Identifying Physical Units And Ports In A Stack - Dell PowerConnect M8024-k User Manual

Stacking PowerConnect 10G Switches: M8024-k, 8024, 8024F
Notice there is only one member line in the configuration. If there were three members in the stack
then there would be three member lines in the configuration, such as
stack
member 1 1
member 2 1
member 3 1
Note: A single "stack member" configuration is always present on stack-capable switches even if they
are not part of an actual stack. The single switch is considered a "stack of one".

Identifying Physical Units and Ports in a Stack

The Dell PowerConnect 8024/8024F, and M8024-k hardware did not originally include the stacking
feature that was introduced in firmware 4.2 and therefore do not have all of the hardware features
commonly found on stacking devices such as dedicated stacking ports, locate LEDs, or LCDs displaying
stack unit numbers. Alternative methods to obtain this information are described below.
The M8024-k modular blade switch does have a blue LED illuminating on all stack Masters. Standby and
Member units in the stack do not illuminate this light.
Once stacked, using logging commands is an easy way to find a Unit number, identify order of the
stacked units, and (if using M8024-k) identify the chassis a member unit is in. From the Telnet or Serial
port CLI, perform the following.
console(config)#logging on
From the stack, create a link-up or link-down on any port for two to three seconds by either plugging in
or unplugging a cable, then reversing the action.
command in enable mode.
console#show logging
<189> MAY 21 09:32:49 198.18.101.45 Link Up:Index:301 Unit: 3 Tag: 0/20
If the log file is large, look at or near the end (bottom) to find the most recent entries. The log will
identify both the Unit (i.e. 3) and Port (i.e. 0/20) that was used in the link operation, and show which
physical Unit corresponds with each logical Unit number. Continue this process to identify all logical
Unit numbers in the stack and locate all physical Units in their corresponding chassis. If the show
logging command is full, it can be saved off to another location then cleared for easier reading. Also if
the log is not needed, it can be cleared as well prior to creating the link events.
To now identify which unit is the stack Master and which ones are members, type the following
command.
console#show switch
! PCM8024-k
! PCM8024-k
! PCM8024-k
Check the log on the stack using the following
