Preface
Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and
S4 service requests are those in which your network is minimally impaired or for which you require
product information.) After you describe your situation, the TAC Service Request Tool provides
recommended solutions. If your issue is not resolved using the recommended resources, your service
request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests, or if you do not have Internet access, contact the Cisco TAC by telephone.
(S1 or S2 service requests are those in which your production network is down or severely degraded.)
Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business
operations running smoothly.
To open a service request by telephone, use one of the following numbers:
For a complete list of Cisco TAC contacts, go to this URL:
http://www.cisco.com/techsupport/contacts
Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity
definitions.
Severity 1 (S1)—An existing network is “down” or there is a critical impact to your business operations.
You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your
business operations are negatively affected by inadequate performance of Cisco products. You and
Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of the network is impaired while most business operations
remain functional. You and Cisco will commit resources during normal business hours to restore service
to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or
configuration. There is little or no effect on your business operations.

Chapter 1 Upgrading to a Multishelf System
Information About Upgrading to a Multishelf System
Information About Upgrading to a Multishelf System
The difference between upgrading a single-chassis system to a multishelf system and installing a
multishelf system is the fabric upgrade. A single-chassis system uses fabric cards designed for
single-chassis systems (FC/S cards), and an LCC in a multishelf system uses fabric cards designed for a
multishelf system (FC/M cards). On a single chassis system, each fabric card represents one fabric plane.
To upgrade a single-chassis system to a multishelf system without interrupting service, you must do the
following:
1. Use CLI commands to prepare each FC/S fabric card for replacement with an FC/M card.
2. Shut down the plane on each FC/S card before it is replaced.
3. Replace the FC/S card with an FC/M card.
4. Bring up the FC/M card.
5. Repeat Step 2 through Step 4 until all planes (0 through 7) are upgraded.
When you plan to perform a single-shelf to multishelf system upgrade, consider the following:
• You need these components:
–
Fabric card chassis and new line card chassis.
–
Cisco Catalyst 6509 Switch, which provides the control Ethernet network for the multishelf
system control traffic. We highly recommend two switches for redundancy.
–
S13 cards for the original line card chassis (to replace the original S123 cards in the chassis).
–
Optical array cables (48 cables for each multishelf system and 24 cables for each line card
chassis).
–
Additional MSCs and PLIMs for the new line card chassis.
• To avoid traffic loss, you must upgrade the switch fabric one plane at a time. To do that, you must
replace each FC/S card with a new FC/M card and restore service to that fabric plane before
upgrading the next fabric plane.
• You might want to perform the upgrade during a network maintenance window or when system
traffic is light.
NoteBe sure to review the upgrade procedures before deciding when to schedule the upgrade.
That way, you can familiarize yourself with the upgrade procedure and determine if there
are other issues to consider before performing the upgrade.
• Are there cabling issues to consider when you add the new chassis to the existing chassis?
For example, will you have to install optical chassis interconnect cables between the chassis before
you bolt the chassis to the floor? If so, be sure to protect the cables while moving the chassis.
How to Upgrade to a Multishelf System
To upgrade a single-chassis system to a multishelf system, you must complete the following tasks:
• Upgrading the Fabric Cards and Adding an FCC, page 1-4
• Adding an LCC to a Multishelf System, page 1-9

