NETGEAR 8800 User Manual
Before configuring any virtual router parameters for VRRP, you must first create the VRRP
instance on the switch. If you define VRRP parameters before creating the VRRP, you may
see an error similar to the following:
Error: VRRP VR for vlan vrrp1, vrid 1 does not exist.
Please create the VRRP VR before assigning parameters.
Configuration failed on backup MSM, command execution aborted!
If this happens,:
• Create a VRRP instance using the create vrrp vlan vrid command.
• Configure the VRRP instance’s parameters.
Using the Rescue Software Image
WARNING!
The rescue image completely re-initializes the system. All data
residing on the switch is cleared, including configuration files,
policy files, and other system-related files. Use this feature only
with the guidance of NETGEAR Technical Support.
The rescue software image recovers a switch that does not boot up by initializing the internal
compact flash and installing the XCM8800 software on both primary and secondary images
of the compact flash.
NETGEAR 8800 series switches support loading the rescue image to the external compact
flash memory card installed in the MSM. For more information see
Obtaining the Rescue
Image from an External Compact Flash Memory Card on page 843.
Before you begin the recovery process, collect the following information:
• IP address, netmask, and gateway for the switch
• IP address of the Trivial File Transfer Protocol (TFTP) server that contains the XCM8800
image
• XCM8800 image filename (the image has a .xos filename extension)
Note: The rescue process initializes the primary and secondary images
with the XCM8800 software image. No additional software packages
or configuration files are preserved or installed. This process takes a
minimum of 7 minutes to complete. To install additional modular
software packages and configuration files, see
Software Upgrade
and Boot Options on page 801 for more information.
