Integrated Switch System

Router#

The output of this command should display “connected.” If it does not, then the connector may have a partial fiber cut or a bad optic. You may need to jiggle the GBIC wire to ensure that it is firmly inserted. Re-enter the command show interface until the port displays a status of “connected” or “disabled” for every port that displays a connector type.

Caution If this problem is not resolved and the Cisco CRS-1 router enters the forwarding state, a loop occurs.

Integrated Switch System

Integrated switches are two Gigabit Ethernet switches placed on system controller cards in the fabric chassis. The system controller card is called 22-port shelf controller Gigabit Ethernet (22-port SCGE), because it contains 22 ports on the front panel.

Each 22-port SCGE card provides 22 Gigabit Ethernet (GE) links, which are used to interconnect control network connections of the different Cisco CRS-1 chassis.

Note When the 22-port SCGE cards are installed, there is no requirement for an external switch device (Catalyst 6509) to provide control Ethernet connectivity.

For information about the cabling schemes for a single-FCC multishelf system, two-FCC multishelf system, and four-FCC multishelf system, see Cisco CRS-1 Carrier Routing System Multishelf System Interconnection and Cabling Guide.

Prerequisites for an Integrated Switch System

The following prerequisites are presented for the integrated switch system:

•Software Requirements, page 3-20

•Hardware Requirements, page 3-21

Software Requirements

•Requires ROMMON 1.43 or higher on all RP and 22-port SCGE nodes. The 22-port SCGE card comes with ROMMON 1.43 or later version.

Note ROMMON 1.43 is the first ROMMON version to support 22-port SCGE cards and other cards.