How to Upgrade to a Multishelf System
Upgrading the Fabric Cards and Adding an FCC
This section describes how to upgrade the fabric cards in a single-chassis system and establish
communications between the designated shelf controller (DSC) LCC and one or more FCCs.
Prerequisites
Software Requirements
• Cisco IOS XR Software Release 3.4.0 or later
• ROMMON 1.42 or later
CautionThe ROM Monitor software must be upgraded to version 1.42 or higher on all RPs before a Cisco CRS-1
system is upgraded to Cisco IOS XR Software Release 3.4.0 or higher release. If the router is brought
up with an incompatible version of the ROM Monitor software, then the standby RP may fail to boot.
For instructions to overcome a boot block in the standby RP in a single chassis system, see Cisco IOS XR ROM Monitor Guide. If a boot block occurs in a multishelf system, contact your Cisco Systems support
representative for assistance. See Obtaining Technical Assistance, page viii.
Chapter 1 Upgrading to a Multishelf System
Restrictions
SUMMARY STEPS
In addition, Cisco CRS-1 Multishelf systems should be upgraded to ROMMON release 1.42 before being
upgraded to IOS XR Release 3.4.0 to ensure RPs are assigned the correct rack numbers during system
boot.
For more information, see Cisco IOS XR ROM Monitor Guide.
Hardware Requirements
• The system hardware should be prepared as described in the “Prerequisites for Upgrading to a
Multishelf System” section on page 1-1.
• The control network must be set up as described in the “Prerequisites for Upgrading to a Multishelf
System” section on page 1-1.
• The power should be off for the FCCs and any additional LCCs.

Converting to an Integrated Switch System
This chapter describes the following concepts:
• Convert to a Cisco CRS-1 Multishelf System that uses an external Cisco Catalyst 6509 Switches, to
a system that uses integrated switches that are located on the 22-port shelf controller Gigabit
Ethernet (22-port SCGE) card.
• Remove the Cisco Catalyst switches and replace them with 22-port SCGE cards.
• Remove and replace techniques are used to complete the process.

Prerequisites for the Integrated Switch System
Hardware Requirements
• Ensure that all fabric card chassis (FCCs) have two power shelves and that all three power entry
modules (PEMs) in each power shelf are running correctly. During the conversion, when one 22-port
SCGE is removed, the chassis must have both power shelves populated to keep all the fans in the
chassis engaged.
• Two 22-port SCGE per fabric chassis.
• Four 22-port SCGE for a Two-FCC Multishelf System.
• Eight 22-port SCGE for a Four-FCC Multishelf System.
Software Requirements
• Cisco IOS XR Software Release 3.4.1 to support 22-port SCGE.
• ROMMON version 1.43 or higher
CautionBefore performing the procedures that are described in this chapter, it is important to wait until the
previous step is completed before attempting the next step. Failure to do so can result in a failure of the
migration procedure. If a previous step fails to complete successfully, contact Cisco Technical Support
before proceeding. We do not have a rollover procedure defined.
Cisco CRS-1 Multishelf Conversion to an Integrated Switch
System Introduction
The first implementation of the Cisco CRS-1 Multishelf System, the interrack control network was
established by connecting the GE ports on each LCCs route processor (RP) to two external
Cisco Catalyst 65xx switches, which, in turn, were connected to the FCCs’ shelf controller (SC) cards.
Two Cisco Catalyst 65xx switches were used to achieve redundancy, and Rapid Spanning Tree Protocol
(RSTP) was used to ensure a loop-free topology.
In the first release of the Cisco CRS-1 Multishelf System (running Cisco IOS XR Software
Release 3.2.50), two Cisco Catalyst 65xx switches are interconnected to the multishelf’s fabric card
chassis (FCC0, FCC1, FCC2, and FCC3) and two line card chassis (LCC0 and LCC1) to form the
interchassis control network.
The 22-port SCGE card replaces the current 2-port SCGE card in the multishelf system (MSS) FCC. The
22-port SCGE card contains built-in bundled Gigabit Ethernet (GE) switches. The 22-port SCGE card is
designed to integrate the functionality of the two Cisco Catalyst 65xx switches. With the new 22-port
SCGE card, all Layer 2 system switching is now bundled and integrated into the Cisco CRS-1 router. On
the 22-port SCGE card, there are 22 ports available on the front panel. Each port on the 22-port SCGE
card has two LEDs, which indicate port activity and link state.
When the 22-port SCGE cards are installed, the control network topology ceases to be a simple
hub-and-spoke set of connections.

