Question 1

An engineer is performing an ISSU upgrade on the Cisco MDS 9000 Series Switch. What is the impact on the control plane of the switch?

  • A. It is down for less than 80 seconds.
  • B. It remains down for more than 80 seconds but less than 140 seconds.
  • C. It remains down until the next reboot.
  • D. It remains up throughout the update.

Answer:

On a 95xx or 97xx Series MDS with dual supervisors, during the firmware upgrade, the new code is loaded on the standby supervisor. A switchover then occurs in order to make the supervisor that runs the new code active. The code is then loaded on the previously active supervisor, and it becomes the new standby supervisor. The data plane continues to pass fibre channel traffic. The modules then non-disruptively start at the lowest numbered module and proceed to the highest.
On a 91xx, 92xx, or 93xx Series MDS, which has only one supervisor, the supervisor (control plane) is reloaded. The data plane continues to pass fibre channel traffic.
If you intend to upgrade via Telnet, Secure Shell (SSH), or Simple Network Management Protocol (SNMP) (Fabric Manager/Device Manager), ensure that you have an Ethernet connection to both of the supervisors. After the Telnet session is lost during the upgrade, you must reconnect to the switch. You will connect to the previous standby supervisor now.

Question 5

Which two statements describe the process of performing an EPLD upgrade on a Cisco MDS 9000 Series Switch? (Choose two.)

  • A. The upgrade is performed from the standby supervisor module.
  • B. The upgrade process disrupts only the module that is being upgraded.
  • C. The upgrade is performed on the active supervisor.
  • D. If an upgrade is interrupted, the upgrade continues after a connection is restored.
  • E. Modules must be online to be upgraded.
Mark Question:
Answer:

When you upgrade or downgrade the EPLDs, observe the following guidelines and limitations:
You can upgrade each module only when it is online. The EPLD upgrade is only disruptive to the module being upgraded.
If you interrupt an EPLD upgrade or downgrade, the module must be upgraded again.
In Cisco MDS 9000 Director Switches, EPLD upgrade or downgrade can only be executed from the active supervisor module. To upgrade the supervisor
EPLDs nondisruptively, upgrade the standby supervisor and then switchover. After the new standby supervisor is online, its EPLDs can be upgraded.
In Cisco MDS 9000 Series Fabric Switches, be sure to specify 1 as the module number. The switch must be power cycled for the EPLDs to start running the new code.
