Upgrading from ExtremeWare v6.1 to v6.2
ExtremeWare v6.2.1 Release Notes Page 9
• Extreme Automatic Protection Switching (EAPS) — Support for fast protection switching to layer 2
switches interconnected in an Ethernet ring topology.
• Virtual Redundant Router Protocol (VRRP) — Support for the proposed IETF standard protocol that
allows multiple switches to provide redundant routing services to users
• Network Address Translation (NAT) — Ability to convert a set of IP addresses, typically private IP
addresses, to another set of IP addresses, typically public Internet IP addresses.
• Network login — Ability to control the admission of user packets into a network by giving
addresses only to users that have been properly authenticated.
Upgrading from ExtremeWare v6.1 to v6.2
If you are currently running a release of ExtremeWare v6.1 on a Summit or BlackDiamond switch, you
must upgrade to v6.1.9 prior to upgrading to v6.2.1. You must also upgrade your BootROM to
BootROM v7.2 to run ExtremeWare v6.1.9 or above. Be sure to perform the BootROM upgrade before
upgrading to ExtremeWare v6.1.9.
Simply TFTP download v6.1.9 to the primary or secondary image space, make sure you are configured
to use that image space, and reboot the switch. Once running on v6.1.9, TFTP download v6.2.1 to the
primary or secondary image space, make sure you are configured to use that image space, and reboot
the switch. We recommend downloading into an image space that is not currently in use. In this way,
the currently used image is preserved should you need to go back. For example, if the primary image
space is used currently, upgrade to v6.1.9 using the commands:
download image <ipaddress> <v6.1.9_filename> secondary
use image secondary
reboot
For detailed instructions on upgrading the BootROM and software images, see the following sections,
“Upgrading the BootROM” and “Upgrading ExtremeWare.”
Note: You must upgrade to BootROM v7.2 to run ExtremeWare v6.1.9 or above. Also note that
you must downgrade to BootROM v6.5 to run ExtremeWare 6.1.8 and below. See below for
instructions on bootROM upgrades.
Upgrading the BootROM
This release is supplied with a new BootROM image for the Summit and BlackDiamond switches. The
new BootROM release is critical to the upgrade aspects of ExtremeWare v6.1.9 and v6.2.1 and is not
backward compatible with ExtremeWare v6.1.8 or previous ExtremeWare v6.1 releases. Be sure to
perform the BootROM upgrade before upgrading to ExtremeWare v6.1.9 using the command:
download bootrom [ <host_name> | <ip_addr> ] <ngboot.bin_name>
Note that BootROM 7.2 is not backward compatible with versions of ExtremeWare prior to 6.1.9. To
downgrade to an earlier version of ExtremeWare, be sure to perform a BootROM downgrade before
downgrading the EW software. To downgrade BootROM, use the following command:
download bootrom [ <host_name> | <ip_addr> ] <ngboot.bin_name>
Once the BootROM downgrade is complete, you can reboot the system with the previously loaded EW
version.