Cisco CRS-1 Carrier Routing System Multishelf System Upgrade and Conversion Guide
OL-12571-01
Chapter 2 Converting to an Integrated Switch System
Benefits of the Cisco CRS-1 Multishelf Integrated Switch Solution
Cisco CRS-1 Multishelf Integrated Switch Solution
When the Cisco Catalyst 65xx switches are phased out of the multishelf network, the new 22-port SCGE
cards, which are installed in the Cisco CRS-1 Multishelf FCCs, are connected directly to the
Cisco CRS-1 Multishelf LCC RPs. The Cisco CRS-1 RP is a system controller that performs route
processing and distributes forwarding tables to the line cards. Although each routing system contains
two RPs, only one RP is active at a time. The other RP operates in standby mode if the active RP fails.
To perform the conversion, you need to know how to view and use the STP on the Cisco Catalyst 65xx
switch through the console port.
NoteThe Cisco Catalyst 65xx switches are typically configured so that one is the root of the spanning tree,
and the other one is the backup root. All the ports in the root switch are in the forwarding state.
Before the conversion to the 22-port SCGE, if you have two ports from the RP connected to a
Cisco Catalyst 65xx switch, you should see one RP port in forwarding state, and the other RP port in
blocked state.
RSTP is used to break the interchassis loops in the Layer 2 control network.
NoteLoops can happen only when a port is transitioning from a down state to an up state.
Benefits of the Cisco CRS-1 Multishelf Integrated Switch
Solution
The following benefits are described for migrating from a Cisco Catalyst 65xx switch-based control
network for the multishelf system to a bundled 22-port SCGE integrated switch solution:
• The Cisco Catalyst switches are configured with Cisco IOS software through a separate
command-line interface (CLI). But the integrated 22-port SCGE switches are configured from the
Cisco CRS-1 router console by using the Cisco IOS XR software, which is the same operating
system used by the Cisco CRS-1 router. The control network is easier to connect and manage.
• There is no longer any need for two dedicated Catalyst switches per multichassis system.
Naming Conventions
The following naming conventions are used in this document:
• The fabric chassis upper cage shelf controller card and its slot are both referred to as SC0.
• The lower cage shelf controller card and slot are referred to as the SC1.
• There are two SC cards in every FCC for the purpose of redundancy.
OL-12571-01
• The active Cat6K remains active in the Cisco CRS-1 Multishelf control network.

Step 4Repeat Step 1 to Step 3 for the remaining FCC.
Connecting the 22-port SCGE to an Active Cat6K (Single-FCC Multishelf and
Two-FCC Multishelf Systems)
To connect the standby 22-port SCGE to an active Cat6K and connect the 22-port SCGEs to each other
in a full mesh configuration, perform the following steps:
Step 1Connect one port of the standby 22-port SCGE in each fabric chassis to the active Cat6K. Enable STP
and portfast on these ports from the Cisco Catalyst 65xx switch side.
Step 2Connect the two newly inserted standby 22-port SCGE cards to each other in a Two-FCC Multishelf
System.
Step 3Use the show controller switch inter-rack stp command in administration EXEC mode, with the
location keyword, to verify that all the new connections and ports are working correctly.
Step 4Verify that the connected ports are bidirectional and that the port neighbors are correct by using the show
controllers switch inter-rack udld command, with the all and location keywords, in administration
EXEC mode, as shown in the following syntax:
show controllers switch inter-rack udld {all location node-id}
Replace the node-id argument with the newly inserted standby 22-port SCGE card.
OL-12571-01
In addition, verify that the port is connected to an active Cat6K and is in the forwarding state (FWD) by
using the show controllers switch inter-rack stp command, with the ports and location keywords, in
administration EXEC mode, as shown in the following syntax:
show controller switch inter-rack stp {ports interface number location node-id}
Cisco CRS-1 Carrier Routing System Multishelf System Upgrade and Conversion Guide
2-5
Chapter 2 Converting to an Integrated Switch System
How to Convert from the Cisco Catalyst 65xx Switch to the Integrated Switch System for Single-FCC Multishelf and
Two-FCC Multishelf Systems
Replace the interface number argument with the port that is connected to the active Cat6k.
Replace the node-id argument with the newly inserted standby 22-port SCGE card.
The following example sample output displays information for STP from the show controllers switch inter-rack stp command:
RP/0/RP0/CPU0:router(admin)# show controllers switch inter-rack stp ports 0 location
GE_0 of MST1 is designated forwarding
Edge port: no (default) port guard : none (default)
Link type: point-to-point (auto) bpdu filter: disable (default)
Boundary : internal bpdu guard : disable (default)
Bpdus (MRecords) sent 204605, received 8
For the 22-port SCGE ports which are connected to each other, one is in the forwarding state and the
other is in the blocked state.
Transferring the Backup Cisco Catalyst 65xx Switch Gigabit Ethernet
Connections to a Standby 22-port SCGE (Single-FCC Multishelf and Two-FCC
Multishelf Systems)
To transfer the backup Cisco Catalyst 65xx switch GE connections to a standby 22-port SCGE card and
to isolate the backup Cisco Catalyst 65xx switch from the control network, perform the following steps:
Step 1Shut down the ports on the backup Cat6K one at a time. Make the interCat6K port the last port to shut
down.
Step 2Move the disabled GE connections between the active RPs (on both the LCC in case of a 2 FCC MC)
and the backup Cat6K to the standby 22-port SCGE.
Step 3Use the show controllers switch stp command, with the location keyword, in administration EXEC
mode, to verify that the RP ports (GE1) that are connected to the 22-port SCGE are in the blocked state,
and that the RP ports (GE0) that are connected to an active Cat6K are in the forwarding state, as shown
in the following syntax:
show controllers switch inter-rack stplocationnode-id
Replace the node-id argument with the location of the 22-port SCGE card. In addition, you can use the
newly inserted standby 22-port SCGE card.

