Understanding Tokens; Checking Tokens Currently Used In A Stack - Alcatel OmniSwitch 6800 Series Hardware User's Manual

Understanding Tokens

Understanding Tokens
OmniSwitch 6800 and OmniSwitch 6800L switches use global module identifiers—referred to as tokens—
for budgeting stack ASIC resources. Each stack offers 32 tokens, with each module added to the stack
using a specific number of these tokens. For a list showing the number of tokens used by each module
type, refer to the table below.
Module Type
OS6800-24
OS6800-24L
OS6800-48
OS6800-48L
OS6800-48 with 10 Gigabit uplink
OS6800-48L with 10 Gigabit uplink
OS6800-U24
OS6800-U24 with 10 Gigabit uplink
Reminder. OS6800-U24 switches do not support stacking.
The maximum allowance of eight modules per stack takes precedence over the number of tokens used. In
other words, although it takes 16 OS6800-24 switches to use up all 32 allotted tokens, no more than eight
switches can be stacked together at any time.
If a switch attempts to join a stack and there are not adequate tokens available, the incoming switch is
automatically placed in pass-through mode. For more information, refer to
page 3-11.

Checking Tokens Currently Used In a Stack

To check the number of tokens currently used in a stacked configuration, use the
command. For example:
-> show stack status
Redundant cable status
Tokens used
Tokens available
In this example, the current stacked configuration is using 12 of the 32 available tokens; this leaves
20 tokens available for any modules brought into the stack.
Note. To view the types of modules (e.g., OS6800-24, OS6800-48, etc.) used in the current stacked
configuration, use the
