A.2 CISCO SWITCH CONFIGURATION

Note: Contact My Oracle Support atleast 48 hours before the scheduled start of the switch configuration process, to obtain the Enable secret key.

Table A-2 CISCO SWITCH CONFIGURATION

STEP # This procedure configures the Cisco Switches on an Installed APPB ELAP Server Pair. Check off (√) each step as it is completed. Boxes have been provided for this purpose under each step number.If this procedure fails, contact My Oracle Supportand ask for ASSISTANCE.

1.

☐

Make the cross-over cable connections.

NOTE: THIS IS IMPORTANT

CONNECT the cross-over cable from Port 1 of Switch1A to Port 1 of Switch1B.

DISCONNECT the cross-over cable from Port 2 of Switch1A to Port 2 of Switch1B.

Similarly, while Configuring Switch1C and Switch1D, disconnect the cable from port 24 and reconnect post configuration.

Please note that the switch configuration should only be attempted by a skilled technician and not all.

All uplinks should be removed while switch configuration.

There should not be any loop in the switches during their configuration.

Switch1B must be configured first.

The following should be the sequence of switch configuration.

Switch1B > Switch1A > Switch1C > Switch1D

Make sure to enable and start tftp service by using following commands if not started earlier :

sudo systemctl start tftp
sudo systemctl enable tftp

2.

☐

Use minicom to access the Cisco switch console. Run minicom switch1A if the console cable is connected to MPS-A and minicom switch1Bif the console cable is connected to MPS-B.

Run minicom switch1A if the console cable is connected to MPS-A and minicom switch1Bif the console cable is connected to MPS-B.

For example:

[root@Donut-B ]#
[root@Donut-B ]# minicom switch1B