Chapter 2 Converting to an Integrated Switch System
How to Convert from the Cisco Catalyst 65xx Switch to the Integrated Switch System for Single-FCC Multishelf and
Two-FCC Multishelf Systems
Performing a Failover to a Standby 22-port SCGE (Single-FCC Multishelf and
Two-FCC Multishelf Systems)
To perform a failover to a standby 22-port SCGE and swap the remaining 2-ports SCGE in the system
with the new 22-port SCGEs, perform the following steps:
Step 1Perform a failover of the current active 2-ports SCGE card to the standby 22-port SCGE card. Use the
redundancy switchover command, with the location keyword, in EXEC mode, as shown in the
following syntax:
redundancy switchoverlocationnode-id
Replace the node-id argument with the location of the active 2-ports SCGE card.
Step 2Verify that the failover is completed and that the 22-port SCGE card is now in active mode by using both
the show platform command and show redundancy command.
The show platform command shows that the 22-port SCGE card is in IOS XR RUN state.
The show redundancy command shows that the 22-port SCGE card is in the active role.
Step 3After the 22-port SCGE becomes active, swap the 2-ports SCGE card (now in standby mode) with a new
22-port SCGE card.
NoteDo not attempt this step before Step 2 has completed.
Step 4Use the show platform command in EXEC mode or administration EXEC mode to verify that the newly
inserted 22-port SCGE card is in the IOS XR RUN state, as shown in the following example:
RP/0/RP0/CPU0:router(admin)# show platform

Step 5Repeat Step 1 to Step 4 for the other fabric chassis on a two-FCC MC.
Connecting the 22-port SCGEs into a Full Mesh (Single-FCC Multishelf and
Two-FCC Multishelf Systems)
To connect the 22-port SCGEs in a full mesh configuration, perform the following steps:
Step 1Connect each of the 22-port SCGE card to every other 22-port SCGE card in the system. For a one-FCC
MC, this means one connection from the active 22-port SCGE card to the standby 22-port SCGE card.
For a two-FCC MC, this means each 22-port SCGE card has three connections to the other three 22-port
SCGE cards in the system. This constitutes a full mesh connectivity between the 22-port SCGE cards.
Step 2Verify that all of the connected ports are bidirectional and that all of the neighbors are correct by using
the show controllers switch inter-rack udld command, with the all and location keywords, in
administration EXEC mode, as shown in the following syntax:
show controllers switch inter-rack udld {all location node-id}
Replace the node-id argument with the location for all of the 22-port SCGE card in the system.
Step 3Verify that all of the connected ports to 22-port SCGE cards are displayed as either in forwarding (FWD)
state or blocked (BLK) state for all of the 22-port SCGE cards in the system by using the show
controller switch inter-rack stp command, with the location keyword, in administration EXEC mode.
The location is used for all of the 22-port SCGE cards in the system.
The following example shows location f0/sc0/cpu0:
RP/0/RP0/CPU0:router(admin)# show controllers switch inter-rack stp location f0/sc0/cpu0

