Issue Upgrading to ExtremeXOS 30.7 Using ExtremeCloud on ExtremeSwitching X435 Switches

For ExtremeSwitching X435 switches with 8-port module, when using ExtremeCloud IQ to download ExtremeXOS 30.7, the switch might become unreachable by ExtremeCloud IQ after the switch reboots and comes up running ExtremeXOS 30.7. This only occurs when using DHCP to obtain an IP address on the switch.

When upgrading from ExtremeXOS 30.5 or 30.6, or any patches of these two releases, you need to logon to the switch using SSH (SSH access is available using ExtremeCloud IQ SSH proxy feature) and perform one of the following options:

Note

ExtremeXOS 30.5 and its patch releases only support manual upgrading of images.

• DHCP—Run the command enable dhcp vlan Default, and then save the configuration. This assumes the VLAN is “Default”. If not default VLAN, run enable dhcp vlan <X>.
• Static IP Address—Statically configure IP address and default gateway on the VLAN for external management access, and then save the configuration.
• Unconfigure Switch—Download ExtremeXOS 30.7 from an external site—not from the ExtremeCloud IQ URL, run the command unconfigure switch all, and then reboot.
