Configuring Shared Interfaces on the RSD
To configure shared interfaces on the RSD:
- Configure the physical interface using the so-fpc/pic/slot, ge-fpc/pic/slot, or xe-fpc/pic/slot statement at the [edit interfaces] hierarchy level.
- Configure Frame Relay encapsulation or VLAN tagging.
- For Frame Relay encapsulation, use the encapsulation frame-relay statement at the [edit interfaces so-fpc/pic/slot] hierarchy level.
- For VLAN tagging, use the vlan-tagging statement at one of the following hierarchy levels: [edit interfaces ge-fpc/pic/slot] or [edit interfaces xe-fpc/pic/slot].
- Configure logical interfaces under the physical interface
using the unit logical-unit-number statement
at the [edit interfaces so-fpc/pic/slot] hierarchy level, the [edit interfaces ge-fpc/pic/slot] hierarchy level, or the [edit
interfaces xe-fpc/pic/slot] hierarchy level.
Note: For Ethernet shared interfaces on the JCS 1200 platform, gratuitous-arp configuration statements are supported on the Root System Domain (RSD), but not on the Protected System Domain (PSD). These statements are configured at the [edit interfaces ge-fpc/pic/slot] hierarchy level. These statements include: gratuitous-arp-reply, no-gratuitous-arp-replay, and no-gratuitous-arp-request. Values you configure for gratuitous-arp statements on the RSD are not passed to the PSD.
- For each logical SONET interface, include the following
statements at the [edit interfaces so-fpc/pic/slot.logical-unit-number] hierarchy level:
- dlci dlci-identifier—Assigns a DLCI for the point-to-point Frame Relay connection between the RSD and the PSD.
- interface-shared-with psdn—Assigns the logical interface to a PSD.
For each logical Gigabit Ethernet interface, include the following statements at one of the following hierarchy levels: [edit interfaces ge-fpc/pic/slot.logical-unit-number] or [edit interfaces xe-fpc/pic/slot.logical-unit-number].
- vlan-id number—Binds an 802.1Q VLAN identifier tag to the logical interface.
- interface-shared-with psdn—Assigns the logical interface to a PSD.
In the following example, so-0/0/0.0 and so-0/0/0.1 belong to PSD1, whereas PSD2 owns so-0/0/0.2:
In the following example, ge-1/0/0.1 and ge-1/0/0.2 belong to PSD1, whereas PSD2 owns ge-1/0/0.3:
In the following example, xe-5/0/0.0 and xe-5/0/0.1 belong to PSD4:
