Netgear XCM8806 - 8800 SERIES 6-SLOT CHASSIS SWITCH ユーザーズマニュアル

If you install the image at a later time, use the following command to install the 

software:

install image <fname> {<partition>} {msm <slotid>} {reboot}

 

Verify that the new backup MSM comes up correctly and that the MSMs are synchronized 
using the following command:

show switch

 

The current state indicates which MSM is the primary (displayed as MASTER), which 
MSM is the backup (displayed as BACKUP), and if the backup MSM is synchronized with 
the primary MSM (displayed as In Sync).

Optionally, initiate failover from the new primary MSM to the new backup MSM using the 
following command:

run msm-failover

When you failover from the new primary MSM to the new backup MSM, this optional step 
restores the switch to the original primary and backup MSM. 

Optionally, confirm that the failover is successful by checking the current state of the MSMs 
using the following command:

show switch

You can also perform a hitless upgrade on XCM8800 modular software packages (.xmod 
files). To perform a hitless upgrade of a software package, you must install the core software 
image first, and the version number of the modular software package must match the version 
number of the core image that it will be running with. 

For more detailed information about modular software packages, see 

on page 806. To perform a hitless upgrade, follow the steps described in 

the previous section, 

on page 812.

Hitless Upgrade Examples

This section provides examples for performing a hitless upgrade on the NETGEAR 8800 
series switches.

Before you begin, make sure you are running a version of XCM8800 

that supports hitless upgrade. For more information, see the list in 
the section 

on page 812. 

Using the assumptions described below, the following examples perform a hitless upgrade 
for a core software image on NETGEAR 8800 series switches:
