Chapter 4 Managing the Passport 8683POS Module 63
Using the Passport 8683POS Module
Configuring routing
A POS port configured for IPCP and/or IPXCP encapsulation must be the sole
member of the VLAN. You cannot add any other port to a VLAN which already
has a POS port with IPCP and/or IPXCP encapsulation enabled. You cannot add a
POS port which is configured for IPCP and/or IPXCP encapsulation to a VLAN
which already has other ports as members.
Configuring IP routing using Device Manager
To configure the Passport 8683POS Module for IP routing using Device Manager:
1 Highlight the port.
2 Choose Edit > port.
The Port dialog box opens with the Interface tab displayed (Figure 14 on
page 56).
3 Click the POS PPP tab.
The POS PPP tab opens (Figure 16).
Note: When the Passport 8600 switch is interoperating with a Juniper
router, the POS port must have the Juniper IP address configured in the
remote IP field. This is necessary because the Juniper routers do not
provide their local IP address during PPP negotiation. The Passport 8600
switch requires the Juniper address for IPCP operations. See “config pos
ip” on page 94 for information on configuring the remote IP address.
Note also that 30-bit subnet masks may be required for certain JUNOS
releases.
