Switch Meshing 
Configuring Switch Meshing 
CLI: Configuring Switch Meshing 
Syntax:  [no] mesh [e] < port-list > 
Enables or disables meshing operation on the specified ports. 
[no] mesh backward-compat 
Enables or disables the switch for backward compatible  
mode. This allows the 3400cl, 6400cl, and 5300xl switches  
to interoperate with the 8000M/4000M/2424M/2400M/1600M 
switches in the same switch mesh. 
Note: Enabling this mode turns off some configuration  
checking done in a mesh with only 3400cl, 6400cl, or 5300xl 
switches. This command does not require a reboot to take  
effect. 
All meshed ports on a switch belong to the same mesh domain. Thus, to 
configure multiple meshed ports on a switch, you need to: 
1.  Specify the ports you want to operate in the mesh domain. 
2.  Use write memory to save the configuration to the startup-config file. 
3.  Reboot the switch 
For example, to configure meshing on ports A1-A4, B3, C1, and D1-D3: 
Figure 7-14.  Example of How To Configure Ports for Meshing 
To remove a port from meshing, use the "no" version of mesh, followed by write 
memory and rebooting the switch. For example, to remove port C1 from the 
mesh:
