Stacking Avaya VSP 7000 using Fabric Interconnect

Task

Create the stack of Avaya VSP 7000 switches using Fabric Interconnect.


Scenario

There are two Avaya VSP 7000 switches, which should be working as one stack. The switches are new and have the factory default settings. The firmware upgrade is not necessary, but it can be made. I will create the stack in a half ring using non-redundant cabling and FI down pair-cable configuration.


 Hardware | Software

  • Switch: Avaya VSP 7024XLS + VOSS v10.4.0.003 (x2)

Solution | Overview

Step 1: Prepare the stack BASE UNIT (master).

Step 2: Prepare the NON-BASE UNIT (slave).

Step 3: Fabric Interconnect BASE UNIT with NON-BASE UNIT.

Step 4: Verify the stack.


Solution | Detailed

Step 1: Prepare the stack BASE UNIT (master).

a) Configure the main parameters in global configuration.

stack-monitor trap-interval 30
stack-monitor stack-size 2
stack-monitor enable
stack reboot-on-failure 
stack forced-mode
stack auto-unit-replacement enable
stack auto-unit-replacement-image enable
  • stack-monitor trap-intervalSets the trap interval value, default is 60.
  • stack-monitor stack-sizeSets the stack size to be monitored. Values range from 2 to 8, default is 2.
  • stack-monitorConfigures the monitoring of stack switch units to detect problems within the stack.
  • stack reboot-on-failureEnables or disables rebooting of stack units when stack communication fails.
  • stack forced-modeEnables or disables Stack Forced Mode for switch units that are part of a stack.
  • stack auto-unit-replacementEnables or disables Auto Unit Replacement (AUR) for switch units that are part of a stack.
  • stack auto-unit-replacement-imageEnables or disables Agent Auto Unit Replacement (AAUR) for switch units that are part of a stack.

b) Switch down the BASE button on stack master’s front panel.

c) Remove switch & stack ip addresses, configure and verify new stack and switch ip address.

no ip address switch
no ip address stack 
ip address switch 10.10.10.11
ip address stack 10.10.10.10 mask 255.255.255.224
sh ip address
*************
                      Configured          In Use              Last BootP/DHCP
                      ---------------     ---------------     --------------------
Stack IP Address:     10.10.10.10         10.10.10.10         0.0.0.0
Switch IP Address:    10.10.10.11         0.0.0.0
Stack Subnet Mask:    255.255.255.224     255.255.255.224     0.0.0.0

Step 2: Prepare the NON-BASE UNIT (slave).

a) Configure the main parameters in global configuration.

stack-monitor trap-interval 30
stack-monitor stack-size 2
stack-monitor enable
stack reboot-on-failure 
stack forced-mode
  • stack-monitor trap-intervalSets the trap interval value, default is 60.
  • stack-monitor stack-sizeSets the stack size to be monitored. Values range from 2 to 8, default is 2.
  • stack-monitorConfigures the monitoring of stack switch units to detect problems within the stack.
  • stack reboot-on-failureEnables or disables rebooting of stack units when stack communication fails.
  • stack forced-modeEnables or disables Stack Forced Mode for switch units that are part of a stack.

b) Switch up the BASE button on stack slave’s front panel.

c) Remove switch & stack ip addresses, configure and verify new stack and switch ip address.

no ip address switch
no ip address stack 
ip address switch 10.10.10.12
ip address stack 10.10.10.10 mask 255.255.255.224
sh ip address
*************
                      Configured          In Use              Last BootP/DHCP
                      ---------------     ---------------     --------------------
Stack IP Address:     10.10.10.10         10.10.10.10         0.0.0.0
Switch IP Address:    10.10.10.12         0.0.0.0
Stack Subnet Mask:    255.255.255.224     255.255.255.224     0.0.0.0

Step 3: Fabric Interconnect BASE UNIT with NON-BASE UNIT.

a) Power off the NON-BASE UNIT.

b) Connect the FI Cables, Use the FI down pair-cable configuration (BASE UNIT on the top).

c) Power on the NON-BASE UNIT, wait for image upgrade.

Step 4: Verify the stack.
