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.
S-Series Stacking Installation Tasks
The following are the S-Series stacking installation tasks.
• Create an S-Series Stack
• Add Units to an Existing S-Series Stack
• Split an S-Series Stack
Create an S-Series Stack
Stacking is enabled on the using the front end ports.
No configuration is allowed on front end ports used for stacking. Stacking can be made between 10G
ports of two units or 40G ports of two units. The stack links between the two units are grouped into a
single LAG.
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.
The front end ports accommodate SFP, SFP+ and QSFP+.
• Ports are divided into 16 stack-groups (0 to 15) as shown in the following example. The stack groups
must be of a single speed - either all 10G or all 40G.
