Several questions about the Fabric module of N7K:

When migrating from 1.Fabric 1 to Fabric 2, you must or a later release in Cisco NX-OS 6.0x

2.N7009 does not support Fabric 1

The online migration of 3.Fabric 1 to Fabric 2 must be completed within 12 hours, otherwise there will be a system message, the original text is as follows: When upgrading fabric modules, you must replace all of the Series 1 fabric modules in the switch with Series 2 fabric modules within 12 hours or you will see a syslog message that reminds you to complete the upgrade.

When 4.Fabric 1 migrates offline to Fabric 2 and starts the switch when the two modules coexist, Cisco officials give two diametrically opposed statements, as follows:

You can replace a Series 1 fabric module with a Series 2 module in the Cisco Nexus 7010 and 7018 switches during operations, but while there is a mix of fabric module types, all of the fabric modules perform as Series 1 fabric modules. If you power up a switch with two types of fabric modules installed, only the Series 1 fabric modules will power up. To utilize the Series 2 fabric module capabilities, all of the installed fabric modules must be Series 2 fabric modules.

If you power up a switch that has both types of fabric modules installed, only the Series 2 modules power up. If you need the Series 1 modules to power up, you must first power off all of the Series 2 modules before the Series 1 modules can power up.

With regard to the relationship between the Fabric O module and Fabric, it is mentioned in the training that 5 Fabric 2 modules are needed if you use the F2 Imax O module. Here are some points to be explained:

1. If you use a single F2 Fabric O module, you can configure only 2 IAMP 2 fabric to achieve the redundancy of 1x1, without considering the wire speed, because data transmission between different ports of the same F2 module does not need to go through the fabric.

two。 Based on the above point, the relationship between the Fabric O module and the IWeiO module does not mean that it is impossible to use the IWeiO module or the IWeiO module without Fabric, but how much bandwidth is required for data transmission between different Imax O modules.

3. M1 Gigabit I / O module because the bandwidth of the connection backplane is 40Gbps, two-way 80Gbps, so there must be a Fabric 1 module working properly, otherwise it will not work.
