Management Access on Stacks
You can access the stack via the console port or VTY line.
• Console access — You may access the stack through the console port of the master unit (stack manager) only. Similar to a
standby RPM, the console port of the standby unit does not provide management capability; only a limited number of commands
are available. Member units provide a limited set of commands.
• Remote access — You may access the master unit and standby unit in a stack through the dedicated management Ethernet
interfaces with SNMP, SSH, or via Telnet.

You can connect two units with two or more stacking cables in case of a stacking port or cable failure. Removal of only one of the
cables does not trigger a reset.
Stacking Installation Tasks
The following are the stacking installation tasks.
• Create a Stack
• Add Units to an Existing Stack
• Split a Stack

Stacking is enabled on the device using the front end ports.
Stack Group/Port Numbers
By default, each unit in Standalone mode is numbered stack-unit 0.
A maximum of eight 10G stack links or two 40G stack links can be made between two units in a stack. The front end ports are
divided into 16 stack groups, each with 40G of bandwidth. Stack groups 0 through 11 correspond to 10G stack groups with four ports
each. Stack groups 12 to 15 are one 40G port each.
