TX Matrix Plus Switch-Fabric Chassis Interface Names

 

TX Matrix Plus Switch-Fabric Chassis Interface Name

In certain statements and commands in the CLI, you refer to a TX Matrix Plus chassis as sfc (switch-fabric chassis). You can configure a TX Matrix Plus chassis by including statements at the [edit chassis] hierarchy level. To display a list of all hardware components in the TX Matrix Plus router (sfc 0), issue the show chassis hardware command.

In this example, TXP-F13 SIBs (F13 SIB) and TXP-F2S SIBs (F2S SIB) are installed.

user@host> show chassis hardware sfc 0
Note

The description for Routing Engine 0 and Routing Engine 1, part number 740-026942 is SFC RE before the Junos OS Release 10.3 , and RE-DUO-2600 for Junos OS Release 10.3 and later.

In this example, TXP-F13-3D SIBs (F13 SIB 3D) and TXP-F2S (F2S SIB 3D) are installed.

TX Matrix Plus Management Ethernet Interface

The TX Matrix Plus router's management Ethernet interface em0 is the interface for connecting network devices to the routing matrix through the ETHERNET port on the TXP-CB. The Junos OS automatically creates em0, but you must configure its logical interface, em0.0, with a valid IP address before you can use em0 as a management port.

Note

The Routing Engines in a router in a routing matrix do not support the fxp0 management interface, or the fxp1 and fxp2 internal Ethernet interfaces. Automated scripts that contain commands that reference fxp0, fxp1, or fxp2 must be modified to use em0, ixgbe0, and ixgbe1.

When you enter the show interfaces command, the management Ethernet and internal Ethernet interfaces (and logical interfaces) are displayed.

user@host> show interfaces

The Junos OS also creates the internal Ethernet interface, ixgbe0, which connects the Routing Engine installed into the TX Matrix Plus TXP-CB in slot 0 to the Packet Forwarding Engines in the line-card chassis (LCCs). If the TX Matrix Plus router has redundant Routing Engines, another internal Ethernet interface, ixgbe1, is created on each Routing Engine in order to support fault tolerance. Two physical links between the Routing Engines connect the independent control planes. If one of the links fails, both Routing Engines can use the other link for IP communication. The LCC CTRL PLANE ports on the TXP-CIP in the TX Matrix Plus router connect to the SFC 0 ports on the LCCs.