Root this switch for the CIST
Operational hello time 1, forward delay 6, max age 8, txholdcount 6
Configured hello time 1, forward delay 6, max age 8, max hops 4
Transferring an Active Cat6K Gigabit Ethernet Connections to the Active 22-port
SCGE (Single-FCC Multishelf and Two-FCC Multishelf Systems)
To transfer the active Cat6K GE connections to the active 22-port SCGE and isolate the active Cat6K
from the control network, perform the following steps:
Step 1Disable the active Cat6K links that are connected to the active RP on the Designated Shelf Controller
(DSC).
Step 2Use the show controllers switch inter-rack stp command in administration EXEC mode to verify on
the active RPs that the GE1 port, which is connected to the 22-port SCGE, goes into the forwarding
(FWD) state.
The location is the location of the active RP.
Step 3Shut down the ports on the active Cat6K one at a time, with the exception of the four links between an
active Cat6K and the 22-port SCGE. Now, the active Cat6K remains connected to the fabric chassis with
four GE links.
Step 4Use the show controllers switch inter-rack stp command in administration EXEC mode to verify on
all RPs that the GE1 port, which is connected to the 22-port SCGE, goes into the forwarding (FWD)
state.
Step 5Move the disabled GE link connecting the RPs and the active Cat6K link to the 22-port SCGE card.
Step 6Use the show controllers switch inter-rack stp command in administration EXEC mode to verify on
all RPs that the GE0 port, which is connected to the 22-port SCGE, goes into the blocked (BLK) state.
Step 7Raise the priority of active Cat6K to 40960, which causes the root to change to 22-port SCGE on rack
FCC0.
Step 8Use the show controllers switch inter-rack stp command in administration EXEC mode to verify that
the active SC on FCC0 is the new root switch.
Step 9Shut down the port that is connected to the active Cat6K on each of the 22-port SCGEs.
OL-12571-01
Step 10Verify that there is no impact to the active topology and the control Ethernet traffic.
The migration is complete after you validate the new connections. You can remove the two
Cisco Catalyst 65xx switches.

Validating the 22-port SCGE Cards (Four-FCC Multishelf System)
To validate the 22-port SCGE cards, perform the following steps:
Step 1Insert the 22-port SCGE card into the standby slot (SC-GE-2) of FCC. Remove the 2-port card that is
already installed.
Step 2Use the show platform command in EXEC mode or administration EXEC mode to verify that the
22-port SCGE card is in the IOS XR RUN state.
Step 3Use the show redundancy command in EXEC mode to verify that the standby node is ready.
Step 4Repeat Step 1 to Step 3 for all eight 22-port SCGE cards. Verify the two per fabric chassis by using the
standby slot and leaving the second 22-port SCGE in the standby slot to continue with the upgrade.
Connecting the 22-port SCGE to an Active Cat6K (Four-FCC Multishelf System)
To connect the standby 22-port SCGE to an active Cat6K and connect the 22-port SCGEs to each other
in a full mesh configuration, perform the following steps:
Step 1Connect one port of the standby 22-port SCGE in each fabric chassis to the active Cat6K. Enable STP
and portfast on these ports from the Cisco Catalyst 65xx switch side. If there are not enough ports on the
active Cat6K, use the ports that were previously connected to the standby SCs in the four fabric chassis.
Step 2Connect the ports to each other in a full mesh configuration for the 22-port SCGE.
2-10
Step 3Use the show controller switch inter-rack stp command in administration EXEC mode, with the
location keyword, to verify that all the new connections and ports are working correctly.
Step 4Use the show controllers switch inter-rack udld command in administration EXEC mode, with the all
and location keywords, to verify that all the ports for the 22-port SCGE are connected to the active
Cat6K in the forwarding state.
The node-id argument is the location of the 22-port SCGE cards.

