Configuring a Management IP Interface

Use the following command to specify the links to be used in the stacking trunk:
CN4093(config)# boot stack higig­trunk <list of port names or aliases>
Note: Ports configured as Server ports for use with VMready cannot be designated
as stacking links.
CN4093(config)# reload
To create the recommended topology, attach the two designated stacking links in a
bidirectional ring. As shown in Figure
starting with the Master switch. To complete the ring, connect the last Member
switch back to the Master.

bidirectional
Note: The stacking feature is designed such that the stacking links in a ring
topology do not result in broadcast loops. The stacking ring is thus valid (no
stacking links are blocked), even when Spanning Tree protocol is enabled.
Once the stack trunks are connected, the switches will perform low‐level stacking
configuration.
Note: Although stack link failover/failback is accomplished on a sub-second basis,
to maintain the best stacking operation and avoid traffic disruption, it is
recommended not to disrupt stack links after the stack is formed.
Each switch in a stack can be configured with the external management IP interface
(127). The switch's MAC address must be associated with the management IP
interface. This interface can be used for connecting to and managing the switch
externally. Follow the steps below:
CN4093(config)# interface ip 127
CN4093(config­ip­if)# mac <switch MAC address> ip address <IPv4 address> <subnet
mask> enable
CN4093(config­ip­if)# exit
CN4093(config)# ip gateway 3 mac <switch MAC address> address <gateway IPv4
address> enable
