Managing the Operational Link Map
To connect the Ethernet link to an external LAN, specify EXTERNAL in the command
line. The WAN bridge/router automatically associates the link with the correct external
LAN. For example, this command connects Ethernet 1 to segment B:
Xyplex>> define chassis slot link ethernet 1 segment b
The software automatically connects the Ethernet link to segment B. The link map looks
like the one in Figure 3-12 after the change. This figure includes a LAN bridge/router with
an Ethernet link to segment B, which provides access to the external LAN for the Ethernet
link of the WAN bridge/router, which also connects to segment B.