Chapter 2 Converting to an Integrated Switch System
How to Convert from the Cisco Catalyst 65xx Switch to the Integrated Switch System for a Four-FCC Multishelf System
The following example shows how to display information for the Spanning Tree Protocol (STP) from
the show controllers switch inter-rack stp command:
RP/0/RP0/CPU0:router(admin)# show controllers switch inter-rack stp ports 0 location
GE_0 of MST1 is designated forwarding
Edge port: no (default) port guard : none (default)
Link type: point-to-point (auto) bpdu filter: disable (default)
Boundary : internal bpdu guard : disable (default)
Bpdus (MRecords) sent 204605, received 8
For the 22-port SCGE ports which are connected to each other, one is in the forwarding state and the
other is in the blocked state.
Step 5Use the show controller inter-rack stp command in administration EXEC mode, with the location
keyword, to verify the connection between the 22-port SCGE card. The active Cat6K goes into
forwarding state.
The location is the location of the 22-port SCGE card.
The following example shows location f0/sc0/cpu0:
RP/0/RP0/CPU0:router(admin)# show controllers switch inter-rack stp location f0/sc0/cpu0

Transferring the Backup Cisco Catalyst 65xx Switch Gigabit Ethernet
Connections to a Standby 22-port SCGE (Four-FCC Multishelf System)
OL-12571-01
To transfer the backup Cisco Catalyst 65xx switch GE connections to a standby 22-port SCGE and to
isolate the backup Cisco Catalyst 65xx switch from the control network, perform the following steps:
Step 1Shut down the ports on the backup Cat6K one at a time. Make the interCat6K port the last port to shut
down.
Cisco CRS-1 Carrier Routing System Multishelf System Upgrade and Conversion Guide

Chapter 2 Converting to an Integrated Switch System
How to Convert from the Cisco Catalyst 65xx Switch to the Integrated Switch System for a Four-FCC Multishelf System
Step 2Move the disabled GE links between RPs and the backup Cat6K to the newly inserted 22-port SCGE
cards. The following locations are listed:
• 0/rp0-GE1 to F1/SC1-GE0
• 0/rp1-GE1 to F3/SC1-GE0
• 1/rp0-GE1 to F0/SC1-GE0
• 1/rp1-GE1 to F2/SC1-GE0
Step 3Use the show controllers switch inter-rack udld command in administration EXEC mode, with the all
and location keywords, to verify that all of the new connections are bidirectional and have the correct
neighbors.
The location is the location of the 22-port SCGE card.
Step 4Use the show controllers switch stp location command in administration EXEC mode to verify that RP
ports (GE1) that are connected to the 22-port SCGE are in the blocked state, and that the RP ports (GE0)
that are connected to the active Cat6K are in the forwarding state.
Step 5Verify that there is no impact to the active topology and the control Ethernet traffic because the active
Cat6K remains as the root.
Performing a Failover to a Standby 22-port SCGE (Four-FCC Multishelf System)
To perform a failover to a standby 22-port SCGE and swap the remaining SCGE with the new 22-port
SCGEs, perform the following steps:
Step 1Perform a failover to an FCC0, to the new 22-port SCGE. Use the following syntax for the redundancy
switchover command, with the location keyword, in EXEC mode:
redundancy switchover location node-id
Replace the node-id argument with the location of the active 2-ports SCGE card.
Step 2Verify that the failover is completed by using the show platform command and show redundancy
command.
The show platform command shows that the 22-port SCGE card is in IOS XR RUN state.
The show redundancy command shows that the 22-port SCGE card is in the active state.
Step 3After the 22-port SCGE becomes active, swap the 2-ports SCGE (active SC) with the new 22-port SCGE
card.
NoteDo not attempt this step before Step 2 has completed.
Step 4Use the show platform command in EXEC mode or administration EXEC mode to verify that the newly
22-port SCGE is in the IOS XR RUN state.
2-14
Step 5Use the show redundancy command in EXEC mode to verify that the newly inserted 22-port SCGE
cards are in standby ready.
Step 6Repeat Step 1 to Step 4 for FCC1, FCC2, and FCC3.

