
Static Routes | Supports up to 32 static routes. |
Address Resolution | Supports Address Resolution Protocol (ARP) over the LAN port (RFC 826). |
|
|
| Bridging |
|
|
Bridging and Address | Implements a transparent learning bridge with a bridging table of 1024 entries. |
Learning |
|
Encapsulation | Supports Logical Link Control (LLC) or |
Spanning Tree | Provides Spanning Tree support per IEEE 802.1d. |
