Logging into a Stack

You can log into any node in a stack, but you can control more stack features when you log into the master. The following guidelines describe the options available to you when you log into different nodes:

On master nodes, all features supported by the switch license operate correctly.
On backup nodes, most show commands show correct data for the active stack. For example, show vlan {virtual-router vr-name} shows all configured VLANs.
On all non-master nodes, most of the configuration commands are rejected. However, the failsafe account, enable license, and stacking configuration commands work on any node.
On standby nodes, most show commands do not show correct data for the current stack operation. However, the show switch {detail}, show licenses, and all show stacking commands show correct data.
If a node is connected to the stack and stacking is not enabled, you can still configure stacking features on that node.

The login security that is configured on the master node applies when logging into any node in the active topology. This includes any active node that is present in a slot. A node that is disabled for stacking is its own master, and uses its own security configuration.

You can log in to a SummitStack node using the following methods:

Console connection to any node
Management connection to the master
Management connection to a standby node
Telnet session over the stack from any active node to any other node in the same active topology
