Managing the Operational Link Map
The Link Map for a WAN Bridge/Router 460
A WAN Bridge/Router 460 has one Ethernet link and either two or four WAN links. The
Ethernet link can connect to any one of the midplane Ethernet segments or an external
LAN. The WAN links connect to external WANs only. Figure 3-10 shows the link map
for a WAN Bridge/Router 460 with the default and optional connections.

Figure 3-10. The Default Link Map for a WAN Bridge/Router 460 with Optional
Connections
The default connections in the link map for a WAN bridge/router are Ethernet 1 Segment
A, WAN 1 External 1, WAN 2 External 2, WAN 3 External 3, and WAN 4 External 4.
Several types of modules can provide access to an external LAN for the Ethernet link.
These include a 3605 LAN interface card (LIC), a LAN bridge/router, or a concentrator
with an AUI link.
