files in plain text or PDF (Acrobat reader) format.
 Installation Instructions
Copyright IBM Corp. 1998
Page 5
June 17 1998EC : F34705PN : 26L0227

These files must be placed in a directory reachable through TFTP, like /tmp for a Unix/AIX
station, so that In-Band download toward the CPSW can be performed.
After package file has been downloaded and unzipped, on an AIX Workstation make sure
that the files can be read by all users :
Log in as "root" Set the path to the microcode files directory
Enter: chmod a+r BOOTV319.BIN
Enter: chmod a+r 8260V319.OPE
Enter: chmod a+r SWPGAB52.ENC
1.3 In-Band download method
You need to perform an inband download operation, using either:
ww Classical IP mode. Make sure that your ATM network is configured for IP Over ATM
(RFC 1577). To configure your ATM network for IP over ATM:
1 Connect an ARP server to the ATM network. The ARP server will be used to map IP
addresses to ATM addresses.
2 For each A-CPSW module verify that the following parameters are configured:
Ø ATM address of the ARP server
Ø IP address and IP mask of the A-CPSW
Ø IP address of the default gateway
3 Verify the IP connectivity to the ARP server by entering a PING command for each A-CPSW
module.
4 Verify the IP connectivity to the TFTP server by entering a PING command for each A-CPSW
module.
ww Ethernet or Token Ring LAN-Emulation mode
Make sure your network is configured in Ethernet or Token Ring
LAN-Emulation.
To configure your network in Ethernet or Token Ring LAN-Emulation :
1. You must have an Ethernet or Token Ring LAN-Emulation Server configured and ready.
You can use the local LES of the 8260.
2. You must configure the Ethernet or Token Ring LAN-Emulation Client on your 8260.
3. You must have a TFTP Server somewhere in the IP network (either on the Emulated LAN,
either behind an IP Gateway), and the microcode files installed on that TFTP Server.

June 17 1998EC : F34705PN : 26L0227

4. Check that you can PING the TFTP server from the 8260 LEC.
ww Serial Line IP support (SLIP) mode.Make sure your workstation can act as a TFTP
server .
1. Set up a A-CPSW Configuration Console in SLIP Mode:
2. Then configuring the SLIP interface on the TFTP workstation will allow you to perform Inband
Download between your workstation and the A-CPSW.
3. The SLIP connection will be broken after a reset of the A-CPSW and connection will be
operational in normal mode.
1.4 Out of Band Download method
 FPGA picocode cannot be downloaded using this method, only boot and operational.
 Download can only be performed on active CPSW.
Once you have the code on your A-disk or hard disk, and you have connected your PC on the
RS232 port, using an RS232 emulated terminal, you have to type the following commands on
the command line: MAINTAIN
DOWNLOAD OUT-OF-BAND BOOT (or OPERATIONAL)
You then have to choose the Xmodem protocol and select the path where your code is
located.
Note: This method is not recommended since it takes more time than the In-Band
method.

2 Upgrading the 8260
YOU SHOULD MIGRATE YOUR NETWORK CLUSTER BY CLUSTER AND YOU
SHOULD DOWNLOAD THE FPGA CODE AND MICROCODE ON ALL YOUR 8260
AND 8285 SWITCHES (in the cluster) BEFORE PERFORMING ANY SWAP
COMMAND.
Note that interoperability between v.2.x.x clusters and v.3.x.x peer groups is possible through
NNI/IISP respectively.
 IMPORTANT
The following steps are showing an example of Inband Download.
You may log in to the A-CPSW console either locally using an ASCII terminal connected
to the A-CPSW console port, or remotely using a TELNET session. PLEASE, READ
WHAT FOLLOWS CAREFULLY :
1. If you have only one A-CPSW (no redundant) follow the steps 1 to 4 then the steps 6 to 8.
2. If you have two A-CPSWs modules (one redundant A-CPSW) follow the steps 1 to 5 for main
A-CPSW and the steps 2 to 4 then 6 for redundant A-CPSW .Then follow the steps 6, 7 and 8 on
main A-CPSW (see upgrade synopsis).
2.1 Step 1: Saving Configuration before the upgrade
It is recommended to perform the following steps with NO OPERATIONAL TRAFFIC
flowing in your ATM campus network. Typically, this would be scheduled as part of a
maintenance period. You should save all your configuration parameters before.
Before you begin the upgrade procedure we recommend to upload the configuration of each

---ATM ADDRESS SETTING ---------------------------------------------------
After having completed the swap, the ATM address has been migrated to the Node-0
ATM address, but the PNNI Summary Address was set to a default value. So you need
to enter the old ATM address again, with a new selector, by issuing the following
command :
o HUBa>set pnni node_0 atm_address:
39.99.99.99.99.99.99.00.00.77.77.01.01.00.00.82.60.01.01.01
o HUBa>SHOW FUTURE_PNNI NODE_0
Check your new ATM address.
o HUBa>COMMIT PNNI , the 8260 will be reset
The telnet session if any is broken.
Login as ADMINISTRATOR on the 8260 console.
o HUBa>SHOW PNNI NODE_0
Check your ATM address. It will display information about : LEVEL
ID, PEERGROUP ID, NODE ID.

After having completed the swap, the ATM address has been migrated to the
Node-0 ATM address, but the PNNI Summary Address was set to a default value.
So you need to enter the old ATM address again, with a new selector, by issuing the
following command :
o HUBb>set pnni node_0 atm_address:
39.99.99.99.99.99.99.00.00.77.77.01.02.00.00.82.60.01.02.01

Login as ADMINISTRATOR on the 8260 console.
o HUBb>SHOW PNNI NODE_0
Check your ATM address. It will display information about : LEVEL
ID, PEERGROUP ID, NODE ID.
---- PORT SETTING -----------------------------------------------------------------
After having completed the swap, the SSI port automatically became an enabled PNNI
port and the NNI port became a disabled IISP port, so you need to re-enable the IISP
port only:
1. Enable all your old NNI port (now IISP) as VOID port.
HUBb>SET PORT 3.1 ENABLE VOID
2. SETTING FOR UNI PORT. No change is needed for the port set as UNI
before the migration, the port 4.3 of HUBb has been left after migration as UNI
enabled.

For each LOGICAL LINK in v2.x.x (if VPI was not equal to 0) you must define a VPC
link in v3.1.0 :
1. To set your new VPC_LINKS, YOU NEED THE V2.X.X PARAMETERS YOU
HAVE WRITTEN DOWN IN STEP 6.
example for old CLUSTER 1 HUB b (figure2), now PEER GROUP 1,HUB b (fig 3):
The VPI on the LOGICAL LINK 3.1 was 3.
Use VPI 3 to set up the new VPC_LINK.