Chapter 2 Converting to an Integrated Switch System
How to Convert from the Cisco Catalyst 65xx Switch to the Integrated Switch System for a Four-FCC Multishelf System
Connecting the 22-port SCGEs into a Full Mesh Configuration (Four-FCC
Multishelf System)
To connect the 22-port SCGEs in a full mesh configuration, perform the following steps:
Step 1Connect all of the 22-port SCGE cards to every other 22-port SCGE cards in the system in a mesh
connection topology. Every 22-port SCGE card has seven connections to other 22-port SCGE cards.
Step 2Verify that all new connections are bidirectional and connected to the right neighbors by using the show
controllers switch inter-rack udld command, with the all and location keywords, in administration
EXEC mode, as shown in the following syntax:
show controllers switch inter-rack udld {all location node-id}
Replace the node-id argument with the location of all of the 22-port SCGE cards.
Step 3Verify that all of the connected ports to the 22-port SCGE cards are displayed as either in forwarding
(FWD) state or blocked (BLK) state for all of the 22-port SCGE cards in the system by using the show
controller switch inter-rack stp command, with the location keyword, in administration EXEC mode.
The location is used for all of the 22-port SCGE cards in the system.
The following example shows location f0/sc0/cpu0:

Chapter 2 Converting to an Integrated Switch System
How to Convert from the Cisco Catalyst 65xx Switch to the Integrated Switch System for a Four-FCC Multishelf System
Transferring an Active Cat6K Gigabit Ethernet Connections to the Active 22-port
SCGE (Four-FCC Multishelf System)
To transfer an active Cat6K GE connections to the active 22-port SCGE and isolate the active Cat6K
from the control network, perform the following steps:
Step 1Disable the active Cat6K port that is connected to the active RP on the DSC.
Step 2Use the show controllers switch inter-rack stp command in administration EXEC mode to verify on
the active RPs that the GE1 port, which is connected to the 22-port SCGE, goes into the forwarding
(FWD) state. The location is the location of the active RP.
Step 3Shut down the ports on the active Cat6K one at a time, with the exception of the four links between the
active Cat6K and the 22-port SCGE. Now, the active Cat6K remains connected to the fabric chassis with
four GE links.
Step 4Use the show controllers switch inter-rack stp command in administration EXEC mode to verify on
all RPs that the GE1 port, which is connected to the 22-port SCGE, goes into the forwarding state.
Step 5Move the disabled GE links from the RP to the active Cat6K to the 22-port SCGE. The following
locations are listed:
• 0/rp0-GE0 to F0/SC0-GE0
• 0/rp1-GE0 to F2/SC0-GE0
• 1/rp0-GE0 to F1/SC0-GE0
• 1/rp1-GE0 to F3/SC0-GE0
Step 6Verify that all of the connections are bidirectional and have the correct neighbors by using the show
controller switch inter-rack udld command, with the all and location keywords, in administration
EXEC mode, as shown in the following syntax.
show controllers switch inter-rack udld {all location node-id}
Replace the node-id argument with the location of all of the 22-port SCGE card.
Step 7Use the show controllers switch inter-rack stp command in administration EXEC mode to verify on
all RPs that the GE0 port, which is connected to the 22-port SCGE, goes into the blocked (BLK) state.
Step 8Raise the priority of the active Cat6K to 40960, which causes the root to change to the 22-port SCGE on
rack FCC0.
Step 9Use the show controllers switch inter-rack stp command in administration EXEC mode to verify that
the active SC on FCC0 is the new root switch.
Step 10Shut down the port that is connected to active Cat6K to each of the 22-port SCGEs.
The migration is complete after you validate the new connections. You can remove the two
Cisco Catalyst 65xx switches.
